Is it permissible for me to agree with my wife to cut off ties with her family, who interfere in our marital life, especially after they disposed of her money without her permission?

The interference of the wife's family in ruining the relationship between the spouses is a transgression. The spouses should exercise wisdom, understanding, patience, and prayer, and gently advise the wife's family. The disposal of the wife's property by her family without her permission is an objectionable act that must be rectified. The wife should not cut ties with her family, even if they mistreat her, because they have a right to kinship ties, though it is permissible to avoid them to prevent harm.
