High importance

Why this matters in practice

For lawyers: a non-consenting spouse must act within one year of discovering the unauthorised act; missing the limitation period bars the voidance claim regardless of the ten-year outer limit. For clients: if you discover your spouse sold or donated marital property without your knowledge, consult a lawyer immediately — the one-year clock runs from the date you actually found out.

Legislative history

Section 1480 was consolidated from the former §§1476 and 1480 when Book 5 was revised. The Marriage Equality Act (No. 24, B.E. 2567), in force 22 Jan 2025, made gender-neutral amendments; both spouses now share identical rights to challenge or ratify such acts.

Supreme Court decisions interpreting this section

  1. Supreme Court Judgment No. 156/2561 (2018)

    A gratuitous unilateral transfer of Sin Somros to a third party is voidable; the transferee's good faith and payment of value are the decisive factors.

    One spouse's unilateral transfer of marital property to a third party as a gift — not to the other spouse — was not a disposal 'jointly' and could be challenged; the court examined whether the transferee was a bona fide party for value to determine if the transfer was protected.

  2. Supreme Court Judgment No. 4071/2558 (2015)

    Only a married person's share in a joint purchase constitutes Sin Somros; the co-owner's share is unaffected.

    Where two persons jointly purchased land during marriage, only one spouse's share was Sin Somros; the co-purchaser's share was not affected by the marital property rules and the spouse could not claim the entire parcel as marital property.
