Overview
Amendments to the Civil and Commercial Code have refined the rules governing prenuptial agreements in Thailand. While the core principle — that spouses may agree on the management of property before marriage — remains unchanged, the registration and disclosure requirements have become more structured.
What the amendments address
The updated provisions clarify three areas:
- Registration formalities: A prenuptial agreement must be registered at the time of marriage registration at the local district office. Failure to register means the agreement does not bind third parties.
- Disclosure of assets: Each party is expected to disclose their existing assets and liabilities. Incomplete disclosure can later support a challenge to the agreement's validity.
- Capacity and voluntariness: Both parties must enter the agreement freely and with full understanding. Foreign-language speakers are entitled to a certified translation of the agreement before signing.
Implications for foreign spouses
Foreign nationals marrying in Thailand should ensure that their prenuptial agreement is drafted in both Thai and their native language. A properly notarized and translated agreement reduces the risk of future disputes and is more readily recognized by courts and foreign authorities.
Drafting considerations
A well-drafted prenuptial agreement typically addresses:
- Identification of personal property brought into the marriage.
- Treatment of income and assets acquired during the marriage.
- Responsibility for existing debts.
- Governing language and applicable law, where cross-border issues arise.
