Practice area
Family & Succession
Marriage, divorce, custody, wills and estate administration
Family and succession work handled with both legal and personal care: cross-border marriage registration, prenuptial agreements, divorce, custody, adoption, wills and appointment of estate administrators.
What this practice covers
- Thai-foreign marriage registration and embassy affirmations
- Prenuptial agreements and marital property arrangements
- Administrative divorce and divorce by court judgment
- Custody, child maintenance and legitimation
- Domestic and inter-country adoption
- Wills, estate administrators and distribution including overseas assets
How we work on your matter
- 1Understand the family situation and the client’s goals
- 2Verify legal status and civil-registration documents
- 3Present the least adversarial workable option first
- 4Prepare documents, with translation and legalisation for cross-border matters
- 5File with the district office, embassy or Juvenile and Family Court
Documents to prepare
- ID card and house registration, or passport
- Affirmation of freedom to marry from the embassy for a foreign spouse
- Marriage, divorce or death certificates as relevant
- Children’s birth certificates for custody and maintenance matters
- Schedule of estate assets and ownership documents
Points to watch
- Foreign documents must be translated and legalised before the district office appointment or they will be refused.
- A prenuptial agreement must be recorded at the time of marriage registration; it cannot be added later.
- A will that fails the statutory formalities is void, however clear the intention.
Typical timeframe
Marriage registration completes in one appointment when documents are ready; contested divorce or succession cases take many months or longer.
Timeframes are indicative only and depend on the authority, the court calendar and the completeness of your documents.

Example situations and how they are handled
These are constructed examples used to explain procedure. They are not client matters, and no outcome is implied or guaranteed.
Illustrative scenario: consensual divorce with a foreign spouse
Situation: Both parties agree to divorce but need the outcome recognised abroad.
Usual approach: Plan documents from the start: child and property terms, registration of the divorce, and certification/translation for overseas use. (Hypothetical.)
Advice for your specific situation
Spouses with children
- Spell out custody, residence, contact and maintenance to reduce later disputes.
- Agreements not properly registered or formalised can be hard to enforce.
Foreigners married in Thailand
- Check how your home country recognises a Thai marriage or divorce and what certification it requires.
- Marital status affects visas and residence — plan both together.
Every matter — what to do in the first 7 days
- Gather every original document in one place, keep scanned copies, and note the date you received each one.
- Write a dated timeline — the date you received a notice or learned of the event usually starts the limitation or appeal clock.
- Do not sign a settlement, debt acknowledgement or withdrawal before a lawyer reviews it — it may extinguish existing rights.
- Preserve digital evidence unaltered (full screenshots, original files, emails with headers) — edited files are easy to challenge.

Frequently asked questions
What must a foreign spouse prepare before registering a marriage?
Usually an affirmation of freedom to marry from their embassy, translated into Thai and legalised at the Department of Consular Affairs before filing at the district office.
How does administrative divorce differ from court divorce?
Administrative divorce requires mutual consent and a Thai-registered marriage; otherwise the matter goes to the Juvenile and Family Court.
