JM 4-3.420
If the United States' claim has been reduced to judgment and the settlement is intended by both parties to satisfy the judgment obligation in full, a satisfaction of judgment should be filed upon full payment by the debtor under the compromise. This should be sufficient to evidence the consummation of settlement. However, if more than one obligor is bound by the judgment and the settlement is only as to one obligor's debt, only a partial satisfaction of the judgment can be executed. It is appropriate to release the judgment lien as to the settling debtor's property but not as to the property of the nonsettling debtors.
