Answer:
(Fatwa: 1744/1295/D=1431)
The expenses of your wife and children are wajib on you not on your parents. If your parents accept this responsibility happily and you and your wife have no objection, then there is no harm. But when your wife dislikes it you can adopt any other means of livelihood for the expenses of your wife and children. If she finds it difficult to live with your parents, you can arrange separate house for her, but you should not do all these work by making your parents angry, rather you should win their consent with wisdom. Also, always take care of their happiness along with their services and obedience.
