Scenario
Determining legal compliance for signing official public documents electronically or digitally within California.
Observed behavior
Uncertainty regarding whether Adobe Sign's document certification meets California Government Code requirements for individual digital signatures and certificate authorities.
Before you start

Before proceeding, confirm with your legal or compliance team whether your specific document mandates a strict certificate-based digital signature or if a standard electronic signature is legally acceptable.

Solution 1Recommended

Utilize Standard Electronic Signatures Under AB 2296

For many California government workflows, standard electronic signatures are legally sufficient and do not require a state-approved digital certificate.

Under California Government Code Section 16.5 and AB 2296, public entities have the right to use and accept standard electronic signatures.

Digital signatures are a stricter, certificate-based subset of electronic signatures. By confirming that your agency allows standard electronic signatures, you can bypass the need for a specialized certificate authority.

1
Consult legal counsel

Review your agency's specific policies alongside AB 2296 to confirm if an electronic signature is acceptable for your document type.

2
Use e-signature features

If acceptable, utilize standard electronic signature tools (such as drawing or typing your name in your PDF software) to sign the document without requiring a state-approved certificate authority.

Frequently Asked Questions

What is the difference between an electronic signature and a digital signature in California?

An electronic signature is a broad term for any electronic symbol or process attached to a record (like a drawn signature). A digital signature is a more secure subset that uses cryptographic certificates from an approved Certificate Authority to verify identity and document integrity.

Does Adobe Sign act as an individual's digital signature?

No. Adobe Sign typically certifies the document as a whole to prevent tampering. However, this document certification is distinct from an individual signer applying their personal, certificate-based digital signature.

Where can I find California's approved list of certification authorities?

The approved list of Digital Signature Certification Authorities is maintained and published by the California Secretary of State on their official government website.

Do all public entities in California strictly require digital signatures?

Not necessarily. Under California Government Code Section 16.5 and AB 2296, many public entities and government agencies are permitted to use and accept standard electronic signatures for typical transactions.
