How to Create a Dynamic Stamp for Numbered Legal Attachments in PDF
Question details
The user wants to speed up the process of stamping and numbering legal filing attachments by using a single reusable dynamic stamp instead of using separate stamps and text fields.

- Product
- Device & OS
- not provided
- Scenario
- Stamping and numbering legal attachments systematically during document preparation.
- Observed behavior
- Currently using a slow process with separate stamps and text fields, and needs a way to combine attachment artwork with a promptable text field for sequential or specific numbering during placement.
Ensure you have access to a desktop PDF editor that supports form fields and JavaScript execution, as you will need to add a custom script to trigger the number prompt.
Create a Dynamic Stamp Using JavaScript
Build a reusable custom stamp that automatically prompts you to enter an attachment number when placed on the document.
Dynamic stamps incorporate a text field into the standard attachment artwork. By embedding a simple JavaScript code into the stamp's PDF file, the PDF software will display a prompt asking you to enter a specific number or text exactly at the moment you click to place the stamp.
Create a blank PDF document containing the visual design, borders, and static text of your legal stamp.
Open your PDF editor's form tools and insert a text field exactly where you want the attachment number to appear.
Right-click the text field, go to Properties, and navigate to the Calculation or Custom Script tab. Enter a JavaScript command (such as event.value = app.response('Enter Attachment Number:');) to trigger a popup dialog.
Save this document and import it into your PDF program's custom stamps palette or directory.
Select your newly created dynamic stamp from the stamps menu and click on your target legal document. A prompt will appear asking for the attachment number, which will instantly populate inside the stamp.

Frequently Asked Questions
Can I edit the attachment number after the dynamic stamp is placed?
Generally, no. Once a dynamic stamp is applied and the JavaScript populates the field, it becomes a static element on the PDF. To change the number, you will need to delete the existing stamp and place a new one.
Do I need to know programming to create dynamic stamps?
Creating a dynamic stamp requires basic scripting knowledge, specifically JavaScript, to create the dialog box that prompts users to input the attachment number during placement.
Can I use dynamic stamps on mobile PDF editors?
Most mobile PDF editors do not support the JavaScript execution required for dynamic stamps to prompt for user input. It is highly recommended to apply dynamic stamps using a desktop PDF application.
