43 C.F.R. § 1864.0-2 – Objectives.

(a) The objective of the disclaimer is to eliminate the necessity for court action or private legislation in those instances where the United States asserts no ownership or record interest, based upon a determination by the Secretary of the Interior that there is a cloud on the title to the lands, attributable to the United States, and that:
1. (1) A record interest of the United States in lands has terminated by operation of law or is otherwise invalid; or
2. (2) The lands lying between the meander line shown on a plat of survey approved by the Bureau of Land Management or its predecessors and the actual shoreline of a body of water are not lands of the United States; or
3. (3) Accreted, relicted, or avulsed lands are not lands of the United States.
(b) A disclaimer has the same effect as a quitclaim deed in that it operates to estop the United States from asserting a claim to an interest in or the ownership of lands that are being disclaimed. However, a disclaimer does not grant, convey, transfer, remise, quitclaim, release or renounce any title or interest in lands, nor does it operate to release or discharge any tax, judgement or other lien, or any other mortgage, deed or trust or other security interest in lands that are held by or for the benefit of the United States or any instrumentality of the United States.
(c) The regulations in this subpart do not apply to any disclaimer, release, quitclaim or other similar instrument or declaration, that may be issued pursuant to any provision of law other than section 315 of the Federal Land Policy and Management Act of 1976 (43 U.S.C. 1745).
