First, try to contact the bank where the account was opened. If the institution no longer exists, try to find out what happened to the institution through The Federal Reserve System's National Information Center (NIC). You can access NIC at http://www.ffiec.gov/nic.If an account has not had any activity in it for a specified period of time it is considered dormant. After an account has been dormant for seven years, it is escheated to the state. The Unclaimed Property Division of the Attorney General's Office is responsible for escheated property. You can search the Unclaimed Property Division's database at http://www.in.gov/attorneygeneral/ for property that has been escheated to it.
