File a motion for contempt on the divorce issues. You can get copies of her tax information to verify her income and ask for sanctions.
As for the identity theft after divorce, call the police and report it. They will investigate and likely charge her with a crime.
don't be penny wise and pound foolish, at a minimum have an attorney look at it before you sign it. Spending some money now could save you a ton of money later when you have a good agreement that deals with the contingencies you need. It is always more expensive to fix errors later than to do it right the first time.
The felony does not get dismissed until or unless the court approves it (so it didn't happen until you plead to the misdemeanors). It is when you plea and are sentenced that the bond is no longer in effect and until then you can be charged with felony bail jumping.
