Observed behavior

Solution 1Recommended

Add Separate Signature Fields Manually in Acrobat

Manually insert and uniquely name multiple signature fields to allow different people to sign the same document in their specific sections.

When adding multiple signature fields to a single document, each field must have a unique identifier. If two fields share the exact same name, signing one will automatically replicate that signature in the other identically named field.

Keep in mind that simply placing multiple fields on a page does not enforce a strict signing order. If sequential signing is required, you must use a dedicated routing workflow.

1
Open the Prepare Form Tool

Launch Adobe Acrobat Pro, open your existing PDF document, navigate to the 'Tools' tab, and select 'Prepare Form'.

2
Add the First Signature Field

Click the 'Add a digital signature field' icon in the top toolbar. Click and drag on the document to draw the signature box in the staff section.

3
Name the First Field

A properties box will appear. Type a unique name for this field, such as 'Staff Signature', and press Enter.

4
Add the Second Signature Field

Click the digital signature icon again, draw a second box in the supervisor section, and name it distinctly, such as 'Supervisor Signature'.

5
Save and Distribute

Save the PDF file. You can now send it to the staff member for the initial signature.

Frequently Asked Questions

Why does the second signature invalidate the first one on my PDF?

This typically happens if the document is locked after the first signature is applied. Ensure that the first signer does not check the 'Lock document after signing' option when placing their digital signature.

Do PDF signature fields need to have different names?

Yes. If two signature fields have the exact same name, signing one will automatically duplicate the signature into the other field. Always assign distinct names like 'Signature 1' and 'Signature 2' in the field properties.

Can I set up a PDF so it can only be signed in a specific order?

Standard PDF form fields alone cannot enforce a strict signing sequence. To control the order in which individuals sign, you must use an e-signature routing service like Acrobat Sign or another dedicated document workflow platform.

How do I clear a signature if I signed in the wrong field?

Right-click the signature field you want to remove and select 'Clear Signature'. Note that you can only clear your own digital signature, and this action is only possible if the document has not been locked by a subsequent signer.
