- Device & OS
- not provided
- Scenario
- Distributing a PDF form for user signature and completion.
- Observed behavior
- Recipients cannot submit or sign the PDF form because certain fields are incorrectly configured as required instead of optional.
Determine how your PDF form will be distributed (e.g., via Adobe Acrobat Sign or standard file sharing), as the method for adjusting field properties depends on the specific workflow.
Configure Optional Fields in Adobe Acrobat Sign
Use this method if you are using Adobe Acrobat Sign to distribute the document to multiple signers.
When processing documents through Adobe Acrobat Sign, field requirements are tied to specific participant roles. Modifying data blocks and unchecking mandatory settings will allow participants to complete the workflow without filling out irrelevant fields.
Log in to Adobe Acrobat Sign, upload your document, and proceed to the drag-and-drop authoring environment.
Select the appropriate data blocks and signature fields, and ensure they are assigned to the correct recipient role from the participant list.
Double-click the specific form field to open its properties menu. Deselect the 'Required' checkbox so the field remains optional for the assigned recipient, then save your changes.

Set Fields to Optional in a Standard PDF Editor
Follow these steps if you are creating a fillable PDF to distribute manually or embed on a webpage without a dedicated e-signature platform.

Frequently Asked Questions
Why can't my recipients submit the PDF form?
If recipients cannot submit the form, it is likely because one or more fields are set as 'Required' but have been left blank. Modifying these fields to be optional will resolve the submission error.
Does making a signature field optional affect the legality of the document?
Making a signature field optional allows the user to submit the form without signing. If a signature is legally required for the document's validity, you must keep the signature field set as required.
Can I use JavaScript to make fields required conditionally?
Yes, advanced PDF workflows allow you to use custom JavaScript to make fields required or optional dynamically based on the user's responses to previous questions.
