I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear about your situation.
There are only a few situations where a party to divorce can take the other ex-spouse back to court once the case is finalized.
1. He is paying you alimony and you have remarried or moved in with a new partner.
2. He is paying you alimony and your income has increased to the point where you no longer need it.
3. You have minor children, and something material has changed since the divorce that justifies changing the custody order or support (like you got a 20% raise, or he wants to change custody because there are problems with the schools in your area or something like that).
4. New evidence is discovered that could not have been known at the time of trial - usually meaning someone finds a bank account that was forgotten or hidden or some other asset not mentioned in the divorce.
5. You have violated one or more of the court orders in some way. That is the most common reason, and it most frequently comes up in disputes over how to raise the children, do custody hand-offs, vacations, and things like that.
