When you add a digital signature form field, you can specify an action to be executed when the form field is signed. See Signing a PDF document.

To change digital signature field properties:

  1. In the Digital Signature Properties dialog box, click the Sign tab, specify one of the following options:
    • Select Do nothing when signed. It’s the default option.
    • Select Marked “All fields” as read-only to lock all fields when the form is signed.
    • Select Marked “All fields except followings” as read-only to lock all fields when the form is signed, except the fields you selected. Click Pick. In the Field Selection dialog box, select one or more fields, then click OK.
    • Select Marked “Just these fields” as read-only to lock the fields you selected when the form is signed. Click Pick. In the Field Selection dialog box, select one or more fields, then click OK.
    • Select Execute following Scripts when signed to execute the JavaScript in the dialog box. Click Edit to edit an existing JavaScript or to create a new JavaScript action, then click OK.
  3. Click Close to apply the property options you’ve selected.
