Thailand acceded to the 1961 Hague Apostille Convention on 30 June 2026; it enters into force for Thailand on 28 February 2027, so Apostilles are not yet issued. Thai documents are legalised at the Department of Consular Affairs, Ministry of Foreign Affairs, and then at the destination country mission where that country requires it.
Clients in Bangkok can walk in at Bangkok Headquarters (Lat Phrao 95).
Bangkok hosts almost every embassy accredited to Thailand, and the Department of Consular Affairs, which legalises documents, sits on Chaeng Watthana Road in Lak Si. Clients in the capital can therefore usually finish all three stages in one city: notarial attestation by a Notarial Services Attorney, translation, and legalisation at the Ministry of Foreign Affairs or the relevant embassy. What slows Bangkok files down is rarely distance; it is appointment queues and cross-town travel at rush hour, so the order in which you visit each office matters more here than elsewhere.
Our head office is on Lat Phrao 95, so documents can be signed in person there. Before any government visit we tell you which steps you must attend yourself and which can be done under a power of attorney, because some embassies insist that the applicant appears in person. Building the plan around those fixed appearances is usually what saves the most time in Bangkok.
Many Bangkok clients use the same document set with several authorities, for example an affidavit of single status at an embassy and then at a district office for marriage registration. Tell us at the start every place the document will be used. We can then prepare enough originals and certified copies in a single round, instead of reopening the file after the first authority keeps the only original. If you are working to an embassy appointment date, send us that date too, so the attestation and translation are finished with a margin before you queue.

The steps below are drawn from the procedures the responsible authority publishes itself, with the source and verification date shown. Some steps depend on the case and may change with the authority’s own announcements. Department of Consular Affairs, Ministry of Foreign Affairs · 2026-08-10
The destination country is not a party to the Apostille Convention
If the destination is not a party, the document needs consular legalization plus destination-embassy certification instead, so an apostille will not serve. Check the destination’s status before filing.
Filing a copy the issuing office has not certified
The officer must verify the issuing authority’s signature and seal; a self-made photocopy provides nothing verifiable. Obtain a certified true copy from the issuing office first.
The translation omits parts of the document
Seals, signatures and end-notes form part of the original. A translation that drops them is treated as not matching the original and must be corrected before re-filing.
Incomplete authority for the person filing
When not filing in person, a power of attorney with a copy of the grantor’s ID is required, and its scope must cover the specific filing.

In most cases no. Filings with central authorities such as the Department of Consular Affairs or an embassy can be handled on your behalf. Steps that legally require you in person — fingerprinting, or signing in front of the certifying attorney — cannot be delegated.
Turnaround depends on the responsible authority’s queue and rules at the time, so we publish no fixed figure. We tell you the authority’s own published window on the day you ask, plus the steps that usually cause delay.
Our team can review documents and coordinate translation, signature certification, legalisation and embassy steps within the agreed scope. Some steps may still require the document owner to appear or sign in person under the receiving authority’s rules.
We do not publish fixed prices: official fees, page counts and language pairs differ in every case. Send the document details and destination and we will scope the work and cost for your specific case.
Documents can travel by trackable EMS or private courier. Confirm the recipient, address and original-document handling before dispatch; the coordinating destination is Bangkok Headquarters (Lat Phrao 95).
Send the document details and the destination that will receive it. We map the correct chain before starting, flag what usually gets rejected, and run it end to end — as advisers, not just a filing agent.
