Thai Prenuptial Agreement – Void

The prenuptial agreement shall be void if:

  • – Providing a foreign law to be applicable to their relations as regard to their properties,
  • – It is not made in writing and signed by both spouses and by at least two witnesses; and
  • – Entered in the Marriage Register.

Once the spouses are married, this ante-nuptial agreement cannot be altered, except by authorization of the Court, which is notified to the Marriage Registrar. An ante-nuptial agreement will never have any effect as regards the rights of third persons acting in good faith.
