How then is an annulment possible?
In every presumption the opposite may be true. If sufficient evidence can be shown that a particular marriage is invalid, the original presumption no longer holds. A couple entering marriage must have the right intention and mind so that their consent to each other can genuinely produce the reality of a true marriage. They must also be capable of creating and sustaining the marriage relationship. When it can be proved that no true consent was given or that there was an inability to undertake and carry out the obligations of marriage, then the Church may declare a marriage null and void. This statement by the Church that a marriage was invalid from the beginning does not deny that a real relationship existed, nor does it imply ill-will or moral fault. Rather, it is a statement by the Church that, from the beginning, the relationship fell short of at least one o f the elements for a binding marriage.
