Check an agreement.
Every agreement completed here carries a Signing Certificate with a code on it. Enter that code and this page will recompute the record from scratch and show you what it found. You do not need an account, and you do not need to have been part of the agreement.
What this page checks
Every action taken on an agreement is written down as an entry, and each entry is linked to the one before it. Change an entry afterwards and the link breaks. Repair that link and the next one breaks instead, all the way to the end.
This page rebuilds every one of those links in front of you and compares the result with what the certificate recorded at the time. It also shows a short identifier for each document, so you can confirm that the file you were sent is the file that was actually signed.
