Wills and estate administration documents

Drafting wills, mapping estate assets, and preparing petitions to appoint an estate administrator, including cross-border assets and heirs. It sits within family, marriage and personal status, so it can be planned alongside related work without duplicating filings.

People holding assets in Thailand and abroad, and heirs administering an estate. If you are unsure whether your case qualifies, share the documents and the receiving authority so the scope can be assessed first.

Normally: Testator’s ID card and house registration · Asset schedule with title documents · Records evidencing heir relationships, such as birth or marriage registration · Death certificate, where an administrator is being appointed. The receiving authority may require additional items.

1) Build the asset schedule and identify beneficiaries precisely 2) Choose a valid will format and complete every statutory element 3) Execute before witnesses as the law requires 4) For administration, petition the court to appoint an administrator with heir evidence 5) Translate and legalise estate documents where assets or heirs are overseas

Civil or provincial court for the administrator petition is the primary authority. Business services in Thailand map onto clearly separated authorities: company registration sits with the Department of Business Development, taxation with the Revenue Department, social security with the Social Security Office, certification of translations for overseas use with the Department of Consular Affairs (MFA), and signature certification with lawyers authorised under Lawyers Council regulations. Routing each task to the correct authority from the start is what prevents re-filing and rejection.

Send the documents you hold, the intended use, and the receiving authority or destination country. We assess scope, flag missing items and propose a filing order that reduces rejection risk. Available in Bangkok, Khon Kaen, Udon Thani, Nong Khai and online nationwide.
