**3. Certify Checkbox Validation - first line of text does not become red**
- When the checkbox is unselected, the first line of text should be red for both client and staff view:
- Triggers when user selects submit button and only displays if user doesn’t check certify checkbox.
- Stops Displaying as soon as the user selects checkbox.

First line of text
- Staff View: [LEGAL NAME] certifies that they have relevant knowledge of the business and are authorized to make this filing.
- Client View: [LEGAL NAME] certify that I have relevant knowledge of the business and am authorized to make this filing.
