Mort d'ancestor
MORT D'ANCESTOR. An ancient and now almost obsolete remedy in the English law. An assize of mort d'ancestor was a writ which was sued out where, after the decease of a man's ancestor, a stranger abated, and entered into the estate. 1, Co. Litt. 159. The remedy in such case is now to bring ejectment.
