Heirs abroad can appoint a representative in Thailand, but the power of attorney must state the powers precisely, be signed before an authorised certifying officer and complete the certification chain before it can be used.

An estate power of attorney must itemise the powers granted: consenting to the appointment of an administrator, collecting deposits from a named bank, signing an estate distribution agreement, or registering transfer of a specified land plot. Broad wording such as 'to do everything on my behalf' is commonly rejected, because banks and Land Offices read authority strictly.

Signing is best done before a consular officer at a Royal Thai Embassy or Consulate in the heir's country. The alternative is signing before a local notary public and then completing certification up to that country's foreign ministry and the Royal Thai Embassy or Consulate. The Thai recipient decides which route it accepts, so ask before booking the appointment.

For land matters the Department of Lands has its own power-of-attorney forms. Using the correct form reduces counter rejections: complete every field, strike through unused space to prevent later additions, and have the grantor initial every alteration.

Two attachments are indispensable: a signed true copy of the grantor's passport and a copy of the attorney's ID. Where the signature on the power does not resemble the passport signature, officials usually ask for a separate signature certification, which restarts the certification chain.

A power of attorney lapses on the grantor's death, on revocation, or when the authorised act is complete. Estate work runs for months, so scope the powers and any validity period generously and plan for a supplementary power if a step arises that the original did not cover.

Frequently asked questions

Can a foreign notary replace the Thai embassy step?

In many cases the notary route works, but it must then be certified up to that country's foreign ministry and the Royal Thai Embassy or Consulate. The Thai recipient decides, so ask first.

Will one power of attorney cover every transaction?

Usually not. Banks, Land Offices and share registrars each read the wording against their own transaction, so separate powers per institution are common.

What if the grantor dies during the process?

The power lapses immediately, and the grantor's own succession position must be reassessed before new documents are prepared.

Are witnesses required?

Department of Lands forms include witness fields that should be completed. For general powers signed before a consular officer or notary, follow that officer's requirements.

Can a scan be sent ahead?

Yes, and it is advisable so the wording can be checked before signing, but registration requires the fully certified original.
