Authorization of Motor Vehicle Owner for Garage to Make Repairs and Acknowledgment of Lien is a document used to authorize a garage to perform repairs on a motor vehicle and acknowledge the garage's lien rights (the right to retain possession of the vehicle until payment has been made for the repairs). There are two types of Authorization of Motor Vehicle Owner for Garage to Make Repairs and Acknowledgment of Lien: 1. Voluntary Authorization of Motor Vehicle Owner for Garage to Make Repairs and Acknowledgment of Lien: This document is used when the owner of the motor vehicle voluntarily agrees to have repairs made by a garage and acknowledges the garage's lien rights. 2. Involuntary Authorization of Motor Vehicle Owner for Garage to Make Repairs and Acknowledgment of Lien: This document is used when the owner of the motor vehicle is unable or unwilling to pay for the repairs and the garage takes possession of the vehicle and retains it until payment has been made. This document outlines the repairs to be made, the estimated cost of the repairs, the terms of payment, and the garage's lien rights. It also includes a statement from the owner acknowledging and agreeing to the terms of the document.
