English translation

In the management of the Sin Somros which has to be made jointly or has to obtain the consent from the other spouse under Section 1476, if either spouse has entered into any juristic act alone or without consent of the other, the latter may apply in Court for revoking such juristic act, unless it has been ratified by the other spouse, or the third person was at the time of entering into such juristic act, acting in good faith and make the counter-payment. The litigation for revocation of the juristic act by the Court under paragraph one cannot be made later than one year from the day when such cause as being the ground for the revocation is known, or later than ten years since the juristic act was done.

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.

  • consent required
  • Sin Somros
  • voidable act
  • one-year limitation
  • good faith third party

Supreme Court decisions interpreting this section

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

    Where a deed records a transfer of marital property as a gift, the parties may prove by witnesses what the transaction really was, since that is proof of true intention and the origin of the contract, not evidence altering a document. If the transfer was in fact for consideration and the third party acted in good faith and paid value, the other spouse cannot have it revoked under section 1480 paragraph one.

    The plaintiff sued to revoke the registration by which defendant 1 transferred the whole disputed plot to defendant 2 as a gift. The defendants proved that defendant 1 had in fact sold it to defendant 2 for 400,000 baht but declared it a gift to reduce the fees. The Court held they were entitled to prove the true intention behind the transaction and the origin of the contract, which was not evidence altering a document prohibited by Civil Procedure Code section 94(b). The transfer was therefore one for consideration, and since defendant 2 was a third party who acted in good faith and paid value, the plaintiff could not have it revoked under section 1480 paragraph one.

  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.
