Audit Trail
A behind-the-scenes log recording who did what to a document and when.
In Depth
During an electronic signing, the system quietly captures a running record: who opened the document, when they viewed it, the device or address they used, and the exact moment they signed. If anyone ever questions whether the signing was real, the audit trail is the receipt. It is a big part of why electronic signatures often hold up better than a plain paper one.
Consistent across the US, UK and EU. It is a technical and evidentiary concept rather than a defined legal term, so the meaning does not change by region, though the higher signature tiers in the EU and UK effectively demand a stronger one.
