The prospective second wife lives in another state — where must I apply?

An application for polygyny permission is usually made at the Syariah Court of the state where the husband resides. The prospective wife, for her part, must follow the procedure for permission to marry in the state where she resides. In practice, a cross-state marriage involves two religious affairs offices: the man's office issues permission or confirmation, while the woman's office handles the akad and registration. Both will ask for a copy of the polygyny permission order. Exact requirements vary between states, so contact both district religious affairs offices before setting the date of the akad. See the state-by-state guide.
