Given below are the provisions for divorce to a marriage under Muslim law, when initiated by the wife.
Khula
Khula is divorce initiated by the wife. If you want to divorce your husband, you can go to either the court directly or to a Mufti. The Court or the Mufti will ask the husband to be present. And in the presence of the husband the court or mufti will ask the husband if he accepts the offer. Once the husband accepts the offer, the divorce is complete.
Talaq-e-tafwid
Your husband has the power to delegate or transfer his right to divorce, to you or any third person through the contract of marriage (kabi-nama) at the time of the marriage. This agreement lists down important points for such transfer of right.
It usually stipulates the amount of mehr you have to forgo to exercise your right to ask for a divorce.
