If there is no way of reconciliation left between husband and wife then the husband should be asked to divorce his wife. In case, he is not ready for talaq then he should be asked to do khula. Khula can take place only when the husband and wife are ready for the same, the khula from court without the consent of any of the two is not valid as per Shariah:
قال شمس الائمۃ السرخسی: فیحتمل الفسخ بالتراضی أیضاً و ذلک بالخلع واعتبر ھذہ المعاوضۃ المحتملۃ للفسخ بالبیع والشراء فی جواز فسخھما بالتراضی۔ (مبسوط: 6/171)
Yes, if the husband is absconding and he is not giving maintenance and is not ready to give talaq or appear in court, then wife will have right to file her case in Sharai Panchayat (or Darul Qaza) and the panchayat can cancel their nikah after due investigations. After getting khula a woman will sit in iddah period and afterwards she can marry where she likes.
But as far as khula or faskh-e-nikah in
Allah (Subhana Wa Ta’ala) knows Best
