28 U.S.C. § 2042 : US Code - Section 2042: Withdrawal

      No money deposited under section 2041 of this title shall be
    withdrawn except by order of court.
      In every case in which the right to withdraw money deposited in
    court under section 2041 has been adjudicated or is not in dispute
    and such money has remained so deposited for at least five years
    unclaimed by the person entitled thereto, such court shall cause
    such money to be deposited in the Treasury in the name and to the
    credit of the United States. Any claimant entitled to any such
    money may, on petition to the court and upon notice to the United
    States attorney and full proof of the right thereto, obtain an
    order directing payment to him.
