  "summary": "Guam (Guåhan) is a Pacific Island common-law unincorporated US territory — structurally distinctive as the largest US territory in the Mariana Islands archipelago and the location of substantial US military presence. Family-law framework operates under the Guam Code Annotated Title 19 (Personal Relations) drawing on US-derivative common-law substantive heritage. Parental responsibility and child custody are governed by Guam Code Annotated Title 19 Chapter 3 (Family Court). The Supreme Court of Guam is the apex domestic court for civil and criminal matters; appellate jurisdiction in certain federal questions lies with the US Court of Appeals for the Ninth Circuit. Family-law matters are heard at first instance in the Superior Court of Guam (Family Court Division). Psychology profession is regulated through the Guam Board of Allied Health Examiners. Guam is silent on 'parental alienation' as a statutory label; courts operate substantively under the welfare-of-the-child principle. Guam is a Hague Convention 1980 party via US territorial extension effective 1 July 1988. Guam has substantial Chamorro indigenous cultural heritage retained alongside US civic framework.",
