Collaterals of the Half-Blood Law and Legal Definition

Collaterals of the half-blood are persons related to an intestate through only one common ancestor.

At common law collaterals of the half-blood were excluded from inheritance in real property. The collateral heir of the person last seized must be his next collateral kinsman of the whole blood. [Rotenbach v. Young, 119 Misc. 267 (N.Y. Sup. Ct. 1922)].

Statutes provide that collaterals of the half-blood shall inherit only half so much as those of the whole blood: but, if all the collaterals be of the half-blood, the ascending kindred, if any, shall have double portions. [Moore v. Conner, 20 S.E. 936 (Va. 1890)].
