Hi
If you are Muslim and married as per Sharia law, And have a nikahnama , you should follow the procedure of the talaque as Sharia law by issuing a talaquenama and send it as a legal notice to your wife.
Talaquenama is your option as you can't approch court for divorce ,as a Muslim man has no provision in existing divorce law whereas a Muslim wife has.
If your wife aproàches court against the talaquenama , you will be summoned and then you can ask for divorce mutually settling the issue or after issuing talaquenama if your wife refuses it you can approach a civil court with a declaration suit to legalise the talaquenama you performed as per Sharia law.
Since triple talaque is not acceptable in India by courts follow the procedure of getting the talaquenamà issued by a licensed khazi of your area.
The talaque you issue will be srutinised in court as DIVORCE on merit . Unfortunately though we criticise talaque ,a legal option for the same is not yet in paper under the existing laws for Muslim men .So legally speaking,Muslim woman's right of dissolution of marriage act, wakkaf act and Sharia law are the provisions .
