  "summary": "Tonga is a Pacific Island common-law constitutional monarchy whose family-law framework operates under the Marriage Act, the Divorce Act, the Maintenance of Deserted Wives Act, and the Family Protection Act 2013. Tonga is structurally distinctive within the Pacific cluster as the only never-colonised Pacific Island state (Protectorate status under UK 1900-1970 without formal colonisation). Parental responsibility and child custody are governed by case-law applying the welfare-of-the-child principle. The Privy Council of Tonga (Privi Kausilio 'o Tonga) is the apex appellate court for civil and criminal matters; the Court of Appeal sits beneath the Privy Council. Family-law matters are heard at first instance in the Supreme Court (Family Division) and Magistrates' Courts. Psychology profession is regulated through the Ministry of Health framework. Tonga is silent on 'parental alienation' as a statutory label; courts operate substantively under the welfare-of-the-child principle. Tonga is non-Hague Convention.",
