Book excerpt: Family Law in Louisiana is designed for use in law school courses that involve the study of the distinctive family law of Louisiana, a law that represents a unique blend of Continental ("civilian"), Anglo-American, and autochthonic legal principles. Topics covered include those that would be covered in a standard textbook on American family law, including prerequisites for and the nullity of marriage; the dissolution of marriage; the incidents of divorce, such as interspousal alimony, child custody, and child support; filiation (paternity); parental responsibility and authority; care for children outside of marriage (tutorship); care for incapacitated adults (curatorship); choice of law; and constitutional constraints on state regulation of family relations.
