No lien valid upon request of any person other than legal owner as shown on reg cert. Whose request can a lien be valid for?

• A. The harbor master.
• B. The legal owner as shown on the registration certificate.
• C. Any person who believes there is a debt.
• D. The vessel's captain.

Answer: (B)

The key idea is that a lien on a vessel can be valid only when the request comes from the legal owner shown on the vessel’s registration certificate. The registration certificate identifies who is legally responsible for the vessel, and only that person (or their authorized agent) can trigger a valid lien. Others—such as the harbor master, the captain, or anyone who believes there’s a debt—do not have the authority to initiate a valid lien. So the lien is valid only for the owner named in the registration certificate.
