Then, under “Manage Active Policies” click the notepad icon on the policy you want to edit.
On the next page, you’ll see several sections you can use to modify your client’s policy. Scroll down until you see the “Additional Insureds” section, and click on “Add or Edit” button. Follow the steps on the next page to make updates. In some cases, additional premium may apply.
