When a person passes away, all assets, liabilities, and legal rights become part of the estate. To properly manage, distribute, and settle these matters, it is often necessary to appoint an estate administrator (also known as an executor or administrator).
If no executor is named in a will, or if the heirs cannot agree, a petition must be filed with the Thai court to appoint an estate administrator.

What Does an Estate Administrator Do?
An estate administrator is responsible for managing the deceased’s estate, including:
- Collecting and identifying all assets
- Settling debts and obligations
- Managing or disposing of estate property
- Distributing the estate to heirs in accordance with the law or the will
Who Can File the Petition?
The following persons may file a petition with the court:
- Statutory heirs
- Beneficiaries under a will
- Any interested person with a legal interest in the estate
The court will consider the suitability of the applicant before making an appointment.
Required Documents
Typical documents required include:
- Death certificate of the deceased
- House registration of the deceased

Additional documents may be required depending on the case.
Procedure for Filing the Petition
- Prepare the petition and supporting documents
- File the petition with the competent court
(usually the court where the deceased had their last domicile) - Court schedules a hearing
