Thailand's Hague status & what it means
Thailand will become a member of the Hague Apostille Convention on 28 February 2027, but until then an apostille from the UK will not be accepted for use there. Before that date, any paper you need to use in Thailand must go through the longer process called embassy or consular legalisation instead. This legalisation route is managed by the Royal Thai Embassy in London.
Apostille vs. Embassy legalisation for Thailand
Until the Hague Convention takes effect in Thailand in 2027, documents need consular legalisation rather than an apostille. This involves more steps and takes longer. You will need a certified copy of your original civil record, which you can get from Leicester Registration Service at 115 Charles Street, followed by multiple stamps from authorities in a set order. The full cycle of document legalisation for Thailand requires careful planning to meet local rules.
The Leicester → Thailand route step by step
Start by getting a certified copy of your original paper from Leicester Registration Service; never send your only original document through the post. The certified copy can be sent for the rest of the process. For an apostille issued in Leicester for use in Thailand after 2027, you would send it to the FCDO Legalisation Office at PO Box 6255 in Milton Keynes. Until then, that same copy must go to the Legalisation Office, then to the Foreign Office, and finally to the Thai Embassy in London for consular legalisation.
After the embassy stamps, you can send the legalised copy to Thailand. Note that an apostille from United Kingdom to Thailand is not valid until February 2027. Until then, only the consular-legalised paper with both UK and Thai embassy stamps will be accepted by authorities there. Always order an extra copy of your civil record and keep it safe as your personal record.
What you need for an apostille for Thailand
The core is a certified copy of your original document, which you get from Leicester Registration Service at 115 Charles Street. You must decide who will handle the process after that: you can do it through postal services or use an agent who knows the embassy steps. The certified copy will need to be accompanied by the right forms from the FCDO Legalisation Office.
You can get an apostille for Thailand after February 2027, but for now, consular legalisation is required. The embassy in London will stamp your paper once it has been through all the UK government steps. Since the process takes several weeks, most people use a reliable courier to move the papers between offices. Remember that some Thai agencies may have their own rules, so show them your document early to confirm it meets their needs.
