is an adopted child that never met his or her birthparents or birth family, entitled to an inheritance from a birth grand parent?

Regardless whether the child was adopted, if named in a will, in this case by a birth grandparent, is entitled to the bequest. If there was no will, then no bequest, and no right to inherit. It is strongly recommended the questioner consult with a qualified attorney in his or her area. Gerry Wendrovsky, Esq.- Upper West Side Estate Lawyerwww.upperwestsidelawyer.com
