Q. 1. The Catholic Church annulled my marriage without my consent. I never approved of the separation, the divorce and the annulment. Can the Church annulled my marriage without my consent?
A. 1. First of all, let us consider the meaning of an annulment:
"In the Roman Catholic Church, annulment is a canonical procedure according to the Church's Canon Law whereby an ecclesial tribunal judges whether the bond of matrimony in a particular case was entered into validly. The Church presumes that a marriage is valid until proven otherwise. Annulment is not the ecclesial equivalent of a divorce. A "Declaration of Nullity" is not a dissolution of an existing marriage, but rather a determination that a marriage was not entered into validly. An annulment has no civil consequence." [Source: http://en.wikipedia.org]
As stated above, an Annulment is a declaration that a marriage was never validly entered into. In other words, there never was a valid marriage. This declaration does not require the consent of the married party. The Church simply investigated the conditions related to the said marriage and determined if any of those conditions contradicted the teachings of the Catholic Church regarding what is necessary for a marriage to be valid.
For example, if parents forced their daughter to marry a certain man, the Catholic Church, upon investigating the matter, would conclude that such a marriage was not valid because the girl did not have a free choice in the matter. Parents cannot dictate who their children shall marry.
