Quick Summary

• Executor vs. Estate Administrator: In Thai law, the role is commonly called a “ผู้จัดการมรดก” (estate administrator). The court appoints the administrator, including where a Will has named an executor.
• Foreigners can serve as the administrator, and may act through a Thai lawyer in court proceedings.
• Uncontested cases can often be filed via Courts of Justice e-Filing, without attending court in person, in specified scenarios.
• The administrator’s core duties include filing the petition, identifying assets and heirs, paying debts and expenses, and distributing the estate under the Will or Thai succession rules.

Legal Bases (with official references)

1) Representation by a lawyer (can a foreign administrator use counsel)?

Thai Civil Procedure Code; Definition of “party” includes acting via an attorney.
“(11) ‘Party’ means a person who brings or is sued in a case; and for purposes of proceedings includes persons entitled to act on his/her behalf according to law or as an attorney.” (Thai text at p. 3 of PDF)

Civil Procedure Code (Official Thai PDF)

Plain English: A duly appointed Thai lawyer may file, manage, and appear in court for the foreign administrator. The court may still request the administrator or a witness to appear if evidence is needed, but routine filings and uncontested hearings can be conducted by counsel.

2) Where/how to file the petition to appoint an administrator

• Courts of Justice (COJ), e-Filing: The COJ explains that members of the public can submit an online petition for estate administration in specified circumstances (e.g., all heirs consent; or the Will names the administrator). See COJ news and COJ Civil Court pages: COJ e-Filing info (public guidance), COJ Civil Court article on e-filing petitions.

Note: The petition is generally filed in the court with jurisdiction connected to the decedent (e.g., ordinary residence at death). The court will issue an order appointing the administrator if unopposed and the papers are in order.

3) Who can apply, and the administrator’s status (Thai Civil & Commercial Code: Succession)

Thai law uses the term “ผู้จัดการมรดก” and contemplates both (i) a person named in a Will and (ii) a person appointed by the court.

• Administrator may be named in the Will or appointed by the court (ป.พ.พ. มาตรา 1711–1712).
• Heirs/Interested persons/Public Prosecutor may petition the court to appoint an administrator in specified cases (มาตรา 1713).

These provisions are standard in Thai commentaries and official discussions; for government discussion referencing Section 1713, see the Thai Senate page summarizing a succession case: Senate (senate.go.th).

Core Duties of an Estate Administrator (what the court expects)

While the Civil & Commercial Code provisions are brief, Thai authorities and court practice expect the administrator to:

1. Identify heirs and assets (including obtaining bank/land/company information).
2. Secure and preserve the estate pending distribution.
3. Pay funeral and administration expenses and the decedent’s debts before distribution.
4. Distribute the estate under the Will; or, if no Will disposes of an item, under Thai intestacy rules.
5. Report/account to heirs or the court as required.

Foreign Executors/Administrators (Practical Options)

• Act via Thai counsel: The Civil Procedure Code allows a lawyer to act for a party in court (see definition of “party” above). Your Thai lawyer can prepare and file the petition, manage communications with the court registry, and attend hearings. [CPC definition]
• e-Filing (no in-person visit in some cases): COJ’s e-Filing can be used for uncontested estate matters or where the Will already names the administrator, subject to the court’s checklist and local practice. [COJ]
• If the court needs testimony: The judge may request the administrator or a supporting witness to appear (in person or, where allowed, via remote means). Your lawyer will advise positioning of evidence so that hearings remain paper-based where possible.

Typical Documents the Court/Agencies Will Ask For

• Death certificate (Thai or foreign with proper legalization/translation).
• Will (Thai/English versions, if bilingual) and any codicils; identification of the named executor/administrator.
• Heir information and relationships (marriage/birth/divorce documents, as applicable).
• Asset evidence: bank letters, land/townhouse docs, vehicle registration, company share register/DBD info, etc.

For public-facing guidance on the online route, see the Courts of Justice e-Filing notices cited above. [COJ]

Drafting Tips for Wills that Name a Foreign Administrator

• Express power to hire Thai counsel: “My Executor may retain Thai counsel and act through agents for court filings, hearings, registrations and transfers in Thailand.”
• Scope limited to Thai assets: If you have a separate foreign Will, clarify that the Thai Will governs Thai-situs assets only.
• Company interests: If shares are held via other persons, use neutral language: “to the extent permitted by Thai law”. Prefer documenting rights in a Schedule (with DBD particulars).
