A mechanic’s lien is a security interest in real or personal property that is acquired by someone who adds material or labor to improve the property. A mechanic’s lien usually remains in effect until the lien holder (the auto repair shop) is paid for the material or labor added to the property. For a movable piece of property like a car, the property owner’s failure to pay the auto repair shop for material or labor may allow the auto repair shop to keep possession of the car until the owner pays for the material and labor. In the auto repair context, a mechanic’s lien is sometimes called a garageman’s lien.

In New York, a mechanic's lien, often referred to as a garageman's lien when it pertains to auto repairs, is a legal claim against a vehicle for unpaid repairs or services provided by an auto repair shop or mechanic. Under New York Lien Law, specifically Article 9, including Section 184, mechanics and repair shops can retain possession of a vehicle until they are compensated for their labor and the materials used in the repair. The lien is designed to ensure payment for the services rendered and can be enforced by selling the vehicle at a public auction if the debt is not settled within a specified time frame. It is important for the lienholder to follow the proper legal procedures, including notifying the vehicle owner of the lien and the potential sale, to enforce the lien lawfully. Vehicle owners have the right to dispute the lien and seek legal recourse if they believe the lien has been improperly placed on their vehicle.
