Hawzah News Agency – If a Judge (Qazi) did all things for a divorce but didn’t give any certificate or any proof, can she get married again or she may have to wait for any certification or a period?
Answer: Issuing a certificate is not a prerequisite or condition for the validity of divorce. {Meaning, a certificate issued cannot be enough proof for the validity of divorce}. There should be two just male witnesses and it should be carried out by the husband himself or his representative (wakil).
