I'm new at this, so I hope my post makes some sense. My ex wants to take me back to court and to get more retirement benefits from me. Is it usual or unusual for judges to reopen divorce cases? The ex now wants a survivor annuity from my Federal Government retirement benefits. We attended financial mediation, and his attorney never discussed a survivor annuity. We signed the MSA, not awarding a survivor annuity, and were divorced about 9 months ago. It seems to me that what's final should be final?????????? Thanks so much!
