Yes, since 1999! Prior to 1998, any Thai woman who married a foreigner would lose her right to purchase land in Thailand. She could, however, still retain land that she owned prior to marrying the foreigner. However, the recent Ministerial regulation from 1999 now allows Thai national’s married to foreigners the right to purchase land, but the Thai spouse must prove that the money used in the purchase of freehold land is legally solely theirs with no foreign claim to it. This is usually achieved by the foreign spouse signing a declaration stating that the funds used for the purchase of property belonged to the Thai spouse prior to the marriage and are beyond his claim.
