A lien can be placed on a title for a variety of reasons. The most common being that a buyer is financing the purchase and the finance company secures its loan by placing a lien against the vehicle. In order for you to be able to place a lien, the lienor has to prove to the State that the lien can be enforceable. This proof will include documentation to support that the owner of the vehicle has agreed to place a lien on the vehicle. The document most commonly used to evidence an existing lien is a finance agreement signed by the owner of the vehicle receiving the financing and the finance company or its agent.
