From the Islamic point of view, a woman can file for a divorce for a variety of reasons, such a husband’s ill-treatment, stinginess, negligence of duties, etc… When such a petition is made, a judge will look into the case. If he rules in favor of a divorce, the woman is divorced and receives all her rights, including any outstanding portion of her mahr [dowry].
In khul', a woman does not have to give any reasons for her desire to end her marriage. She must therefore refund her husband all the mahr he paid her. In cases of khul’, Islam requires that a woman file a divorce petition with a court or person of competent authority. The judge will then summon the husband and settle the matter, outlining the rights of the two parties.
In both divorce and khul', a woman must observe the idda [waiting period] which lasts for the duration of three menstrual periods or three intervals of cleanliness between menstruations. The husband may reinstate the marriage during idda if he so wishes, but this applies to a revocable divorce that he has initiated. If it is a khul' case, he cannot reinstate the marriage. When the idda ends, the process is complete. Needless to say, all material rights of both parties should be settled within this period, unless they willingly agree on some other procedure.
