A: Yes, wife can divorce in this manner,  if she has been delegated in the nikanama (marriage contract form) the said right is called Talak-e-Tafweez (delegated powers of divorce). The husband may delegate the right to divorce while contracting marriage as per paragraph 18 of the Nikahnama, then the wife has a right to divorce, otherwise it is the exclusive right of the husband. But if wife has no such right and she wants dissolution of marriage then she can file a suit for the “Dissolution of Marriage” on the basis of Khula or seeks divorce both through intervention of the court.
