Are the costs of a child's study abroad deducted from their inheritance share?

The sums you paid for your son's university education: Either they were a gift, in which case you are not permitted to revoke it because it has been consumed. Or they were a loan, in which case you are permitted to demand its repayment during your lifetime, and after your death, it is added to the inheritance, and the heirs are given the choice between forgiving it or deducting it from his share of the inheritance. Justice must be observed in giving gifts among children, and there is no harm in singling out one of them for an increase due to need or engagement in seeking knowledge.
