Normally, any user Rep can delete signatures that are captured Offline on the records where the user is the owner. If System Admins need to delete records in CRM Online, an error message occurs: You may not delete an Attendee with a Signature.

This is a layer of protection from Veeva out-of-the-box to avoid accidental deletion of records where the signature is captured.
