A legal memorandum is an informal document, which is written in a brief form as a note or outline for a particular legal transaction for the purpose of assisting the parties involved, to remember particular points for future reference. It is also referred to as a ‘memo’. It may be used in court to prove a transaction or a contract was made. When writing one, the research and analysis of particular facts are applied and presented by following a structure with certain conventions. Now because each memorandum is unique, no two memoranda will be organized in the exact same way. There is room to incorporate your own style when preparing a memorandum. However, there is a general structure and components for this form of writing that can be applied to a research assignment in the ways that are most effective for the issue you have at hand.
