What is the name of your state? Washington State. I found unclaimed property on the Dept. of Revenue's website. It is a bank account my mom opened for me when I was a baby. I gave them proof of my identity and proof of a name change when I was a teenager as requested. Now, since I didn't have a SS# (I didn't get it until I was 18) they want proof of the account with either a deposit slip or bank statement. It's been 37+ years so needless to say I, nor my mother, have any of that. A person on another website suggested I could sue the DOR in small claims court for the release of the claim. Is that true? How would I do that without knowing the amount of the claim (it's over $100) or having proof? Do you have any other suggestions? Thank you.What is the name of your state?
