The qaadi (judge) granted his wife an annulment of the marriage by khula‘ in his absence without his knowledge
Question

                My wife separated from me by khula‘ without my knowledge, and she sent me a message to that effect to the wrong address, and she did not tell me anything until after the court had granted her khula‘.  What is my legal position and what is hers? What should I do?
Praise be to Allah.
      Firstly: 

    Khula‘ is granted in return for financial compensation, such as if the wife 
    returns the mahr to the husband, or she gives up the deferred portion of the 
    mahr. The basic principle is that khula‘ should be granted by the husband, 
    but the judge may force the husband to issue a talaaq (divorce) or khula‘, 
    if he finds evidence that calls for that, such as if the wife is being 
    harmed, in which case khula‘ or talaaq may be granted through the court, in 
    which case the husband has no recourse but to refer to the court and try to 
    convince the judge to change his mind, or he can ask for an official fatwa 
    to be issued by the appropriate body in his country to declare the khula‘ 
    null and void, which he may then present to the court. 

    Secondly: 
It 
    is permissible for the judge, in the event that it is proven that the wife 
    is being harmed and the husband is absent, to separate them formally. Please 
    see the answer to question no. 12179. 

    Thirdly: 

    What you have mentioned about the notice from the court being delivered to 
    the wrong address is regarded as deceit and trickery on the part of the 
    wife, so you should appeal the ruling at the earliest opportunity. 

    And Allah knows best.
