There are two ways to legally end a marriage - annulment and divorce.
An annulment is a legal procedure which cancels a marriage between a man and a woman. Annulling a marriage is as though it is completely erased - legally, it declares that the marriage never technically existed and was never valid.
A divorce, or legal dissolution of a marriage, is the ending of a valid marriage between a man and a woman returning both parties to single status with the ability to remarry.
I'm aware that Islam allows divorce but what is it's stand on annulment of marriage?
