My wife wants a khula divorce and I live in Kolkata, how does this work under Muslim law?

Khula is a form of divorce initiated by the wife, where she offers to return her dower (mahr) or any other consideration to obtain release from the marriage. In Kolkata, the consent of the husband is essential for khula to be effective as a divorce, unless the court intervenes under certain circumstances. If your husband refuses to consent, you may approach the family court or the Calcutta High Court for dissolution on grounds recognised under the Dissolution of Muslim Marriages Act, 1939. The court will assess whether there is a valid ground such as cruelty, neglect, or failure to maintain. West Bengal Premises Tenancy Act 1997 may also prescribe procedural requirements for registration of the divorce with the local registrar. You should retain documentary proof of the offer and any witness testimony supporting the khula. A formal decree from the court offers better protection for your post-divorce rights including maintenance.
