The original thought behind our service is that all parties should know under what circumstances they go into in an agreement. Therefore, the signing parties are equally important as the information that is agreed upon.
To add or remove a party to a case that is not yet completed (signed by all parties), you can recall a case back to draft mode, make the changes and resend it. The parties will be invited to sign again.
If you just want to correct an email address, you can change the email address of a party.
