Does wills covering assets in more than one country require additional translation or certification?

Short answer

Marriage, divorce, legitimation and succession are all registered or adjudicated events with formal requirements. Where one spouse is a foreign national, the receiving country's rules matter as much as the Thai ones, so documents are usually translated and legalised before they are accepted abroad.

How this case runs end to end

Confirm marital and parental status from official records, prepare the agreement or petition, register at the district office where registration is possible, apply to the court where the matter requires a judgment, then translate and legalise the resulting record for use abroad.

What to prepare

  • Passports or Thai ID cards of every party, plus company affidavits where a company is involved
  • The underlying documents: draft contract, title deed, register extract or court papers
  • The deadline or hearing date that governs the matter
  • Evidence of authority to sign: board resolution, power of attorney or shareholder approval
  • Certified translations where a document is not in Thai and will be filed with a Thai authority
  • Correspondence already exchanged with the counterparty or the authority
  • A single contact person who can confirm instructions and receive filings

What "Does wills covering assets in more than one country require additional translation or certification?" actually involves

This question sits within family law, matrimonial property and succession. The authority or standard that governs it directly is the Civil and Commercial Code Books 5 and 6, district registrars and the Central Juvenile and Family Court, and every case is assessed against the rules in force on the day of submission. IVC prepares the file, checks internal consistency and coordinates with the receiving office; we are not a government body and we never guarantee how an authority will decide.

Divorce by mutual consent is registered at a district office only if both spouses attend and the marriage was registered in Thailand.

An estate administrator is appointed by court order; banks and the Land Office ask for that order rather than for a will alone.

A prenuptial agreement must be registered together with the marriage; one signed afterwards does not have the same effect.

Rules and requirements to settle before you start

A father who was not married to the mother acquires parental power through legitimation, by registration or by court order.

A will limited to Thai assets should say so, to avoid revoking a will made in another country by implication.

Changes to directors, shareholding, capital or objectives must be registered within the statutory period, and a late filing is visible on the public record.

Nominee shareholding arrangements are prohibited and carry criminal liability for both the Thai and the foreign participants.

The mistakes that cost the most time

The costliest pattern in legal matters is signing first and asking afterwards. A contract, a deed or a resolution creates obligations from the moment of signature, and undoing one usually costs more than the review that would have prevented it — particularly where a registration has already been made against a title or the public record.

The second is treating deadlines as administrative rather than substantive. Prescription periods, appeal windows, licence renewals and registration periods are hard cut-offs; once one passes, the strength of the underlying position becomes irrelevant and the remaining options are far narrower and far more expensive.

Why files are delayed or returned

  • The prenuptial agreement was not registered with the marriage
  • One spouse cannot attend the consensual divorce registration
  • The estate is dealt with without a court appointment of an administrator
  • Foreign documents are filed without certified translation and legalisation
  • Board or shareholder approval is missing for a resolution being registered
  • A capital increase is paid in without the required evidence of remittance
