HEIR, IRREGULAR

HEIR, IRREGULAR. In Louisiana, irregular heirs are those who are neither testamentary nor legal, and who have been established by law to take the succession. See Civ. Code of Lo. art. 874. When the deceased has left neither lawful descendants nor ascendants, nor collateral relations, the law calls to his inheritance either the surviving hushand or wife, or his or her natural children, or the state. Id. art., 911. This is called an irregular succession.
