Who might need a declaration of nullity of their marriage?

Any person, (i.e., Christian or non-Christian, Catholic or Protestant), who wishes to enter marriage in the Catholic Church, and who has a former spouse who is living, needs to look at the possibility of a declaration of nullity in order to determine that they are free to marry in the Catholic Church. The fact that a couple was married before a Catholic priest and two witnesses does not necessarily guarantee that all the requirements were present to establish a full and valid marriage. As part of its fundamental teaching on marriage, the Catholic Church does not recognize divorce as ending the bond established in marriage, believing that marriage is binding until death. While the presumption always exists that a marriage is valid, either of the spouses has the right to ask the Church to examine this presumption after common life has ceased, there is no hope of reconciliation, and a civil divorce has been obtained.
