Who is required to sign registration/title documents?

The requirement for signing registration and title documents falls primarily on the registered or legal owners of the vehicle, as specified by vehicle code (VC) signature rules. This is because the purpose of these signatures is to establish ownership and legally transfer the title of the vehicle from one party to another. The law ensures that only those who hold a legal interest in the vehicle are able to make changes to its registration or title status.

This process is crucial in maintaining accurate records and preventing fraud, as the signatures serve as proof that the individuals have authorized the transfer of ownership. Without the consent of the legal owners, any attempt to transfer registration or title could lead to disputes and legal complications.

In contrast, the other choices involve roles that do not have the legal authority required to sign these documents on behalf of ownership. While a notary public can authenticate signatures, their role is not to sign on behalf of the owner. Similarly, a DMV clerk processes documents but does not have any ownership rights over the vehicle. Hence, only the registered legal owners are mandated to provide their signatures in these instances.
