An annulment is not the ecclesial equivalent of a divorce. Some accuse the Catholic Church of hypocrisy for preaching that all marriages are permanent, but still provide the means of annulment. The Catholic Church reconciles these two seemingly opposing ideas by understanding that a "Declaration of Nullity" is not a dissolution of an existing marriage, but rather a determination that a marriage never existed. While some may try to use an annulment to get around the "no divorce" rule, that is not the reason the Church has a process to declare nullity.
An annulment affirms the Scriptural basis of divorce, According to the Church, and at the same time affirms that in a true marriage a man and a woman become one flesh before the eyes of God. The Church's teach that a marriage is a Sacrament and that it is only validly contracted by the two individuals. However, various impediments can render an individual unable to contract marriage.
For this reason (or for other reasons that render the marriage null and void), after an examination of the situation by the competent ecclesiastical tribunal, the Church can declare the nullity of a marriage, i.e., that the marriage never existed. In this case, provided the natural obligations of a previous union are discharged, the contracting parties are free to marry
