The Expenses of Your Brother are Taken from His Share of the Estate
Question :
We are three brothers who studied in the university while our father was alive, except our youngest brother, who was in High School when our father died. Do the costs of his studies come out of his inheritance or not?"
Answer:
The studying expenses of this young man are the same as his eating, drinking, clothing and matrimonial expenses they are paid from his money, whether it be money he owned before the death of his father, or they are from his share of the estate of his father. However, if it happened that he had nothing, or his father did not leave anything, then his expenses would be the responsibility of whoever provided from him among his kin.
