If I suspect my marriage to be invalid, am I obligated to seek an annulment? Or would it be more appropriate to attempt to fix those things that made it invalid? Is that even possible; can a marriage become or be made sacramental after it has been contracted?
If you have any questions, please ask. I will do my best to answer honestly and completely.
Yes, a marriage can be convalidated and that's the preferred way. In fact, ecclesiastic courts are obligated to try and renconcile the parties if possible.
Depending on the issue, some formal measure of convalidation (e.g. privately renewing the vows by one or both parties) may or may not be necessary, so talk to an orthodox priest (one that gets the doctrine right) that has some knowledge of canon law.
But remember it takes something really drastic to cause a marriage to be null and it takes much more than suspicion to prove that nullity.
