12 U.S. Code § 3712 - Disposition of sale proceeds
Money realized from a foreclosure sale shall be made available for obligation and expenditure—
(1) first to cover the costs of foreclosure provided for in section 3711 of this title;
(3) then to pay any liens recorded prior to the recording of the mortgage which are required to be paid in conformity with the terms of sale in the notice of default and foreclosure sale;
(4) then to service charges and advancements for taxes, assessments, and property insurance premiums;
(6) then to the principal balance secured by the mortgage (including expenditures for the necessary protection, preservation, and repair of the security property as authorized under the mortgage agreement and interest thereon if provided for in the mortgage agreement); and
Any surplus after payment of the foregoing shall be paid to holders of liens recorded after the mortgage and then to the appropriate mortgagor. If the person to whom such surplus is to be paid cannot be located, or if the surplus available is insufficient to pay all claimants and the claimants cannot agree on the allocation of the surplus, or if any person claiming an interest in the mortgage proceeds does not agree that some or all of the sale proceeds should be paid to a claimant as provided in this section, that part of the sale proceeds in question may be deposited by the foreclosure commissioner with an appropriate official or court authorized under law to receive disputed funds in such circumstances. If such a procedure for the deposit of disputed funds is not available, and the foreclosure commissioner files a bill of interpleader or is sued as a stakeholder to determine entitlement to such funds, the foreclosure commissioner’s necessary costs in taking or defending such action shall be deductible from the disputed funds.
