Thank you for your question. I am a Louisiana attorney and look forward to working with you to provide you the information you are seeking.
The previous expert was correct in that what you have at this point is a "mechanic's lien" on a movable, which is done by keeping possession of the vehicle.
You need to send him a letter telling him if payment in full is not received in 30 days you will initiate legal action to perfect your mechanic's lien and take the title to the vehicle as payment for the services rendered. If the owner of the movable has not made payment upon you giving them 30 day notice to do so, then you have to perfect that lien to acquire title. To perfect the lien and acquire title, you have to file suit in your district court in your parish to quiet title and get a court order granting you ownership which you then present to LA DMV that allows you to have the vehicle titled in your name.
This is the legal process you have to follow in LA in order to acquire the legal ownership over the movable so that you can sell it for the work done and get clear title.
