Rule 21 Where no legal representative

If, in any proceedings, it appears to [^f1 the judge or district judge as the case may be] that any deceased person who was interested in the matter in question has no legal personal representative, [ the judge or district judge as the case may be] may—

on such notice to such persons, if any as [ the judge or district judge as the case may be] may think fit, either specifically or generally by public advertisement, and the order made, and any order consequent thereon, shall bind the estate of the deceased person in the same manner in every respect as if a duly constituted legal personal representative of the deceased had been a party to the proceedings.
