Firm annotation

Section 1471 defines what each spouse keeps individually. Four categories: (1) pre-marriage property; (2) inheritances received during marriage (default unless will says "to both"); (3) gifts during marriage where the giver specifically said "for X only"; (4) personal-use items (clothes, professional tools). A foreigner who marries with substantial pre-marriage wealth should keep records (bank statements, property deeds, valuation certificates from before the wedding date), without proof, the §1474 presumption that contested assets are Sin Somros applies.

High importance

Why this matters in practice

For lawyers: document pre-marital asset ownership carefully (bank statements, title deeds dated before marriage) to distinguish Sin Suan Tua from Sin Somros in divorce proceedings. For clients: keep records of inheritances and gifts received during marriage; without documentation, a court will presume marital property under §1474.

Legislative history

Sin Suan Tua was introduced when Book 5 was revised in B.E. 2519, replacing the earlier concept of 'sin doem' (original property). The Marriage Equality Act (No. 24, B.E. 2567), in force 22 Jan 2025, made no substantive change to §1471 but the regime now applies equally to all spouses.

Supreme Court decisions interpreting this section

  1. Supreme Court Judgment No. 13964/2558 (2015)

    Pre-marital land is separate property, but structures built on it during marriage with marital funds are marital property if the landowner consented.

    Land held by one spouse before marriage was Sin Suan Tua under §§1471(1) and 1472; structures built on that land during marriage using marital funds were, however, marital property — where the landowner had consented to the construction, the other spouse acquired a share in those improvements.

  2. Supreme Court Judgment No. 4982/2541 (1998)

    A gift received during marriage without a written designation as marital property is automatically separate property under §1471(3).

    Land received as a gift during marriage, without any written declaration that it was to be marital property, is classified as Sin Suan Tua (separate property) under §1471(3); the donee spouse's creditors cannot levy on it as marital property.
