How to Fix Fillable PDF Form Uneditable After Signing
Question details
Users are unable to edit or fill out remaining fields in a shared PDF form after the first participant applies their digital signature.

- Device & OS
- not provided
- Scenario
- A fillable PDF form is shared among multiple participants who need to complete their respective sections sequentially.
- Observed behavior
- The entire PDF document becomes locked and read-only immediately after the first person adds their digital signature, blocking subsequent users from filling out the rest of the form.
Verify if the PDF requires multiple signatures or just one, and ensure you have the original, unsigned version of the form before adjusting the signature field properties.
Configure Signature Field Locking Settings
Prevent the entire document from locking by specifying exactly which fields should become read-only after a specific signature is applied.
By design, applying a certification or approval signature can lock a PDF to prevent unauthorized changes after signing. If multiple people need to sign or fill data, you must configure each signature field's properties on the original unsigned document to ensure it only locks specific fields.
Open the original, unsigned PDF form in your PDF editor and enter the Form editing mode.
Right-click the specific signature field intended for the first signer and select 'Properties' from the context menu.
In the Properties dialog box, click on the 'Signed' tab to view post-signing actions.
Check the box that says 'Mark as read-only', then select 'Just these fields' from the dropdown menu. Pick only the fields that the current signer is responsible for.
Click 'Close' to save the properties, then save the entire PDF and share it with the first signer.
Use a Dedicated E-Signature Routing Workflow
Utilize a built-in e-signature system to automatically manage who signs what and when, preventing premature document locking.

Frequently Asked Questions
Can I unlock a PDF after it has been signed and locked?
Generally, no. Once a digital signature locks a PDF to prevent tampering, you cannot unlock it without invalidating the signature. You must start over with a fresh, unsigned copy.
Why does a certification signature lock the whole form?
A certification signature is designed to prove the document has not been altered since the author finalized it. By default, it restricts all further edits to maintain strict document integrity.
How do I remove my own digital signature if I made a mistake?
If you just applied the signature and the document is not permanently locked, you can often right-click your signature and select 'Clear Signature'. However, if you saved and closed a fully locked document, you will need to use your original backup file.
