  "summary": "Jersey is a Western European mixed-legal-system Crown Dependency — structurally distinctive globally as a Bailiwick combining Norman customary-law substantive heritage (via 1204 retention by King John when Normandy lost to France) with English common-law procedural inheritance. Jersey law retains substantial Norman customary-law foundations and Latin/Old French legal terminology. Family-law framework operates under the Matrimonial Causes (Jersey) Law 1949, the Children (Jersey) Law 2002 (drawing on English Children Act 1989 model), and customary-law inheritance via the Royal Court of Jersey. Parental responsibility and child custody are governed by Children Law 2002 Part II. The Court of Appeal of Jersey is the apex domestic appellate court; final appellate jurisdiction was retained with the Judicial Committee of the Privy Council in London. Family-law matters are heard at first instance in the Royal Court of Jersey (Family Division) and the Petty Debts Court. Psychology profession is regulated through the Jersey Health and Social Care framework. Jersey is silent on 'parental alienation' as a statutory label; courts operate substantively under the welfare-of-the-child principle codified in Children Law 2002 art. 2. Jersey is a Hague Convention 1980 party via UK territorial extension effective 1 August 1986.",
