The discharge of lien refers to the formal process by which a lien, or legal claim, on a property or asset, is removed or released. A lien is a legal right or interest that a creditor has in a debtor’s property, usually as security for a debt or obligation. Once the underlying debt or obligation has been fully satisfied, the creditor issues a discharge of lien, which releases the lien and restores the owner’s full rights to the property or asset.
