  "summary": "Thailand is a Southeast Asian civil-law constitutional monarchy whose family-law framework operates under the Civil and Commercial Code (CCC) Book 5 (Family). Parental power (อำนาจปกครอง / amnaj pokkrong) is governed by CCC arts. 1566-1598/14; joint exercise during marriage is the statutory default. The Supreme Court (Sandika Suprim / ศาลฎีกา) is the apex court for civil and criminal matters; the Constitutional Court (ศาลรัฐธรรมนูญ) operates separate constitutional-review jurisdiction. Specialised Juvenile and Family Courts (ศาลเยาวชนและครอบครัว) operate at first instance for family-law matters under the Juvenile and Family Court and Procedure Act 2010. Psychology profession is regulated through Ministry of Public Health licensing under the Mental Health Act 2008 framework. Thailand is silent on 'parental alienation' as a statutory label; courts operate substantively under the welfare-of-the-child standard. Thailand acceded to the Hague Convention 1980 effective 1 November 2002.",
