I live in Washington State, and have been divorced for 10 years. In the settlement, I was awarded half of a $40,000 IRA. For one reason or another, that transfer paperwork was never finalized. I have asked my ex about this $20,000, and still have not received it. If I take him to court, can I expect to receive the settlement, plus interest? Or can he claim that the original IRA has lost value, and I am now entitled to half of what it is worth now?
