I'm sure some of you have used this. Each state has their own site for it. It's free and seems pretty easy to claim. I just found around $40 for me, that was a refund for my dad. I clicked on it and Indiana will mail me a claim form, or you can print one out. I'll sign it and include a death certificate and I guess I should get the money. I also found over $3,000 for a cousin of mine, who received dividends and child support after her mom died, that's in the unclaimed fund, so she's claiming that. Anyway check it out, and see if you have any money the state is holding for you.
