Thai banks, Land Offices and share registrars require a court order appointing an estate administrator before releasing assets. This page sets out the documents the court expects, who is disqualified from acting, and where petitions commonly stall.

On death the estate vests in the heirs immediately under section 1599, but to deal with individual assets — closing bank accounts, transferring land, re-registering shares — institutions require clear proof of authority. In practice this means petitioning the court for an order appointing an estate administrator under sections 1711 to 1713, which proceeds as a non-contentious case where all heirs consent.

The competent court is the one for the deceased's domicile at death; where the deceased was domiciled abroad, the court where the estate assets are located is considered. The petitioner is typically an heir, an interested party or the person nominated in the will. The petition must set out the relationship to the deceased, a summary of estate assets, the practical obstacle to administration and the request for appointment.

Section 1718 disqualifies certain persons from acting as administrator: minors, persons of unsound mind or adjudged quasi-incompetent, and undischarged bankrupts. Check this before filing, because a disqualified petitioner will see the petition dismissed and the whole process restarted.

The document that most often delays matters is the consent of heirs living abroad, which must be signed before a Thai consular officer or a notary in that country and then certified through the chain before being sent to Thailand. Start that strand in parallel with collecting Thai documents rather than at the last minute.

Once appointed, the administrator's duties run from sections 1719 to 1733: prepare an inventory of the estate, administer and distribute to the heirs according to their entitlements, and account on completion. The administrator is not the owner; using estate property for personal benefit is grounds for removal on an heir's application and can attract liability.

Frequently asked questions

Must every heir attend court?

Normally only the petitioner attends the hearing while the other heirs consent in writing, though the court may call an heir if it wants a point clarified.

Can two administrators be appointed together?

Yes, the court can appoint joint administrators. State in the petition whether they are to act jointly or severally, because banks and Land Offices follow the wording of the order strictly.

Can a foreigner be an estate administrator in Thailand?

Nothing in the law bars a foreigner. The practical questions are the disqualifications in section 1718 and the ability to attend the hearing and deal with Thai institutions.

What is the limitation period for inheritance claims?

Section 1754 sets a one-year period from when the heir knew or ought to have known of the death, and an outer limit of ten years from death. The detail varies with the type of claim, so take advice rather than letting time run.

How long does the court take?

It depends on each court's list and on how complete the file is, which varies. We do not set timeframes on the court's behalf, but the team will give a realistic estimate once we see your documents.
