Three divorces in one tuhr are controversial in islam .. There are three kinds of divorces in islam.
1. Talaq e Ahsan .. Its a single divorce that ends up in complete divorce on the expiry of 90 days ..
2. Talaq e Hassan .. Its a single talaq in every tuhr that becomes divorce on completion of 90 days from first pronouncement ..
3. Talaq e mubarat .. Its divorce with consent of both parties ..
Talaq e bayn is the fourth kind of divorce in which the husband verbally pronounces 3 divorces in one tuhr.. Majority of fuqha don't accept this divorce .. However it was practiced in the era of Hazrat Umar Farooq RZA and is accepted by ahnaf for the same reasons ..
In Pakistani legal system talaq process is of three months no matter how many times divorce has been pronounced ..
