Haeres Natus Law and Legal Definition

Haeres natus is an heir born; the heir at law. Haeres natus is distinguished from haeres factus who is a created heir or an heir appointed by will, or a testamentary heir.

“If a testator declares that the haeres factus of his will shall be the same as the law would designate as his haeres natus, if he had died intestate, there can be no ambiguity to be explained by parol testimony.” [Aspden's Estate, 2 F. Cas. 37, 59 (C.C.E.D. Pa. 1853)].
