Notes of Advisory Committee on Rules—1983
Pursuant to §506(a) of the Code, secured claims are to be valued and allowed as secured to the extent of the value of the collateral and unsecured, to the extent it is enforceable, for the excess over such value. The valuation of secured claims may become important in different contexts e.g., to determine the issue of adequate protection under §361, impairment under §1124, or treatment of the claim in a plan pursuant to §1129(b) of the Code. This rule permits the issue to be raised on motion by a party in interest. The secured creditor is entitled to notice of the hearing on the motion and the court may direct that others in the case also receive such notice.

An adversary proceeding is commenced when the validity, priority, or extent of a lien is at issue as prescribed by Rule 7001. That proceeding is relevant to the basis of the lien itself while valuation under Rule 3012 would be for the purposes indicated above.
