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.
