In Liggett v. Rohr, 122 W. Va. 166, 7 S.E.2d 867 (1940), an instrument in the form of a land grant by parents to their children was properly executed and delivered. It contained, however, a provision that it was not to take effect until the mother's death. Finding that a conditional deed is still deemed a valid immediate transfer, the Court held that the children were "vested with an immediate estate." Id. at 169, 7 S.E.2d at 869.
