He divorced her but did not send her the divorce papers
Question

                Her husband divorced her and the ‘iddah came to an end, but she cannot get the divorce papers from the Islamic centre or get any proof of the divorce from the courts in the city to which she has moved. Is it permissible for her to remarry?
Praise be to Allah.We
      put this question to Shaykh ‘Abd-Allaah ibn Jibreen, may Allaah preserve
      him, who answered as follows:
She
      should ask for an annulment of the marriage in the city where she has
      moved to, on the grounds that her husband is absent and is not sending her
      any money to live on. This annulment will take the place of a divorce. And
      Allaah knows best.
