This may have given rise to some questions in your mind.
You may have asked, first and foremost, why the Catholic Church would want to examine your past marriage in order to allow a future marriage to one of its members.
If you are reading this document, it is likely that you are interested in marrying a Catholic person, within the Catholic Church.
A priest or deacon, or member of the parish staff, has talked to you about your plans, and about your previous marriage which ended in divorce.
The Catholic Church recognizes, respects, and presumes this type of enduring marriage bond between persons of any faith background (and in a similar way between unbaptized persons), even if the civil government, because of divorce, no longer recognizes that a marriage exists.
