Two divorced catholics want to get married in the church now can they they were not married catholic the first time?

Answer 1

If I understand your question, two divorce catholics want to marry; both of them were not married by a caholic priest the first time.

If both were catholic at the time of their frist marriage and they were not married before a priest and two witnesses, the first marriage lacks form. It would be a simple matter to have the marriage nullified due to lack of form. However, if either of the two received a dispensation from form this would not work.
