Any Alims here??

Islamically or legally by the country you live in?????? Both have different implications. Khula is initiated by the wife. It means to ask for a dissolution of the marriage, in which case, she's forgoes the Mahr gift. In legal terms you need to see what are the terms and conditions of a dissolution. Islamically ofcourse you will need a person who is legislated by the State to perform marriage contracts on the basis of religion. Only he can perform the dissolution religiously but still not legally. Court proceedings must be completed.
