If you divorced her in three different occasions, you can’t marry her any more until she marries a man a true and real marriage and after consummating the marriage, she gets divorced. Only then, you can marry her again providing her marriage and divorce of the second man was not with the intention to get back to you.

If you divorced her three times in one sitting, this counts as one divorce but if the divorce was registered in the Islamic court, only it can dissolve it!

I wish to marry the same lady of whom I gave triple talaq under unpleasant grounds, we regret and want to marry again, eidha period is also over.
