FRCP 67: Deposit into Court
(a) Depositing Property. If any part of the relief sought is a money judgment or the disposition of a sum of money or some other deliverable thing, a party—on notice to every other party and by leave of court—may deposit with the court all or part of the money or thing, whether or not that party claims any of it. The depositing party must deliver to the clerk a copy of the order permitting deposit.
(b) Investing and Withdrawing Funds. Money paid into court under this rule must be deposited and withdrawn in accordance with 28 U.S.C. §§2041 and 2042 and any like statute. The money must be deposited in an interest-bearing account or invested in a court-approved, interest-bearing instrument.
