Hi John, Signatura encrypts all documents in such a way that, unless you select it to be public, not even the platform can see its contents.

You could define the endorsement and expiration date in the document itself, which would be signed by all needed parties.

But please contact us at help@signatura.co so we can better understand your use case and help you with it. Thanks!
