Where lands are attempted to be devised to 2 or more persons, the heirs of the decedent, in severalty by a writing purporting to be a last will which, though executed by the owner of such lands in the presence of 2 or more witnesses, is inoperative and void as a will, and such persons, their heirs, executors and assigns, remain for a period of 60 years after the death of such decedent in the actual or constructive possession of the land, so purporting to be devised to them, and the writing mentions other land not purporting to be devised to them, every such person, his heirs, executors and assigns, shall be estopped from claiming any right, title or interest in any land mentioned in such writing, other than that attempted to be devised to such person in severalty. No action shall be brought by any such persons, their heirs, executors or assigns, to enforce any right or claim as heir of such decedent in the other lands mentioned in such writing.
