Audit Trails

Each signature on a contract is imposed and affixed to the document. When you request a signature, HelloSign affixes an audit trail page to the document itself. The audit trail contains a globally unique identifier, or GUID, that can be used to look up a record in our database that shows who signed a document and when. These records include a hash of the PDF document which we can compare to the hash of a questionable PDF document to determine whether or not it has been modified or tampered with. Our statement of legality can be found here.

The non-editable audit trail ensures that every action on your documents is thoroughly tracked and time-stamped, to provide defensible proof of access, review, and signature.

Here are a list of all audit-tracked events in HelloSign:
