Not 100% sure on this, but the answer is No, since the Catholic Church recognizes the non-Catholic marriage as valid. That previous marriage would have to go through an annulment process.Roman Catholic AnswerThe above answer is correct. The question is whether your first marriage is valid. If it is valid, then you may not marry again as long as your spouse is alive. An annulment is a decree that no valid marriage ever existed. If you and your spouse are both baptized, then, in all probability your first marriage would be valid, even if it wasn't in Church as a valid marriage is contracted by two Christians who are not Catholic. If one of you has been baptized, then there would probably not be a valid marriage. In any case you still need to have it examined. I believe, however, that if you have not be baptised at all, and wish to convert and be baptized, then there is the Pauline privilege which would allow you to be married in the Church.
