Legal divorce after talaaq
Q:
1. If a husband, with an intention to divorce his wife, says to his wife that "I divorce you" and after that they did not have any sort of communication or any physical relationship upto three months, will it be considered as a legal divorce or the husband is again required to divorce her ?
2. Also, please tell me whether it is necessary to give a written talaqnama to the wife and if yes, who all should sign the talaqnama and is it necessary that the wife should also sign the talaqnama?
