Firm annotation
Section 1561 is part of Book 5 (Family) of the Thai Civil and Commercial Code. This entry is awaiting firm-authored commentary; the statutory text above is verbatim from the Office of the Council of State (OCS Krisdika) Thai source, with the English translation from the FAO/UN FAOLEX repository. Always rely on the Thai original for legal proceedings.
Why this matters in practice
For lawyers: Section 1561 confers a right to USE a family name; it does not itself provide any mechanism for choosing, allocating or changing one, which is governed by the Person Name Act B.E. 2505. Note also that the section's condition is that the father is not known, which is not the same test as legitimacy. For clients: your child may use the father's family name, and may use the mother's family name where the father is not known. Registering a surname, or changing one later, is done at the district office under the Person Name Act and not under this section. The Marriage Equality Act has left the position for children of same-sex married couples awaiting administrative guidance.
Legislative history
Section 1561 reflects the traditional surname rule. The Marriage Equality Act (No. 24, B.E. 2567), in force 22 Jan 2025, has created interpretive questions for children of same-sex married couples; regulatory guidance from the relevant authorities is expected to address surname allocation in such cases.
