EWTN Catholic Q&A
Easter Duty
Question from Lisa on 04-25-2012:

Catholics are supposed to fulfill their Easter Duty. What about Catholics who are not married in the church?

Answer by David Gregson on 12-06-2012:

Catholics who have not been married in the Church need to get their marriages convalidated ("blessed"). If either has a spouse still living, then they need to apply for an annulment. Meanwhile, fulfilling one's Easter Duty would be a sign to God that they really want to get back in His good graces. Then perhaps He will pave the way for you.
