2. Why does the digital signatures status show up as UNKNOWN in Adobe??
3. Should I add an individual’s digital signature certificate to my trusted certificates, so its status becomes valid?
4. I have a file with a digital signature status as Valid in Adobe, but Revoked in Bluebeam/Nuance. Which is correct?
5. Why can’t documents have both digital signatures and a wet ink signatures?
6. Can I use DocuSign as my digital certificate provider?
7. Can I change the name of a document that has been digitally signed?
8. I received a document with an Expired or Revoked digital signature, what do I do?

It is recommended to digitally sign and validate all documents with the free Adobe Acrobat Reader DC or Adobe Acrobat DC to provide more consistent and accurate results.
