Can your relgion annul a marriage when there has not been a divorce decreed???
Yes, there is absolutely no linkage between the divorce and annulment processes. Divorce is a civil matter decided upon by the civil courts. Annulment is a Church determination that the conditions necessary for a legitimate marriage were not present when the marriage took place, thereby nullifying the wedding. In all Catholic annulments, the default or starting position is that the marriage is legitimate. Unfortunately for all involved, annulment tribunals are not infallible or inerrant.
Peace be with you.
