What is the Certificate of Signature (Audit Log)?

The DocuSeal Certificate of Signature, also referred to as the Audit Log, is a digitally generated record that accompanies every document completed through the DocuSeal platform. It provides a verifiable history of the signing process and serves as an integrity and authenticity record for legal and compliance purposes.

Generation

The Certificate of Signature is automatically generated once all participants have completed their signing actions and the document reaches a completed state. It is stored with the finalized document and remains accessible for download by the document owner or other authorized signers (if the document owner allows it).

Contents

Each certificate includes detailed metadata for every signer and signing event, including:

• Envelope ID
• Email addresses of all signers
• Timestamps for each key event (sent, viewed, signed, completed)
• IP addresses, session ID, user agents, Signers’ time zone
• Unique signature identifiers (if turned on in the admin account settings)
• Email or phone verification (based on the method the signature request was sent)

These details collectively ensure that each signing action can be independently verified, confirming the authenticity of the process and the document’s unaltered state after completion.

Legal and compliance relevance

The DocuSeal Certificate of Signature provides an auditable record that supports compliance with major electronic signature regulations, including the U.S. ESIGN Act, UETA, and the EU eIDAS Regulation.

In legal or regulatory proceedings, the certificate can be presented as evidence of:

• The identity and intent of each signer
• The sequence and timing of signing actions
• The document’s integrity and unchanged state after signing

Together with the signed document, the Certificate of Signature forms a legally admissible proof of execution under applicable electronic signature laws.
