Binding effect of approval by Court
70Where a personal representative has filed in the Court an account of his dealings with the estate, and the Court has approved thereof in whole or in part, and he is subsequently required to pass his accounts in the Court of King’s Bench, such approval, except so far as mistake or fraud is shown, is binding upon any person who was notified of the proceedings taken before the Court or who was present or represented thereat, and upon everyone claiming under any such person.
