A marriage of a Sunni male with a Muslim female of any sect is

Under Muslim personal law a difference of school or sect is not an impediment to marriage, so a marriage between a Sunni male and a Muslim female of any sect is "Valid". The marriage does not change the wife's sect, and the ordinary conditions of a valid nikah must still be met; it is not void, invalid or voidable on the ground of sect alone.

Current law: For covered marriages, Uttarakhand UCC sections 4-5 now supply common conditions and recognise ceremonies including nikah. A difference of Muslim sect is not itself a prohibited relationship, but every applicable statutory condition still matters.
