Understanding how marital property is defined and managed in Thailand is essential for protecting your rights during marriage or divorce. Thai law distinguishes between Sin Somros (marital property) and Sin Suan Tua (personal property), each with its own rules on ownership, management, and liability. Knowing these differences helps couples make informed decisions about assets, debts, and legal responsibilities throughout their marriage.
Each spouse manages his or her own Sin Suan Tua (non-marital property). This includes:
Sin Somros refers to the property jointly owned by both spouses. It includes:
Management of Sin Somros
Both spouses must act as joint managers—or one must obtain the other’s consent—when dealing with the following matters:
In all other matters not listed above, either spouse may manage the Sin Somros independently without the consent of the other.
If the managing spouse commits, or is about to commit, any act in managing the Sin Somros (marital property) that may cause undue loss, the other spouse may apply to the court for an order prohibiting such act.
If either spouse is personally liable for any debts incurred before or during the marriage, that spouse must use his or her Sin Suan Tua (personal property) to fulfill the obligation, either in part or in full. If the debt is not fully paid, the remaining balance must be settled using his or her portion of the Sin Somros (marital property).
When both spouses are jointly liable for a debt, payment shall come from the Sin Somros and, if necessary, from each spouse’s Sin Suan Tua.
Joint debts include those incurred by either spouse during the marriage for:
If either spouse is declared bankrupt, the Sin Somros shall be divided by operation of law from the date of adjudication.
In summary: Both spouses share responsibility for debts related to family expenses, marital property, and joint business matters, while personal debts remain the liability of the individual spouse.
