Michigan Unclaimed Money or Forgotten Assets
The Michigan Department of Treasury maintains a web site called Money Quest. According to their description on the page,
"The Michigan Department of Treasury has millions of dollars in lost or forgotten assets from dormant bank accounts, uncashed checks, valuables left in safe deposit boxes and stock certificates. Becuase these properties were considered abandoned and unclaimed by the bank or company entrusted with them, they are turned over to the state, as required by law."
