Is zakat obligatory on a wife's money that is deposited into her husband's bank account, and how can it be paid, given that he does not commit to it?

A wife's salary is her exclusive right, and she may dispose of it as she wishes in lawful ways. She is obligated to pay zakat on it if it reaches the nisab and a full year has passed, whether the salary is in her account or her husband's. She does not need her husband's permission or knowledge for this, as zakat is an obligation upon every Muslim who meets the conditions for its obligation. It is not permissible for the husband to dispose of his wife's money except with her permission.
