Don't pay a fee for someone to locate your unclaimed property. Tracers are professionals who make a living finding the owners of unclaimed property. They then contact the owners, and offer to help them locate their unclaimed property for a fee. All you get for the fee is the name and address of the state unclaimed property office that has your property. If a tracer tells you there's money waiting for you, you can call the state yourself and get the money without having to pay anybody anything.
States return abandoned property for free.
If the tracer is unwilling to tell you which state has the unclaimed property, try calling or writing each of the states listed below. Start first with the states in which you've lived, and the states in which your deceased relatives lived. Also try the state in which the tracer is located, since many tracers specialize in tracing their home state's unclaimed property listings. Once you know that there is unclaimed property waiting for you in some state's coffers, it is very easy to file a claim. If all else fails, sending a postcard to each of the state unclaimed property offices will cost you less than most finder fees.
