Ruling 2741

If a person makes a will that his debts are to be paid off, that someone is to be hired to perform his lapsed prayers and fasts, and that recommended acts are to be performed on his behalf, then in the event that he does not stipulate in his will that these are to be paid from the one-third of his estate, his debts must be paid from his entire estate. If anything remains after that, one-third of it must be spent on the lapsed prayers, fasts, and the recommended acts that he had specified. In case one-third of the remaining wealth is not sufficient, then, if his heirs give permission, his wishes in his will must be executed. If they do not give permission, the lapsed prayers and fasts must be paid for from one-third of the remainder. If anything remains after that it must be used for the recommended acts that he had specified.
