What a Letter of Invitation Actually Is
A letter of invitation is a letter one person or one organisation writes to say: I know this person, I am asking them to come, and here is what I am putting behind that request. It has no fixed legal form in England and Wales — no statute defines it, no register records it, no official issues it. You write it and you sign it.
That is the single fact everything else here follows from. A letter of invitation is a private document. It sits with personal references and company letters on headed paper — documents that carry real weight with the people who read them, and no formal status at all with the office that issues apostilles.
📝 The same document under a dozen different names
Half the confusion here is vocabulary. A letter of invitation, an invitation letter on company letterhead, a sponsorship letter, a letter of support, a letter of guarantee, an affidavit of support and a statutory declaration of support are, for legalisation purposes, one thing: a document signed by a private person or a company. All of them need certification before an apostille can attach, and none of them is treated differently from the others by the FCDO. The only distinction that matters is that an affidavit or a statutory declaration already contains the certification step by definition, because you swear or declare it in front of the professional.
One group of documents that shares the name is genuinely different. An attestation d'accueil (France), a Verpflichtungserklärung (Germany), a carta de invitación (Spain) or a Dutch proof of sponsorship and/or private accommodation form is not a letter you write — it is issued by an authority in the destination country. None of them can be produced or apostilled in the UK, and section three explains why that saves people the most money of anything on this page.
👤 The two people in every invitation letter
Every invitation letter has a writer and a reader, and the legalisation question turns entirely on the reader. People instinctively focus on the writer — making the letter look formal, adding stamps — when the only question that matters is: which authority, in which country, is going to open this envelope?
🌐 Which direction is your letter travelling?
We ask every caller this before quoting, because it settles the answer faster than anything else. An invitation letter can travel in only three directions, and only one of them ever needs our service.
UK host → UK authority (a visit to Britain)
You live in the UK, you are inviting someone to visit or join you here, and the letter goes into a UK visa application read by UK Visas and Immigration. No apostille — genuinely none. The Convention does not apply to a document produced in the same state it was made in, and the Home Office's own guidance puts notarial certificates among the documents that carry little weight. This is the largest single group of people who find this page, and the group we turn away.
UK host → foreign authority (the letter leaves the country)
You write the letter in the UK and it is submitted to a ministry, consulate, court, university, employer or migration office abroad. This is the only direction in which legalisation is ever in play, and even here only if that foreign body has actually asked for it. Section four is about how to tell.
Foreign host → anyone (the letter was written abroad)
Someone abroad has written you an invitation and you want it apostilled in London. Nobody in the UK can. GOV.UK is explicit that you cannot get documents issued outside the UK legalised using the FCDO service — a document is apostilled in the country where it was made, by that country's own competent authority.
Direction B is where the rest of this guide lives. In direction A or C you can stop reading now, with our blessing, and keep your £120 — though section three is worth two minutes if you need the reasoning in writing for a relative who insists otherwise.
Why It Cannot Be Apostilled on Its Own
This is the mechanical heart of the subject, and worth understanding rather than just accepting: once you see how the FCDO Legalisation Office works, every other rule on this page becomes obvious instead of arbitrary.
🏛️ What the FCDO is actually checking
The Legalisation Office does not read your document, and has no view on whether its contents are true. It does exactly one thing, and GOV.UK describes it in a single sentence: the office will “check the document and see if any signatures, stamps or seals match their own records”.
Those records are the point. The FCDO maintains specimen signatures and seal impressions for the officials and professionals whose documents it authenticates — registrars, court officers, government departments, registered doctors, and the solicitors and notaries who are on its list. When a document arrives, the office compares what is on the paper with what is in the file. Match found, apostille issued. No match, document returned.
❌ Why your own signature fails this test
The FCDO does not hold a specimen of your signature. It has no way of knowing that the person who signed “A. Kowalski” at the bottom of a letter is the A. Kowalski who lives at that address, or that any such person exists. There is nothing to compare against, so there is nothing to authenticate. This is not the FCDO being obstructive — it is the only honest position an authentication office can take about a private signature it has never seen before.
📜 What GOV.UK says you can do about it
The same guidance that lists what the office can legalise — court documents with a wet ink seal, public registry certificates, government department letters signed by an official, medical certificates signed by a registered doctor — then adds the sentence that this entire article exists to explain:
“You can also get other documents legalised, as long as they have been certified by a UK ‘public official’, such as a UK notary or solicitor.” — GOV.UK, Get your document legalised
The same page names the kinds of document this route is for: “documents such as a power of attorney, a contract or a qualification certificate”, and “copies of documents such as a passport or a driving licence”. A letter of invitation is not named — no list of examples covers everything — but it sits squarely in that family: a private document that becomes legalisable the moment a certified professional puts their own signature and seal on it.
⚖️ The Convention wrote this rule sixty years ago
The mechanism is not a British invention or an FCDO policy choice. It is written into Article 1 of the 1961 Convention itself, which defines the public documents the treaty covers. Alongside court documents, administrative documents and notarial acts, sub-paragraph (d) covers:
“official certificates which are placed on documents signed by persons in their private capacity, such as official certificates recording the registration of a document or the fact that it was in existence on a certain date and official and notarial authentications of signatures.” — Article 1, Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents
Read that clause slowly, because it contains the whole answer. The Convention does not make a privately signed letter into a public document. What it does is recognise the official certificate placed on that letter as a public document in its own right. The letter stays private forever. The certificate is public. The apostille attaches to the certificate.
🔗 The chain, drawn out
1. Your letter, your signature
A private document. Invisible to the FCDO. No status under the Convention.
2. Solicitor or notary certificate
A UK public official witnesses your signature and attaches their own certificate, signature and seal. This is the public document the Convention recognises.
3. FCDO apostille
The Legalisation Office matches the professional's signature and seal against its records and attaches the apostille.
4. Embassy legalisation — non-Convention destinations only
The destination's embassy or consulate in London stamps the apostilled bundle. Section five explains who needs this.
Notice what the apostille is not attached to. It is not attached to your promise. It is attached to a professional's confirmation that a person holding certain identity documents signed a page in front of them.
🔍 What the apostille certifies — and what it does not
Article 5 of the Convention states the effect of the certificate, and it is narrower than almost everyone assumes. The apostille “will certify the authenticity of the signature, the capacity in which the person signing the document has acted and, where appropriate, the identity of the seal or stamp”.
Three things. A signature is genuine. The signer held the office they claimed. The seal is the right seal. That is the complete list. There is no fourth limb covering the truth of the contents, and no reading of the Article that would let one in.
❌ What the apostille does not certify
- Not that the British government approves the invitation — the FCDO never read it.
- Not that you own the property. That is proved by a Land Registry title register.
- Not that you can afford the visit. That is proved by bank statements showing where the money came from.
- Not that the relationship is genuine. That is proved by birth and marriage certificates.
- Yes: that a real UK solicitor or notary signed the certificate. That is the entire content of an apostille.
This changes what you should spend money on. If a foreign officer doubts you can support a visitor, an apostille answers a question nobody asked; evidence answers the doubt. An apostille is worth buying only when the receiving authority has made authenticity itself a formal requirement.
Think of it as a stamp on the envelope, not an endorsement of the letter inside. The same logic runs through every private document we handle — a power of attorney takes exactly the same route, and our FCDO apostille process guide spends most of its length on the certification step rather than the apostille.
When You Do Not Need an Apostille At All
Most of the people who arrive on this page do not need what we sell, and we would rather say so in the third section than take an order that was never necessary. Here are the situations in which the correct spend on legalising your invitation letter is £0.
🇬🇧 The UK visitor visa: the biggest single misunderstanding
A large share of the searches that lead here come from UK residents inviting a parent, sibling or friend, who have been told — usually by a well-meaning relative, sometimes by a visa agent abroad who charges for the extra step — that the invitation letter must be notarised and apostilled.
It must not. The Home Office publishes a Guide to supporting documents: visiting the UK, and it goes out of its way to list the documents that carry little weight in a visit application. On that list, alongside old bank statements, credit card statements, driving licences, photographs, business cards, hotel and flight bookings and travel insurance, sits the phrase “notarial certificates”.
⚠️ Read that again
The department that decides your visitor's application has published a document telling you that notarial certificates are among the least useful things you can send. Paying a solicitor and then the FCDO to attach one is not neutral — it spends money and days on an item the caseworker has been guided to discount, and it can suggest a file assembled by someone who does not know what the decision actually turns on.
What the same guidance does ask for, where a sponsor is supporting the visit, is evidence: what support is being provided and whether it extends to dependants; how the support is being provided; that the sponsor has enough funds to support themselves and their dependants as well; the relationship between the applicant and the sponsor; and that the sponsor is legally in the UK — a British passport or a residence document. Financial evidence must clearly show access to the funds, with bank statements that detail their origin, and anything issued more than a year before the application date is treated as stale.
💵 Where the £120 is better spent on a UK visit application
- ✓ Six months of bank statements that show where the money came from, not just that it is there
- ✓ Proof of the host's immigration status — passport bio page, BRP, eVisa share code or residence document
- ✓ Proof of the accommodation offered — tenancy agreement, mortgage statement or title register
- ✓ Evidence of the relationship — birth or marriage certificates, years of photographs, call logs
- ✓ Evidence the visitor will return home — employment, property, dependants, studies
- ❌ Not: a notarised, apostilled invitation letter
If your visa agent insists otherwise, ask them to point to the line in the published guidance that requires it. In fifteen years we have never been shown one.
🇪🇺 Schengen: the hosting document is issued abroad, not here
The second big category is people inviting someone to a Schengen country, or people told to get a “legalised invitation” from a European host. In several of the largest Schengen states the document that matters is not a letter at all but an official form issued by an authority in the destination country, and no UK apostille substitutes for it.
| Destination | The document that actually counts | Who issues it, and where |
|---|---|---|
| DE Germany | Verpflichtungserklärung (formal obligation) | The German Federal Foreign Office states the sponsor “must apply for this standardized formal obligation… at the competent immigration office” — the Ausländerbehörde, usually at their local city administration in Germany. Only the original is accepted. |
| FR France | Attestation d'accueil | Requested by the host at the mairie of the planned accommodation, for a tourist stay of under three months, at €30 in tax stamps. |
| NL Netherlands | Proof of sponsorship and/or private accommodation | The Dutch government's Schengen checklist says the form must be signed by the person who issued the invitation and “must be legalised by the Dutch municipality where that person is registered” — the gemeente. |
| ES Spain | Carta de invitación | Applied for by the host at a Spanish National Police station on appointment, with fees payable at the appointment and on collection. Confirm current practice with the Policía Nacional. |
In every one of those four cases the document is issued abroad, by a foreign authority, to a resident of that country. Nothing written in the UK substitutes for it, and no apostille makes it one.
There is a real trap here. Because all four countries are parties to the Apostille Convention, people reason: Hague country, therefore apostille. That is backwards. Membership tells you which route applies if authentication is required at all; it never tells you that it is required. Most documents crossing most borders need no apostille, because nobody asked for one.
🇨🇳 Consulates that ask for an invitation and nothing more
Plenty of visa systems require an invitation letter and are entirely silent about notarisation. The Chinese consular notice on visa application requirements, for example, asks for “an invitation letter issued by a Chinese citizen or a foreign citizen with a Chinese permanent residence permit who lives in China” for family visit categories, and says nothing about notarisation or legalisation. Where a checklist is silent, silence means not required — not required but unstated. Notice too which way that invitation travels: written in China, for China's own visa system. It is a direction C letter and no British office can touch it.
💭 The three-question test
If you want to settle this in under a minute, answer these three questions in order. The first “no” ends the process.
1. Will the letter be read by an official body outside the UK?
If it is going to UK Visas and Immigration, a British university, a British bank or a British employer, stop. The Convention is about documents crossing borders. No → no apostille.
2. Has that body asked, in writing, for the letter to be notarised, legalised, apostilled or attested?
Not “the agent said”, not “my cousin's file needed it”, not “a forum said”. A published checklist, an official email, a printed requirement list. No → no apostille. Ask them before you spend anything.
3. Is the invitation letter itself on the list, rather than the other documents in the file?
This one catches people constantly. Many requirement lists say “all documents must be legalised” and then, in the body of the list, name birth certificates, marriage certificates and qualifications — with the invitation sitting under a separate heading as a plain supporting item. Read the list twice. No → no apostille.
Three yeses and you are in the minority who genuinely need the service. Call us and we will do it properly and quickly. Anything less than three and we will tell you to keep your money — which, given that we are the ones being paid, is a position you can probably trust.
When a Legalised Invitation Letter Genuinely Is Required
Having spent a section telling people not to buy, here is the other half of the honest answer. There is a real, recurring set of situations in which an invitation or sponsorship letter written in the UK has to be certified and apostilled.
We describe these by who is reading the letter rather than by country, deliberately. Consular requirements change without announcement, differ between two consulates of the same country, and sometimes differ between two applicants at the same counter on the same day. Any guide publishing a fixed list of “countries that require an apostilled invitation” is publishing something that will be wrong somewhere within a month. What does not change is the pattern of reader.
🏢 Reader 1: a foreign ministry, migration office or consulate
The classic case. A family member or business contact abroad is applying for something — a long-stay visa, a residence permit, an exit clearance, a family reunification file — and the receiving office wants proof that the UK-side undertaking is real. It cannot verify a British signature, so it asks for the chain it does understand: a certified signature carrying an apostille.
You will usually recognise this by the vocabulary. Civil-law requirement lists use words like legalizado, légalisé, beglaubigt, notarially certified, attested or apostilled next to a named document. Where those words appear against the invitation itself, take it at face value and do the full chain.
🎓 Reader 2: a university, ministry of education or scholarship body
Invitation and sponsorship letters travel a great deal in academic settings: a UK institution or a UK-based relative undertaking to host and fund a visiting researcher, a postgraduate student or a school-age child. Education ministries administering state scholarships are, in our experience, among the most likely bodies to insist on formal authentication, because they are releasing public money against the undertaking. If the letter is going into a file that releases funding, expect authentication to be asked for.
💼 Reader 3: a foreign employer, ministry of labour or immigration sponsor
A UK company inviting an overseas colleague, contractor or supplier sometimes finds the invitation has to be authenticated — not by the British side, but by the visitor's own authorities, before granting leave, an exit permit or travel approval. Letterhead is worthless as authentication abroad, so the chain begins again with a solicitor or notary. On a corporate letter the certifying professional will usually want proof that the signatory can bind the company: bring the Companies House record or a letter of authority.
⚖️ Reader 4: a foreign court, notary or civil registry
Invitation-style letters appear in family proceedings abroad more often than people expect — an undertaking to host a child during school holidays, a statement of support in a custody or maintenance matter. Courts and civil registries deal in authenticated documents as a matter of routine and a plain letter will not be filed. Where a court is the reader, the certification is very often required to be a notarial act rather than a solicitor's certificate; section six explains the difference.
🏦 Reader 5: a destination outside the Apostille Convention
If the destination is not a Contracting Party the requirement is often broader: those systems tend to legalise everything in the file, because consular legalisation is their normal mechanism for accepting foreign paper. Section five covers this route, including a caution about assuming an embassy will handle a document type that is not on its published list.
🚫 Two things that are not triggers
“It will look more official” — officials who read documents professionally are not impressed by unnecessary stamps, and a fair number read them as a sign that someone is compensating for weak substance. If authentication was not asked for, adding it changes nothing about how the letter is weighed.
“A previous application needed it” — different visa category, different consulate, different year, different rule. The strongest evidence about your case is the checklist you were handed for your case. Everything else is anecdote, including ours.
✉️ The four questions to put to the receiving authority
When you contact the body that will read the letter, ask these four things together. It is one email and it prevents the two most expensive mistakes in this field — buying a certification nobody wanted, and buying the wrong one.
- Does the invitation letter itself need to be authenticated, or only the supporting civil documents?
- If yes: solicitor certification or a notarial act? Some readers accept either; many civil-law bodies want a notary specifically.
- Apostille only, or apostille plus consular legalisation? This depends on the destination, not on the document.
- What language, and who must translate? Some authorities require a translation produced in their own country by a sworn translator; that decides the order of operations for you.
Get the answers in an email you can keep. If the answer contradicts something on this page, the answer wins — and we would genuinely like to see it, because it helps us keep this guide accurate.
Apostille or Embassy? What the Destination Decides
Once the letter does need authenticating, one thing decides how long the chain is: whether the destination is a Contracting Party to the 1961 Apostille Convention. Nothing about the letter itself affects this. The same certified invitation goes two stops if the destination is in the Convention and three if it is not.

📜 Why the embassy stage exists at all
A country outside the Convention has not agreed to accept a foreign certificate as sufficient, so it verifies foreign documents through its own diplomatic mission — and only once the sending state has authenticated them first. The UAE Embassy in London states the sequence in its own guidance: documents issued in the UK must be attested by the Foreign, Commonwealth & Development Office, and other documents need prior authentication by a solicitor or notarisation by a notary public in the UK before that stage.
The Qatar Embassy in London sets out the same shape of process for its legalisation service — certification by an accredited solicitor, then an individual apostille from the Foreign Office, then submission to the embassy's legalisation department — and adds a practical warning worth repeating: documents certified or apostilled in a bundle will not be accepted; each document must be certified and apostilled individually. Its published personal-document fee is £24 per document, its commercial fee £36, and it states the service takes a minimum of four to five working days with no express option.
⚠️ A caution we would rather give you now than after you have paid
Embassies legalise the document types on their published lists. Qatar's personal-documents list, for instance, names police clearances, fingerprints, passport copies, driving licences, medical reports, birth, marriage and divorce certificates, court orders, wills, change-of-name notifications and personal powers of attorney. A letter of invitation is not on it. That does not automatically mean the letter would be refused — missions handle documents outside their headline lists all the time, and a notarial act on a letter is a recognisable instrument — but it does mean you should never assume. Before we quote for an embassy route on a letter, we check with the mission that they will take that document type. If they will not, we say so and you have lost nothing.
🌐 Which destinations are outside the Convention?
We check this against the HCCH status table on every order rather than from memory, and we would encourage you to do the same — the list has moved considerably in the last four years and most country guides on the web have not kept up. On the date of writing the Convention has 130 Contracting Parties.
🚫 Common destinations that are not Contracting Parties
For all of these a certified invitation letter needs solicitor or notary certification, then the FCDO apostille, then legalisation at the country's embassy or high commission in London — our route from £150 per document.

This is not the complete list of non-Contracting States — it is the set we are asked about most often. Check your own destination before ordering, or use our What Do I Need? tool, which covers 127+ countries.
Moving Destinations that are about to change
Two destinations that many guides still list as embassy-only have acceded to the Convention with a future effective date, and the difference between accession and entry into force is exactly the kind of detail that gets a file rejected.
✅ Destinations people wrongly assume still need an embassy
Every week someone asks us to arrange embassy legalisation for a country that has been in the Convention for years. India has been a Contracting Party since 14 July 2005, Saudi Arabia since 7 December 2022, Pakistan since 9 March 2023, China since 7 November 2023 and Bangladesh since 30 March 2025. Algeria joined the list on 9 July 2026. For all of these, a certified letter needs an apostille and nothing more — £120 rather than from £150, and days rather than weeks. If a guide or an agent tells you otherwise, check the HCCH table before you pay.
Solicitor or Notary Public — Which One You Need
For the FCDO's purposes the two are interchangeable: GOV.UK names “a UK notary or solicitor” in the same breath, and the Legalisation Office will apostille either professional's certificate. For the authority reading your letter at the other end, they are frequently not interchangeable at all. This section is about telling the difference before you pay rather than afterwards.
| Solicitor | Notary public | |
|---|---|---|
| Primary role | Acts for a client, in that client's interest | A public officer whose duty runs to the transaction and the recipient abroad, not only to the client |
| What they produce on a letter | A certificate of witnessing or a certified true copy, signed and stamped | A notarial act — a formal instrument under the notary's own seal, drafted for international use |
| Accepted by the FCDO? | Yes | Yes |
| Accepted abroad? | Usually in common-law jurisdictions; often refused by civil-law bodies | Safer almost everywhere, and the only answer some courts and registries accept |
| Typical cost | Included in our £120 combined service | Charged by the notary, commonly more than a solicitor's fee; quoted on request |
| Register | Solicitors Regulation Authority (England & Wales) and equivalents | The Faculty Office; professional body the Notaries Society |
🎯 How to decide in one question
Ask the receiving authority which they require. If you cannot get an answer, apply this rule of thumb: the more the reader looks like a court, a land registry, a civil registry or a notary's office, the more likely a notarial act is required. Civil-law systems — most of continental Europe, Latin America, much of the Middle East and North Africa — are built around the notary as the person who gives a private document public force; a solicitor's certificate is not a thing those systems have. Where the reader is a consulate processing a visa file, a solicitor's certificate is usually fine. Where it is a ministry releasing money or a court making an order, do not economise.
💰 The most expensive mistake in this whole guide
Buying solicitor certification plus an apostille, sending it abroad, and being told the authority requires a notarial act. You then pay for a notary, pay the FCDO again, and lose the postal time twice — typically two to three weeks and well over £200, on a question that one email would have settled. If you are unsure and the destination is a civil-law jurisdiction, going straight to a notary is usually the cheaper decision even though it is the higher invoice.
📄 Three different things a professional can certify
Clients often ask for “the letter to be notarised” without knowing which of three quite different services they want. The distinction matters because the wrong one is as useless as no certification at all.
Witnessing your signature
You sign in the professional's presence, they verify your identity and certify that they saw you sign. This is what an invitation letter normally needs. The letter must be unsigned when you arrive — a signature applied at the kitchen table cannot be witnessed retrospectively.
Certifying a true copy
The professional compares a copy against an original and certifies it as a true copy. Useful for the passports, residence documents and title deeds you attach — and pointless on the letter itself, because a true copy of an uncertified letter authenticates nothing about the signature.
Administering an oath, affirmation or statutory declaration
You swear or solemnly declare that the contents are true and the professional records it. This converts the letter into an affidavit or statutory declaration — a stronger instrument, and often what a foreign body means by “affidavit of support”. Say so at the outset; it changes the wording.
🔑 What to take to the appointment
💼 Bring all of this — a wasted appointment costs a day
- ✓ The letter, printed, unsigned, on a single-sided print
- ✓ Photographic ID — passport or photocard driving licence, in date
- ✓ Proof of address dated within three months — utility bill, bank statement, council tax bill
- ✓ Evidence of your UK status if the letter asserts it — passport, BRP, eVisa share code or residence document
- ✓ Any document the letter refers to, so it can be described accurately — tenancy agreement, title register, employment contract
- ✓ For a company letter: proof of the signatory's authority and the Companies House record
- ✓ The written requirement from the receiving authority, if you have one — it tells the professional what wording is needed
On our £120 service this is the part we take off your hands: solicitor certification and apostille arranged as one job, completed document returned to you. We still need the same identity evidence, but you are not chasing two appointments and a courier.
What the Letter Should Contain
A certified letter is only as good as the letter underneath the certificate. The professional will witness whatever you put in front of them; they will not improve it. Here is the structure that survives scrutiny, whether or not it ends up carrying an apostille.
[Your full name]
[Your full UK address, including postcode]
[Telephone] · [Email]
[Date]
To: [the authority that will read this — name it]
Re: Invitation to [full name as it appears in the passport], passport no. [number], born [date of birth], national of [country]
1. Who I am. I am [name], born [date], a [British citizen / settled person / holder of leave to remain] resident at the address above since [date]. My occupation is [role] with [employer].
2. My relationship to the invitee. [Exact relationship, how long you have known them, and how the relationship is evidenced — name the certificates you are attaching].
3. What I am inviting them to do. To [visit / stay / attend] for [purpose], arriving on or about [date] and departing on or about [date] — a stay of [number] days.
4. Accommodation. They will stay at the address above, which I [own / rent under a tenancy dated …]. The property has [number] bedrooms and [number] people currently live there.
5. Costs. I will meet [all / the following] costs: [accommodation, subsistence, internal travel, return airfare, medical insurance]. My net monthly income is [amount] and I attach [number] months of bank statements.
6. Undertaking. I undertake that the invitee will comply with the conditions of any visa granted and will leave at the end of the permitted stay. I make this statement knowing it may be relied upon by [the authority].
7. Attachments. [List every enclosure and number it].
Signature to be applied in front of the certifying solicitor or notary — do not sign before the appointment. [Printed name]
If the letter is going to be certified and apostilled, print it single-sided and leave the last page with room at the foot: the professional's certificate and the apostille both need somewhere to attach, and a page crammed to the margin often has to be reprinted at the appointment.
The Process, Step by Step
Assuming you have established the letter genuinely needs authenticating, this is the whole job from a blank page to a document in the hands of a foreign official.
Step 1 — Get the requirement in writing (before anything else)
Confirm with the receiving authority: is the letter itself to be authenticated, solicitor or notary, apostille only or apostille plus consulate, and what language. Everything downstream is decided here, and getting it wrong is the only mistake that costs you the whole fee twice.
Step 2 — Draft the letter, unsigned
Use the structure in section seven. Print single-sided. Do not sign it.
Step 3 — Certification by a solicitor or notary (same day)
You sign in their presence with the identity documents listed in section six, and they attach their certificate, signature and seal. This is the step that turns a private letter into something the Convention recognises.
Step 4 — FCDO apostille (next working day with us)
The Legalisation Office matches the professional's signature and seal against its records and attaches the apostille. The FCDO's standard postal service is usually up to 25 working days plus postage, at £45 per document. We use the registered next-day channel, so a document reaching us in the morning is normally apostilled the following working day.
Step 5 — Embassy legalisation (non-Convention destinations only)
The mission stamps the apostilled document. Timing belongs entirely to the consulate — Qatar's London embassy publishes a minimum of four to five working days with no express service. Each document goes individually, not as a bundle.
Step 6 — Translation, last
Translate the letter, the certificate and the apostille together, once every stamp is physically on the document. A translation produced earlier cannot cover the apostille, and files are routinely returned for exactly that. Some countries insist the translation is produced in-country by a sworn translator. Our apostille and translation guide covers the order of operations country by country.
Step 7 — Send it, and keep a scan of everything
Scan the completed bundle before it leaves your hands, including the apostille number. If the document goes missing in the post, the reference on the apostille is what lets the FCDO confirm it was issued.
⏰ Realistic total timings
Convention destination, our service: two to four working days from receipt, including certification, apostille and return delivery. Non-Convention destination: add the consulate's own processing, which is outside anyone's control and is commonly one to two weeks. Doing it yourself through the FCDO's standard postal route: add up to 25 working days plus postage on the apostille step alone. Plan backwards from the date the letter must be submitted, not the date someone travels.
Paper Apostille or e-Apostille?
The FCDO issues apostilles electronically as well as on paper, and a certified letter of invitation is one of the document types that can, in principle, take the electronic route. Whether it should is a different question.
| e-Apostille | Paper apostille | |
|---|---|---|
| FCDO fee | £35 | £45 plus courier or postage |
| FCDO turnaround | Up to 2 working days | Usually up to 25 working days on the standard service; next working day through us |
| Form | A signed PDF, no post | A physical certificate attached to the document |
| Signature requirement | The document must be electronically signed by a UK notary or solicitor, using an Advanced or Qualified Electronic Signature | Wet ink certificate and seal |
| Non-Convention destination | Useless — embassies stamp paper | The only option where a consular stage follows |
The FCDO's e-Apostille service excludes GRO certificates, ACRO police certificates for England and Wales, DBS certificates, Scottish and Northern Irish disclosure certificates, fingerprint certificates and ACCA membership certificates. A certified invitation letter is not on that exclusion list.
The harder condition is acceptance at the other end. When the service launched the government noted that UK e-Apostilles “have been accepted by authorities in Italy, the Netherlands, Panama and the Philippines”, and that countries signed up to the Convention should equally accept them. Should is doing a lot of work in that sentence. Our position is unglamorous: use an e-Apostille when the receiving authority has told you it accepts one, and paper otherwise. Our e-Apostille versus paper comparison covers the trade-off.
Ten Mistakes That Get Invitation Letters Rejected
Drawn from the files that come back to us, roughly in order of how often we see them.
1. Buying an apostille for a UK visitor visa
Money spent on an item the Home Office guidance lists among the less useful ones. Nothing gained, days lost.
2. Signing the letter before the appointment
A signature cannot be witnessed after the event. The letter is reprinted and re-signed — a wasted day if you posted it.
3. Getting solicitor certification where a notarial act was required
The single most expensive error on this list. One email to the receiving authority prevents it.
4. Translating before the apostille
The translation cannot cover a certificate that did not exist when it was produced. Translate last, and translate the whole bundle.
5. Assuming a Convention country needs an embassy stamp — or that a non-Convention one does not
Both directions happen. Check the HCCH status table, not a country guide of unknown vintage.
6. Sending documents to a consulate in a bundle
Qatar's London embassy states that documents certified or apostilled in a bundle will not be accepted, and others take the same line. Do each document individually.
7. Name mismatches between the letter and the passport
Transliterated names, middle names dropped, married versus maiden names. Copy the passport character for character.
8. Detaching or re-stapling the apostille
Removing the staple to photocopy the document and re-attaching it destroys the physical link. Scan it as it is, or not at all.
9. Trying to apostille a letter written abroad
GOV.UK is explicit that documents issued outside the UK cannot be legalised through the FCDO service. Authentication happens in the country of origin.
10. Planning from the travel date instead of the submission date
The deadline that matters is when the letter must be in the authority's hands. Work backwards from that, plus the consulate's own timetable.
Costs, Timelines & How We Handle It
Plain numbers, and an explanation of why the invitation letter never qualifies for the cheaper price.
| Service | Price | Applies to an invitation letter? |
|---|---|---|
| Apostille, no solicitor required | £90 | No. This price is for documents that go straight to the FCDO — GRO certificates, ACRO certificates, court documents. A private letter never qualifies. |
| Apostille with solicitor certification | £120 | Yes — this is the invitation letter price. Certification and apostille as one job, next working day. |
| Embassy or consular legalisation | From £150 | Only where the destination is outside the Convention. Plus the mission's own fee and its own timetable. |
| Notarial act instead of solicitor certification | Quoted | Where the receiving authority requires a notary. Tell us before you order and we will price it properly. |
For reference, the FCDO's own fees are £45 for a standard paper apostille plus courier or postage and £35 for an e-Apostille. Our prices include the FCDO fee, the certification, the registered next-day submission and return delivery.
