How do I know when everyone has signed the document?

There's four ways to confirm that everyone has signed the document:

You will receive a confirmation email that the document 'has been signed by all parties'
A notification will appear in-app alerting you to the fact the document 'has been completed'
The document's status will say 'complete'
The audit trail will confirm that the last signer has 'completed signing document' and the status has been 'marked as complete'
