We recommend checking out the LLS Prepare to Practice LibGuide, which has some helpful resources on using Microsoft Word for legal writing and formatting:
Using Word - covers page numbering, headers, dot leaders, and other common formatting tools.
MS Word Demystified Presentation (2025) - includes the 2025 MS Word P2P Tutorial video and slides that illustrate these features.
Another resource you may find helpful is the University of Michigan’s Formatting Legal Documents in Word guide, which gives clear instructions for creating tables of contents with dot leaders and managing section breaks for different page numbering styles.
Try those resources, and if you still have questions, please reach out to the reference librarians for help.
