Frequently Asked Questions

Can I delete a signature from a PDF after it has been finalized?

Generally, no. Once a document is fully signed and completed in tools like Adobe Sign, it is legally locked and cryptographically sealed to prevent tampering. You must create a new document if changes are required.

Why is there a blue line under my signature in Adobe Sign?

The blue line is often added by default below signatures to indicate where the signature is placed. It is a standard system element within the platform and usually cannot be disabled or deleted.

How do I edit a document that has already been sent for signature?

If the document is out for signature but not yet completed by all parties, you can often modify the agreement from the 'Manage' tab by cancelling the current transaction and sending a corrected version.
