Q: I want to ask about talaaq (divorce) that if husband gives divorce 3 times but he is drunk and next day he says he does not remember about the divorce, is the divorce valid?
A: Talaaq issued by an intoxicated person is valid and binding. (Raddul Muhtaar V10 P470).
In this particular case, three Talaaqs have taken place. Him remembering or not does not make a difference.
