LienA lien (ˈliːn or ˈliːən) is a form of security interest granted over an item of property to secure the payment of a debt or performance of some other obligation. The owner of the property, who grants the lien, is referred to as the lienee and the person who has the benefit of the lien is referred to as the lienor or lien holder. The etymological root is Anglo-French lien or loyen, meaning "bond", "restraint", from Latin ligamen, from ligare "to bind".
Mechanic's lienA mechanic's lien is a security interest in the title to property for the benefit of those who have supplied labor or materials that improve the property. The lien exists for both real property and personal property. In the realm of real property, it is called by various names, including, generically, construction lien. The term "lien" comes from a French root, with a meaning similar to link, which is itself ultimately descended from the Latin ligamen, meaning "bond" and ligare, meaning "to bind".
