Assize of mort d'ancestor

In English law, the assize of mort d'ancestor was an action brought where a plaintiff claimed the defendant had entered upon a freehold belonging to the plaintiff following the death of one of his relatives. The questions submitted to the jury were, "was A seised in his demesne as of fee on the day whereon he died?" and "Is the plaintiff his next heir?" This assize enabled the heir to obtain possession, even though some other person might have a better right to the land than the deceased.
