Once a man and woman are legally married, it establishes a relationship between husband and wife, especially concerning property, known as marital property.
Normally, property acquired after marriage registration shall be deemed marital property. Thai Law divide marital property into 3 types as follow:
In case of doubt as to whether a property is marriage property or not, shall be presume to be marriage property.
Managing marital property in some cases require husband and wife to be joint manager, or one spouse has to obtain consent from the other. If this provision of the law is violated, the other spouse has the right to petition the court to revoke that legal transaction, unless the other party has ratified such transaction or if the transaction was conducted by a third party in good faith and for fair compensation.
Regarding inheritance, since the husband and wife jointly own marital property, each owns half, they do not have the authority to make the will more than their own share of marital property to others. If done, the inheritance will be valid only for their own portion.
