California law supports the use of digital signatures in official communications with public entities—including the DMV. But not all e-signatures are created equal. To be legally binding, the signature must meet specific state requirements.
What Makes a DMV E-Signature Legal in California?
Under California Government Code Section 16.5, a digital signature holds the same legal weight as a manual one only if it meets the following standards:
✅ Unique to the person signing
🔒 Verifiable by the receiving party
🧑💻 Under sole control of the signer
📎 Linked to the document data (any change invalidates it)
📜 Conforms to Secretary of State regulations
DMV Policy on Signatures
- Accept the usual signature of the registered or legal owner with omissions or additions to the printed name. See signature examples in the Name Statement Requirement section of this chapter.
- Individual’s usual signature with omissions or additions to the printed name is on documents. Signatures can be:
- Handwritten.
- A form of script or printing by hand unique to that individual. A REG 256 (PDF) may be required stating this is the person’s usual signature.
- A stamped signature of the individual’s usual signature. A stamped signature does not have to be countersigned. Acceptance of a stamped signature applies only to DMV documents; other documents may still require an actual signature.
This ensures the integrity and security of DMV documents like titles, transfers, and dealer submissions.
Optional Use by DMV
It’s important to note: the DMV is not required to accept digital signatures—but when they do, the signature must follow these guidelines. Always confirm form-specific acceptance policies.
