(Fatwa: 983/913/N=1434)
In case there is difference between husband and wife regarding talaq and the woman claims for talaq while the husband rejects it, then both of them should consult Darul Qaza or Shariah Panchayat for the solution of their problem. However, if the woman is sure that her husband has given her three talaqs as she heard it herself or through some reliable person then it is not lawful for her to give her husband control over her and live with him like wife.
Allah knows Best!
