People move away, lose track of investments, or die, and the accounts or funds, after a set amount of time — frequently three to five years - are reported to the state Treasurer's Escheats, Comptroller's, or Revenue office. The state then tries to track down, the owners and return the money. If you think financial property may be held by your state, the first step is to contact the appropriate office (a state by state list follows) to find out whether your name is listed. Or, in the case of the estate of a deceased person, the listing would be under his/her name.
You will then fill out a claim form which you must return together with the required identification or proof of ownership. Requirements for proving ownership may vary according to the amount of the claim and the complications involved, but frequently states will ask for such things as copies of driver's licenses, social security numbers, and bank account numbers and passbooks.
