She got married
    without a walee and her husband refuses to repeat the marriage contract
Question

                I was married about two months after becoming Muslim and at the time I did 
  not know much about riage according to the Qur'an and Sunnah. So my husband 
  (who is muslim) and I were married at a courthouse.
 I have since found out that I need a wali for my marriage to be valid, and 
  that I should be married in the correct Islamic way.
 I have spoken to my husband about this and he does not want to do this. Is 
  our marriage still valid? And if not, should I separate from him since he refuses 
  this?
Praise be to Allah.You must convince him to repeat the marriage contract with 
  the proposal from the walee (guardian) and acceptance by the husband. Try to 
  avoid him and keep away from him until the contract is redone, and Allaah is 
  with those who are patient. See also Questions #s 2127
