The Royal Thai Embassy in London will only legalise a UK document that already carries the FCDO apostille. Where the document is a copy, a translation or a document you have signed yourself — a power of attorney, affidavit or consent letter — the embassy cannot verify your signature, so it must first be certified by a UK solicitor or notary, then apostilled. We check every document against the embassy’s current requirements before it is submitted.
UK documents are routinely required by Thai authorities for:
Marriage to a Thai national — a UK birth certificate, decree absolute or previous spouse’s death certificate, and often an affidavit of freedom to marry, all legalised for the Thai district office (amphur) that registers the marriage.
Teaching and work permits — degree certificates, transcripts and TEFL certificates for the Thai Teachers’ Council and Ministry of Labour, plus an ACRO police certificate for the work permit and Non-Immigrant B visa.
Retirement and family visas — marriage certificates, birth certificates and police certificates for Non-Immigrant O and O-A applications.
Business and property — certificates of incorporation, good standing, board resolutions and powers of attorney for setting up a Thai company, opening a bank account or buying a condominium. Foreigners’ signatures on real-estate documents must be certified by a UK solicitor or notary and apostilled before the embassy will legalise them.
Family matters — consent letters for a child’s Thai passport, adoption papers, custody orders, and surname changes on Thai ID and house registration following marriage or divorce.

The Royal Thai Embassy can certify translations between English and Thai. For an English-to-Thai translation, the original document must first be apostilled and legalised by the embassy; the translation is then signed by the translator with the statement “Certified Correct Translation” and submitted to the embassy for certification. We arrange the translation and the certification together with the legalisation, so the documents arrive in Thailand ready for the Ministry of Foreign Affairs. Send us a scan of the document and we’ll advise the cost and the next step.

Legalisation of documents for Thailand is mandatory if you’re planning to work, study, or do business in the country. The process can feel overwhelming because it involves multiple departments and the Thai Embassy. That’s where we step in.
At Apostille and Certification Services Ltd, we provide professional Thailand embassy legalization services in UK, ensuring your documents move smoothly through required authorities.
While we don’t legalise the documents ourselves, we manage every step on your behalf efficiently.
Royal Thai Embassy, Consular Section · 29–30 Queen’s Gate, London SW7 5JB · Legalisation hours Monday–Friday 09:00–12:00
Our full service takes 5 to 6 working days from the day we receive your documents: solicitor certification where needed, the FCDO apostille and the embassy stamp. The embassy’s own processing time is 3 working days, excluding delivery.
£185 per document, personal or commercial. That includes solicitor certification where needed, the FCDO fee, the embassy fee and our handling. If your document already has an apostille, the embassy stage alone is £70 per document.
For most uses in Thailand — marriage registration, work permits, company registration, property — yes. The Thai authority will want a Thai translation, legalised by the Ministry of Foreign Affairs in Bangkok. The embassy in London can certify the translation once the original has been legalised. Send us a scan of the document and we’ll advise the cost and the next step.
Yes. A TEFL, TESOL or CELTA certificate is treated like any other educational document: certified by a solicitor, apostilled, then legalised by the embassy. Thai schools usually ask for the degree certificate and an ACRO police certificate as well.
The embassy has no time limit, but Thai immigration and the Ministry of Labour generally want a police certificate issued within the last 3 to 6 months. Order the certificate first, then the legalisation, so it’s as fresh as possible when you apply.
The embassy cannot verify a foreigner’s signature, so the document must be signed in front of a UK solicitor or notary, apostilled, and then legalised by the embassy. Many Thai land offices require a notary rather than a solicitor — tell us the purpose and we’ll advise. Notary fees are separate; contact us before paying.
Not for legalising a document that already carries an apostille — we submit and collect on your behalf. Some services do require the person to attend the embassy in person, for example a Thai national signing a power of attorney or a parent signing a consent letter for a child’s passport; the embassy will not accept those by post or through an agent.
For birth, marriage, death and divorce certificates and ACRO or DBS certificates, yes — the FCDO apostilles the original. Degree certificates and most other documents can be done from a solicitor-certified copy, so you keep your original. The order form tells you which applies to each document.
No. Thailand is not a member of the Hague Apostille Convention, so the apostille alone isn’t enough — the Royal Thai Embassy must also legalise the document. Our service covers both.
Yes. Choose DHL International on the order form and we’ll courier the legalised documents to an address in Thailand.
Our specialists manage every step of the legalisation process, delivering internationally recognised certification quickly and efficiently.
We have a strict non-disclosure and privacy policy which ensures that none of your personal data ever gets out because it is handled with care.
Plus we also wholly comply with the Data Protection Act of the UK.
