Thailand Embassy Document Legalisation in London, UK

How do I legalise my documents for Thailand?

Legalisation is the process by which a document is authenticated for international use within a foreign country. The Hague Convention of 1961 abolished the requirement of legalisation of public documents to be used for cross-border purposes by the signatory nations of the convention. This abolished the cumbersome chain authentication method, which involved verification by multiple authorities. Over 100 countries are signatories to this agreement.

Thailand is not a signatory member of The Hague Convention of 1961 that abolished the requirements for legalisation of foreign public documents and therefore all the UK-issued documents to be used in Thailand, for various purposes including work and education, need to be legalised by the Embassy of Thailand in London, in addition to having an apostille certification.

The process of legalisation of documents for use in Thailand involves several stages:

  1. All the documents that have originated in the UK and need to be used or presented in Thailand for work and business purposes need to be submitted to the Thailand Embassy in London for legalisation.
  2. Before submitting these documents to the Thailand Embassy for legalisation, one needs to get them apostilled by the Foreign and Commonwealth Office or FCO, the competent authority in the UK for issuing the apostille certificate. The apostille certification is required for international acceptance of documents to be used for work, business, legal issues and even personal matters, such as overseas marriage, registering of birth and foreign property purchases.
  3. The FCO may require certain documents to be notarised, which  means signed and dated by a Notary Public or a UK Solicitor registered with the regulatory body. The Notary Public or Solicitor will check the documents and attach a certified cover sheet, besides stamping them to verify authenticity.

The process of legalisation of your documents by the Thailand Embassy in London can only be completed after your documents are notarised and apostilled by the competent authorities. The documents need to be submitted to the Thailand Consulate in the required format, along with the legalisation form and fees. The Thailand Embassy in London accepts photocopies of the documents, with no restrictions on bundling them. offers a wide range of services associated with the legalisation of UK-issued documents to be used in any other country across the world. Our experienced consultants are well-acquainted with the entire process and have built strong relationships with various government and consulate offices to ensure that the process can be completed in the shortest possible time.

We also offer translation services, where required, through a network of qualified and experienced translators, belonging to the Institute of Translators and Interpreters, as well as the Institute of Linguists.

Important Notes for Thailand Embassy Legalisation

Remember that since Thailand is not a part of The Hague Apostille Convention of 1961, all foreign documents presented in the nation, for the purposes of work, business, education or residence,  need to be legalised, in addition to having an apostille certificate. Legalised documents also help in opening bank accounts in Thailand.

All documents submitted to the Thailand Embassy in London for legalisation need to be apostilled by the UK FCO, and in some cases, notarised as well. The Consulate of Thailand accepts photocopies of documents, along with a fully filled legalisation form. There is no restriction regarding the bundling of documents. The consular fee of £10 per document to be legalised, payable in cash only.

The team at is well-versed with the rules and requirements for the legalisation of UK-issued documents for use in Thailand. We strive to complete the process, including getting documents notarised, apostilled and translated, where required, before their photocopies can be submitted to the Thailand Embassy in London. We can also arrange to send your legalised documents back to you via a courier.


The legalisation of various types of documents issued in the UK is required for the submission or presentation in Thailand for work or business visas, or for educational purposes. The apostille certification alone will not suffice, since Thailand is not a member of The Hague Apostille Convention of 1961, which abolished the need for consular legalisation of documents.

Documents such as proof of identity (eg: passport), educational documents, health certificates and police certificates for criminal record need to be apostilled by the FCO UK before they can be submitted to the Thailand Embassy in London for legalisation. In some cases, the documents may need to be translated into the Thai language and certified and attested by a Notary Public or a Solicitor.
