My ex husband filed for disability in 2015 while we were married. Now he has been approved, and we are now divorced. Am I entitled to any money from the back pay?
Your divorce decree has stipulations telling you exactly what you're entitled to. If you believe that something has changed that would entitle you to more you'll have to seek a modification of the divorce decree by returning to the family court. The court is the only place you'll get a legit answer as to whether you may be owed some money...or not.
