The condition for divorce is not consummation, just that the boy will
give half mahr to the wife and there is no iddah for the girl.
Divorce requires 2 just ('aadil) witnesses and the presence of father (wali) is not necessary
For the divorce to take place, it requires 2 witnesses and a shar'i talaq to be recited (court proceedings will not work).
