The are a number of packages listed on the legal topic page for typesetting legal documents, however they are mostly for particular areas, such as German legal texts or US patent applications. Since they are too specific for a general guide, this section just looks at how to produce the paragraph numbering styles used in many legal contexts, such as terms and conditions of sale. There are two main types of paragraph numbering styles: hierarchical and non-hierarchical. The first is covered in §6.5.1 Hierarchical Paragraph Numbering and the second is covered in §6.5.2 Non-Hierarchical Paragraph Numbering.
