Your question requires a multi-faceted answer. If the decree was signed more than 30 days ago, it's too late to appeal or ask for a revision. If the decree was the result of a mediated settlement agreement, you are stuck with it regardless of when the decree was signed.
If the decree was signed within the last 30 days, you might file a motion for new trial claiming duress in the case. This is a hard burden to establish. You'll need a lawyer to have any chance at being successful.
