Begin page numbering with the first white page of the brief itself. Since the Abstract does not have a page limit, and since the clerk's office will need to count your Argument pages, this numbering technique will simplify that job. Number pages at either the bottom center or bottom right. Just a simple number will do. Use either left or full justification in your briefs.
Many people like to fully justify the print because it looks very neat and precise.
For ease of reading, consider typing headings in normal type in the Table of Contents, even though you have put them in caps, bold, italics, or underlining in the body of the Argument. Duplicate the outline numbering system you've used for these headings in the body of the Argument, and do indent the sub-headings. Use dot leaders . . . . . . . . . . . . . . to connect the table entry and the page or pages where it is located. Avoid manually typing a period space period space etc. until you get to the right margin. You will end up with a wavy line at the right margin.
