Completion certificate

When an agreement reaches a completed state, Propper Sign automatically generates an Agreement Completion Audit — a PDF certificate that documents every aspect of the signing process. The certificate is designed to serve as court-admissible evidence of execution.

What the certificate contains​

Agreement details​

  • Agreement ID and subject line
  • Completion status and completion timestamp
  • Document count and page count
  • Timezone applied to all timestamps in the record

Sender information​

  • Name, email address, and organization
  • IP address at the time of sending
  • Postal address (if provided in the account profile)

Per-signer record​

Each signer in the agreement has their own section in the certificate covering:

SectionDetails
IdentityName, email address, and role
AuthenticationMethod used (email verification or access code) and verification result
LocationIP address at time of signing; optional city and region from IP geolocation
SignatureType (drawn, typed, or uploaded) and timestamp
TimelineSent, viewed, and signed timestamps
ConsentElectronic signature disclosure acceptance, with timestamp

Security and integrity section​

  • Document hashes — SHA-256 hash for each individual document
  • Package hash — Combined SHA-256 hash of the entire agreement package
  • Digital signature — A cryptographic seal applied to the completed certificate. Any modification to the PDF after signing invalidates the seal, making tampering visible in PDF readers such as Adobe Acrobat.
  • Completion timestamp — Certified time of final execution
Tamper detection

Open the certificate in Adobe Acrobat to verify the digital signature. A valid signature confirms the document has not been altered since it was generated.

Record tracking section​

  • Record type — Original (not a copy)
  • Holder — Propper Evidence Vault
  • Generated — Timestamp of certificate creation

Event timeline​

A chronological log of every significant action in the agreement lifecycle. Each entry includes:

  • Action type (sent, delivered, viewed, authenticated, signed, finalized)
  • Timestamp in UTC with timezone offset
  • IP address of the actor
  • Actor name or identifier
