Sin Somros vs Sin Suan Tua — Presumption and Burden of Proof
Spouse Claiming Personal Property v Spouse Claiming Marital Share
Composite summary — not a single reported case. This entry distils a settled line of Thai Supreme Court (Dika / ฎีกา) authority for legal education. It is not a transcript of one reported judgment, and the heading is not a citable case number. Do not cite it as specific case law — consult a Thai-qualified lawyer for the authoritative Dika number and current application.
Facts
On divorce or death, one spouse claimed that a particular asset — typically land, a vehicle, savings, or business shares acquired during the marriage — was sin suan tua (personal property) because it derived from pre-marital savings, gift, or inheritance. The other spouse claimed sin somros (marital property) status, with a default 50/50 division on dissolution.
Legal Issue
How the statutory presumption of sin somros operates for assets acquired during marriage, and what evidence is needed to displace it.
Holding
The Supreme Court has consistently held that, under Section 1474 CCC, property acquired during the marriage is presumed to be sin somros. A spouse alleging sin suan tua status bears the burden of clear and convincing proof — tracing the asset to pre-marital funds, gift, inheritance, or compensation for personal injury (Section 1471). Mixing of personal and marital funds tends to convert the whole to sin somros unless tracing is precise.
Reasoning
Section 1474 reflects the public policy that marriage is an economic partnership; the default is community of acquests. The presumption protects the spouse who, in practice, often had no documentary trail (frequently the wife in older cases). Strict tracing prevents the wealthier or more-documented spouse from claiming everything as personal.
Significance
Central to every Thai divorce settlement and to estate planning for married couples — particularly mixed-nationality couples and entrepreneurs.
Practical Takeaway
Keep clear separate accounts and contemporaneous documentation for any pre-marital, gifted, or inherited assets. For mixed-nationality couples, accept that the default presumption favours equal sharing unless paperwork proves otherwise.
