MFA, embassy and Apostille chain

Usually you sign the Department of Lands mandate before an officer of the Royal Thai Embassy or Consulate-General where you live, so your signature is certified, then courier the original to your attorney-in-fact to file at the land office. If you sign before a local notary instead, the document must be legalised in the chain used by that country, translated into Thai, and the translation certified by the Department of Consular Affairs. Ask the specific land office in advance — practice varies.

Mostly no. Banks keep their own mandate forms and usually require signing in front of branch staff, or signature certification by a Royal Thai Embassy if you are abroad. Call the branch that holds the account first and ask which form, how many witnesses, and which certification routes they accept before preparing anything.

Petitions are filed by a lawyer. An heir abroad can sign the power of attorney to the lawyer and the heirs' letter of consent before a Royal Thai Embassy or Consulate officer and courier the originals for filing. Some courts still want the heir to testify in person or by video conference, so plan for that possibility.

Sign before a notary public in the country of residence, then follow that country's chain — an Apostille if it is a convention party, otherwise foreign-ministry legalisation followed by Royal Thai Embassy certification — then have the document translated into Thai with the translation certified by the Department of Consular Affairs before filing in Thailand.

The non-travelling parent should state the child's name, passport number, destination, travel dates, who will accompany the child, and contact details, and sign before a Notarial Services Attorney in Thailand or a Royal Thai Embassy officer abroad. Some destinations also want the letter translated into their language and legalised.

For applicants under 20 the Department of Consular Affairs requires the persons with parental authority to attend or to provide a consent letter with a properly certified signature. If one parent is abroad, that consent is signed before a Royal Thai Embassy or Consulate officer. Check the current document list at consular.mfa.go.th before booking.

A consensual divorce registration normally requires both spouses to appear at the district registrar. The Department of Provincial Administration has procedures for cross-registrar divorces and for a spouse who is overseas, handled through a Royal Thai Embassy — not by authorising a third party to sign instead. Ask the district office where you intend to file before preparing documents.

Thailand has no common-law notary public. The equivalent function is performed by a Notarial Services Attorney registered with the Lawyers Council of Thailand. In addition, consular officers of the destination country's embassy in Thailand can certify signatures for documents to be used in their own country.

Signature certification confirms that the named person signed in the certifier's presence after showing identification. Translation certification confirms the translation matches the original. They are separate steps and usually run in sequence. The Department of Consular Affairs certifies translations and, for certain documents, signatures of authorised officials — it does not replace the Notarial Services Attorney step.

Usually four: signing before a Notarial Services Attorney, translation into the destination language where needed, certification by the Legalisation Division of the Department of Consular Affairs, and legalisation at the destination country's embassy in Thailand. The chain shortens for convention parties once the Apostille Convention enters into force for Thailand on 28 February 2027.

A private document needs a traceable signature first, so it normally goes through signature certification by a Notarial Services Attorney before the consular step. Check the accepted document types and appointment process at consular.mfa.go.th.

From 28 February 2027, documents for use in another convention party will end at the Apostille certificate issued by Thailand's competent authority, with no destination-embassy step. Non-party states, including some Gulf countries, keep the existing chain. Before that date the current chain still applies to everything.

Generally no. It must be legalised in the country of origin, certified by the Royal Thai Embassy there, then translated into Thai with the translation certified by the Department of Consular Affairs before a land office, bank, court or other Thai authority will accept it. Allow several weeks overall, depending on each queue.

Yes. An Apostille authenticates the origin of a signature and seal; it does not certify content and does not make the document Thai. Thai authorities still want a Thai translation certified by the Department of Consular Affairs, and the translation must cover the body, the seals, and the Apostille certificate itself.

The sequence Thai authorities expect is: sign before a notary public or a Thai consular officer abroad, have the competent authority of that country certify the notary's signature, then have the Thai embassy or consulate legalise it. Once in Thailand the document is translated into Thai by a translator who states their name and contact details, and the translation is certified by the Legalisation Division of the Department of Consular Affairs before it is shown to the land registrar. When the Apostille Convention enters into force for Thailand on 28 February 2027, an apostille from a member state replaces the embassy step, but the translation and translation-certification steps remain.

Usually not. Banks apply their own mandate forms under know-your-customer and anti-money-laundering rules. The workable path is to contact the account-holding branch in advance for its specific form, have the account holder sign it before a notary abroad, legalise it through the embassy route (or by apostille once the convention applies), and courier the original back. Some banks add a video identity check.

Besides the mandate itself: a certificate of incorporation issued within the last six months, the list of directors, and a board resolution approving the delegation. The whole bundle is legalised abroad by the same route as the mandate, translated into Thai and the translation certified by the Department of Consular Affairs, before filing with the Department of Business Development or another receiving authority.

A petition to appoint an estate administrator must come from an heir or an interested person, but an heir abroad can authorise a lawyer to file and conduct the proceedings, together with consent letters from the other heirs. Documents signed abroad follow the usual legalisation and translation route. Transfers after the court order are then carried out by the court-appointed administrator.

From 28 February 2027 public documents issued in a member state will carry a single apostille instead of chained legalisation at a Thai mission, which shortens the timeline considerably. Three things do not change: the notarial certification of the signature comes first, a certified Thai translation is still needed, and the content must still match what the receiving authority requires. Until then, use the embassy route.

Not immediately in most cases. The signature is normally certified by a notary public or a Thai consular officer abroad, then the document is translated into Thai and legalized by the Legalization Division of the Department of Consular Affairs before it is presented to the Land Office. For sale or mortgage transactions officers usually expect wording that matches the official Tor Dor 21 form and an exact title deed number. Confirm the document list with the specific district Land Office before shipping papers internationally, because local practice varies.

The Apostille Convention enters into force for Thailand on 28 February 2027. After that date documents issued in member states carry a single Apostille certificate instead of multiple embassy legalization layers, which shortens the chain and makes timing more predictable. Thai translation and wording review remain necessary because the receiving authority still reads the Thai text. For documents prepared before that date, ask the receiving office whether the earlier format is still accepted.

Each bank sets its own form and conditions, and many accept only their own document signed in front of staff. When the principal is abroad, the usual route is to sign before a Thai consular officer or a notary public, then have the document translated into Thai and legalized at the Department of Consular Affairs before filing. Prepare identification for both parties, the account details and a power of attorney with a clearly limited scope. Overly broad authority is frequently refused, so ask the branch that holds the account before drafting.

Evidence that the signatory can bind the company: a recent certificate of incorporation or company extract, the board resolution or minutes approving the appointment, and specimen signatures. The signature is notarized in the issuing country, authenticated by the local authority and the Royal Thai Embassy, then translated into Thai and legalized in Bangkok. Ensure the company name and registration number match on every document, and that the resolution is dated no later than the power of attorney itself.

According to HCCH, the 1961 Apostille Convention enters into force for Thailand on 28 February 2027, which will let documents moving between member states rely on a single apostille certificate instead of a multi-layer chain in many cases. Until then the existing route applies: certification at source, embassy authentication, then legalization in Thailand. Non-member countries will keep the old chain, and Thai receiving offices will still normally require a certified Thai translation. Confirm current practice with the Department of Consular Affairs before you start.

Land Office registrations use the Department of Lands' own power of attorney form, not a general POA. Prepare the completed form with no blank spaces, the original title deed, ID or passport and house registration of both principal and attorney, with certified copies. State exactly what is delegated — sale, mortgage or transfer of a specific plot — sign before two witnesses, and if signed abroad, have it notarised, legalised by the Thai embassy and certified by the Department of Consular Affairs. The most common causes of rejection are blank spaces left in the form, a wrong title deed number, or a name spelt differently from the deed. We check the form and the certification chain before filing.

The standard sequence is: draft to the receiving country's requirements, sign before a Notarial Services Attorney registered with the Lawyers Council of Thailand, obtain legalisation from the Department of Consular Affairs (Legalisation Division), then, if still required, certification by that country's embassy in Thailand. Countries in the Apostille Convention accept an apostille instead of embassy legalisation only when the issuing country is also a party; Thailand's accession is still in progress, so the two-step legalisation route remains the norm. Ask the receiving party for their requirements in writing before you start so nothing has to be redone.

Prepare a written revocation identifying the original document by date or reference, the parties, and the effective date. Have it certified by a Notarial Services Attorney, then processed by the Department of Consular Affairs and the destination channel used for the original. Critically, notify every party holding the original, such as the bank, the foreign lawyer, or the land registry, because revocation affects third parties from the time they receive notice.

Sign before a notary public or a Thai embassy officer in that country. If the country is a Hague Apostille party, obtain an apostille from its competent authority; if not, obtain foreign ministry certification followed by Thai embassy legalization. Once in Thailand the document is translated into Thai and the translation certified by the Department of Consular Affairs before submission. Total time depends on each authority's queue.
