Users with appropriate rights can remove signatures from a document. To remove a signature, you must either have created the signature yourself, be the owner of the document, or have the Delete Entry entry access right for the document. In addition, in all cases, you must have the Delete feature right. Signatures cannot be removed if an existing countersignature depends on them.
Signatures that are old, unnecessary, or invalid and no longer needed can be deleted. Removing a signature will completely delete the signature from the document, including from the version history.
To remove a signature from a document
Open the Metadata dialog box or Metadata Pane. Select the Signatures tab.
Note: If any of the signatures that you are removing have been countersigned, removing them will also remove the signatures that countersigned them. You will be prompted to verify that you want to remove both the signatures and their countersigning signatures.
