Q. 1. What are some of the ground permitted to obtain an Church Annulment to one's marriage?
A. 1. Based on a document published by the spokesperson of the Bishops of France in July 1992, the following are legitimate reasons for the recognition of the invalidity of a marriage:
- absence of internal freedom for the husband or wife,
- force or grave fear imposed from without (Canon 1103),
- lack of intention to get engaged until death,
- exclusion of fidelity or of procreation,
- severe emotional immaturity,
- major impossibility to live in marriage,
- absence of judment,
- psychological and physical incapacity to assume the essential obligation of marriage, and
- deceit or misrepresentation of the person.
Other grounds are:
- existence of a previous marriage bond, and
- certain family ties of consanguinity (both parties from the same ancestor).
For more information regarding the invalidity of a Sacramental marriage, please consult a Catholic priest.
