Is it permissible for a father to disinherit an undutiful and thieving son, or to deduct the value of stolen goods from his share, and which is more appropriate?

The brother's behavior towards his parents is a grave act of disobedience and a great sin, one of the major sins. He must be advised and warned of the consequences of disobedience. The father does not have the right to disinherit his son after his death, and any will to that effect is void. As for dividing wealth during one's lifetime and disinheriting a child, it is permissible if there is a compelling reason, such as his impiety or his using the money for sinful acts. The money the son stole belongs to the parents, and he must return it. If he does not return it during their lifetime, it becomes a debt upon him that he is obliged to return to the heirs. The parents should pray for his guidance, for the prayer of a parent for their child is answered.
