IF there are section headings/titles that the attorney wrote in the body of the document, just assign a heading style (1-?) and then generate the TOC. The way to generate a TOC is to go to the References menu, select the Table of Contents drop-down, and select an automatic table style option.
After you've assigned the heading styles but BEFORE you generate the TOC, place the cursor where you want the TOC generated. It will place the TOC from that point forward. You may have to place page breaks before and after the TOC.
