Iam a motorcycle mechanic in Nebraska. I did work on a scooter for a cpl who now live in Nebraska. The scooter was bought and originaly titled in Florida. Hasnt been licensed in years.
Unfortunately, the use of "mechanic's lien" on this website refers to its use as a legal "term of art" in construction law and not to motor vehicles. LevelSet is a construction oriented website. You might try reposing your question on a more general legal Q&A site.
