Many California agencies accept electronic signatures if they meet ESIGN and state requirements; include an audit trail that shows signer identity and consent. Confirm agency e‑filing rules in advance.

What supporting documents should I attach?

Include payment evidence, correspondence, invoices, bank statements, and third‑party confirmations. Organized exhibits tied to specific statements in the narrative reduce follow‑up requests.
