Religious conversion under Muslim law affects inheritance, marriage, maintenance, and guardianship. Apostasy dissolves a husband’s marriage, while a wife must seek divorce. Converts gain inheritance rights under Muslim law but lose them from non-Muslim relatives, balancing faith and legal status.

Under Muslim law, guardianship (Wilayat) includes managing a minor's personal and property interests. Types include natural, testamentary, court-appointed, and de-facto guardians, prioritizing the child's welfare.
