After Thai Marriage Contracts
A post nuptial or post nuptial agreement as opposed to prenuptial agreement in Thailand is a marriage contract between spouses concerning their financial relation and their personal and/ or marital property done after marriage. A post nuptial contract is created after the official marriage registration as it refers to an agreement after marriage.
The post-nuptial concept between husband and wife is in principle NOT recognized or legally binding under Thai law. However, a prenuptial agreement or Thai prenup marriage contract made before the marriage can be altered under the section property between husband and wife in the Thailand Civil and Commercial Code during the marriage.
After the marriage a prenuptial can only be altered or canceled by a final order of a Thai Court. The Court shall in this case notify the Marriage Registrar in order to have it entered in the Marriage Register.
