How to Create a Fillable PDF Form for Multiple Signatures
Question details
The user needs to create a PDF contract template that allows multiple recipients to fill out specific sections and sign sequentially, locking previously entered data without restricting upcoming fields.

- Product
- Device & OS
- not provided
- Scenario
- Creating a multi-step contract or approval form where each signer adds their respective information and locks their fields to prevent subsequent modifications.
- Observed behavior
- Configuring signature fields so they automatically lock designated form fields upon signing, while leaving other fields open for subsequent signers.
Ensure you have all the necessary form fields mapped out beforehand, clearly identifying exactly which fields need to be locked by the first signer and which should remain editable for the next recipient.
Configure Signature Properties to Lock Specific Fields
Use the signature field properties in your PDF editor to specify exactly which text boxes and options become read-only after a specific user applies their digital signature.
To achieve a sequential signing workflow where earlier entries cannot be altered by later recipients, you must link specific form fields to specific digital signature fields. When the signature is applied, the linked fields are permanently locked.
Add all the required text boxes, checkboxes, and multiple signature fields to your PDF document for all intended recipients.
Right-click the first signer's signature field and select 'Properties' from the context menu.
In the Properties dialog box, click on the 'Signed' tab to access post-signing actions.
Check the option that indicates actions to take after signing, choose 'Just these fields' (or similar wording), and select only the specific fields that the first signer is responsible for.
Repeat this process for the second signature field, instructing it to lock its corresponding fields, or 'All fields' if it is the final signature.

Frequently Asked Questions
Can I lock the entire PDF after the final person signs it?
Yes. When configuring the properties for the final signature field, you can select the option to lock 'All fields' upon signing. This prevents any further edits to the document.
What happens if someone tries to edit a locked field?
Once a field is locked by a digital signature, it becomes read-only. Any unauthorized attempt to force an edit or modify the underlying PDF structure will invalidate the digital signature, indicating the document has been tampered with.
Can recipients fill out and sign the PDF on mobile devices?
Yes, provided the recipients use a capable mobile PDF reader that supports standard PDF signature features and form field locking. However, configuring the signature rules and creating the form is best done on a desktop environment.
