Marital home, but is it a marital asset?
Home ownership registration on your Thai spouse's name
When a Thai national married to a foreigner requests ownership registration of land in Thailand the Land Department must insure that the land becomes a personal (non-marital) asset of the Thai spouse only. The reason is because foreigners are not allowed to own land in Thailand, not even as a jointly owned marital property. The Land Department will ask from the foreign and Thai spouse a joint declaration that the money expended on the land (or land and house) belongs to the Thai spouse's personal assets (Sin Suan Tua), and therefore (under Thai laws governing property of husband and wife) will remain a personal (non-marital) asset of the Thai spouse (pursuant to section 1472 Civil and Commercial Code).
