Question details

The user needs to configure a PDF document so that applying a digital signature does not lock the remaining blank fields, allowing subsequent users to fill them out and add their own signatures.

How to Allow Multiple Users to Sign and Edit PDF Form Fields
Product
PDF
Device & OS
not provided
Scenario
Setting up a PDF form for a multi-step approval workflow where several supervisors need to fill out specific fields and sign the document sequentially.
Observed behavior
Applying the first digital signature is locking the entire PDF document or selected fields, preventing subsequent supervisors from completing their required blank fields or adding their signatures.
Before you start

Ensure you have editing permissions for the PDF form and identify exactly which fields need to remain editable for subsequent signers before modifying the signature properties.

Solution 1Recommended

Adjust Digital Signature Field Properties

Configure the signature field properties to prevent the document from locking entirely after the first signature is applied.

By default, some digital signature fields may be configured to lock the document to prevent unauthorized changes after signing. Modifying the properties of the signature field allows you to keep specific fields open for the next person in the workflow.

1
Open form editing mode

Open your PDF document in your PDF editor and enter the Form Editing mode to access the interactive fields.

2
Access signature properties

Right-click on the first digital signature field that is causing the lock and select "Properties" from the context menu.

3
Modify the Signed tab settings

Navigate to the "Signed" tab in the Properties dialog box. Ensure you do not select the option that locks the entire document after signing.

4
Specify fields to lock

If certain fields must be protected after the first signature, choose the option to lock only specific fields. Select the fields you want to protect, leaving the later supervisors' fields editable.

Adjust Digital Signature Field Properties
Test the Workflow: Always test the signing sequence with a copy of the document before deploying it to your team to ensure the workflow functions as expected.

Frequently Asked Questions

Why does my PDF become read-only after I sign it?

By default, some digital signature fields are set to lock the entire document upon signing to prevent tampering. You can change this by editing the signature field properties under the 'Signed' tab before the document is distributed.

Can I lock only specific fields after signing?

Yes, in the signature field's Properties under the 'Signed' tab, you can choose to lock only specific fields. This leaves all other fields editable while protecting the data that has already been verified.

What if a PDF is already locked by a previous signature?

If the document was locked by a previous signer, you cannot edit or sign it unless the original author adjusts the signature properties in a fresh, unsigned copy of the document and restarts the workflow.

Does WPS Office support multiple digital signatures on one PDF?

Yes, WPS PDF fully supports multiple digital signatures, allowing sequential signing by different users as long as the document isn't locked by the first signer's field settings.
