Font is already added to both legal styles, but if for some reason you need to use these icons on a different style then you can import the icon font into sitewide styles:
@import '/assets/fonts/legal-icons/fonts.css';
Use the <i> tag in your code:
<i class="lic" ></i>
Choose your icon below, and paste the icon name after lic in the i tag's class attribute.
For example:
<i class="lic lic-bankruptcy"></i>
