In a situation in which a non-Catholic, previously married to a non-Catholic, subsequently marries a Catholic outside the Catholic Church, is it possible to have a Catholic marriage for the latest marriage - or recognition of that marriage - without obtaining an decree of nullity for the prior marriage?
(Answering having read the original post prior to the edit)
- The marriage of a Catholic who marries outside the Church is invalid [cf. Can. 1108 §1.]. Such a Catholic ought to contact their priest for the steps required for their reconciliation to the Church.
- Another complication to address with the priest is that the Catholic is in a relationship with a person the Catholic Church considers married.
- For a non-Catholic previously married and divorced and now wishing to marry a Catholic, they are to note from my answer linked below:
a. No marriage can occur until their prior marriage that ended in divorce is examined by the Church and a decree of nullity issued (i.e. in the eyes of the Church, that marriage never existed to begin with).
b. Once that decree has been issued, the requirements for a mixed marriage must be met for there to be a valid marriage in the Catholic Church.
Thus the Church recognizes the marriages of non-Catholics as well and considers them valid until proven otherwise.
