(b) The personal representative at any time may pay any just claim that has not been barred, with or without formal presentation, but the personal representative is personally liable to any other claimant whose claim is allowed and who is injured by such payment if
- (1) the payment was made before the expiration of the time limit stated in (a) of this section and the personal representative failed to require the payee to give adequate security for the refund of any of the payment necessary to pay other claimants; or
- (2) the payment was made, due to the negligence or wilful fault of the personal representative, in such a manner as to deprive the injured claimant of priority.
