Why does the Church not see adultery as grounds for an annulment?

[Lorenzo]

Question: My son is seeking an annulment through the Catholic Church. His ex-wife committed adultery. Why does the Church not see adultery as grounds for an annulment?

[Lorenzo]

Answer:


If your son’s marriage was valid on his wedding day, nothing that happened later in the marriageâ€"not even adulteryâ€"nullified it. That said, adultery may be evidence that your son’s wife did not enter into the marriage with the proper commitment required for a valid marriage to come into existence. If such is the case, an annulment may be possible.

On the other hand, if your son’s marriage is determined to be valid, the reality of the situation may be that he is married to a woman who is, tragically, not a good wife. Separation and civil divorce can protect him, his children, and his assets, but it cannot free him to remarry.

Remarriage in such a case will only be possible after the death of his wife or, if your son’s marriage is not sacramental (i.e., one or both spouses are not baptized), it might be possible to have the marriage dissolved.

Committing adultery once does not do the job but if committed many times with several person of the opposite sex then you may have a case - ground - for annulment: unreadiness for longtime commitment
