Go to http://najaf.org/english/book/1/. From the left drop down menu select 'Divorce' and the select Khula' Divorce from the right drop down menu. This is based on Ayat. Sistani. Looks like you are right based on the following I found on Ayat. Sistani's website: 2519. A wife who is under nine and who is in her menopause will not be required to observe any waiting period. It means that, even if the husband has had sexual intercourse with her, she can remarry immediately after being divorced. 2520. If a wife who has completed nine years of her age and is not in menopause, is divorced by her husband after sexual intercourse, it is necessary for her to observe the waiting period of divorce. The waiting period of a free woman is that after her husband divorces her during her Pak period, she should wait till she sees Haidh twice and becomes Pak. Thereafter, as soon as she sees Haidh for the third time, her waiting period will be over and she can marry again. If, however, a husband divorces his wife before having sexual intercourse with her, there is no waiting period for her and she can marry another man immediately after being divorced, except if she finds traces of her husband's semen in her private part, then she should observe Iddah.
