E-signature security and audit trail, built for construction.

Every Notice of Commencement and lien waiver e-signed through NOC Signatures is protected by SHA-256 hashes of the original and final PDFs, signer IP and user-agent capture, an append-only audit log, and a Certificate of Completion auto-appended to every signed document. The result: an e-signature that holds up to scrutiny from a county clerk, a lender, or a court.
