Is it permissible for a man to take back his divorced wife after she has been divorced three times, if the mufti nullified one of the divorces due to intense anger, making the divorces two, and can she be taken back with a new contract and dower, knowing that the divorced wife resides in another country?

If you consult trustworthy scholars and they inform you that some of the divorces were invalid, then there is no blame upon you for adopting their view and returning to your wife with a new contract and dowry, because your belief in the effectiveness of the three divorces was not based on following the opinion of scholars.
