Indiana offers a searchable database. The database shows the claim amount. The site gives specific instructions for how to file a claim. If property is not claimed within 25 years unclaimed funds become property of the state. Indiana is only one of two states with such a time restraint for claiming lost money. This site offers an interest thorough statistical breakdown of its unclaimed funds over the years. During 2010 Indiana collected $55.5 million and returned $40 million (a high return percent when compared to other states). Their analysis lists over 2.5 million properties with their geographical locations.
Currently run through the office of Greg Zoellar (Attorney General)
