Louisiana (State of Louisiana / État de Louisiane)

Jurisdiction code: US-LA · Legal system: civil-law
Language(s): en, fr

Louisiana is a North American civil-law constituent state of the United States — structurally distinctive globally as the only civil-law jurisdiction in the United States (all other 49 states operate common-law systems) and as the only civil-law jurisdiction in North America aligned with French-Spanish-Roman civil-law tradition (alongside Quebec's French-civil-law and Puerto Rico's Spanish-civil-law/common-law hybrid). Louisiana's civil-law tradition derives from French colonial law (1699-1762, 1800-1803), Spanish colonial law (1762-1800), and the 1808 Digest of the Civil Laws and 1825 Civil Code modelled on the Napoleonic Code 1804. The Louisiana Civil Code (current version 1870 with extensive subsequent amendments and 1987 obligations revision) governs family law, property law, obligations, and successions in distinctively civil-law terms (community property regime instead of common-law marital property; usufruct; forced heirship in succession), distinct from the common-law framework of all 49 other states. Family-law framework operates under Louisiana Civil Code Title V (Parents and Children) Articles 215-245 and Title VIII (Tutorship) Articles 246-303, supplemented by the 1986 Children's Code. Parental authority and child custody operate under Louisiana Civil Code Articles 131-140 (Custody) and 215-245 (Parental Authority) — operating under best-interests-of-the-child standard with civil-law structural framework. The Louisiana Supreme Court is the apex appellate court for civil and criminal matters from Louisiana; final appellate jurisdiction on federal constitutional questions lies with the US Supreme Court. Louisiana is silent on 'parental alienation' as a statutory label, though Louisiana courts have considered the concept substantively in case law including Calogero v Calogero (2003) and recent appellate cases. The United States is a Hague Convention 1980 party (acceded 1 July 1988) — Louisiana Hague applicability via US federal extension.
