Is there a way a document can be edited after being signed.
Here is my scenario:
I have a document that is being filled and signed by user A. Then at a later point user B opens the file and needs to apply changes thus invalidating the signature of user A. After changes are made user B would need to sign the document and lock it for editing.
I need to be able to either have the document set to as soon as any changes are made to it the signature field to automatically clear OR some way of locking the document to where you would need to have a password to be able to unlock the document for editing.
I'm stuck. Any advice is welcome!
Side note- there are several users that would be opening and editing the documents then re-signing them. Some are on laptops and some are on tablets.
