What Is A Legal Memorandum?

A legal memorandum is a document that summarizes the facts of a case. The memorandum is written to support the argument of the lawyer. It’s written to convince a judge or jury of his or her argument, and it’s supposed to persuade those who read it before they make their decision about whether your client should win their case.

A good legal memo will contain:

  • A clear statement of what question you plan to answer;
  • An overview of all relevant existing law;
  • Your analysis and arguments as well as citations (to cases and statutes);
  • A conclusion that sums up your position on this issue after reviewing all relevant law, precedent, and policy considerations

The Purpose Of A Legal Memorandum

A legal memorandum is a brief written summary of an issue. It provides a concise summary of a legal problem, the relevant facts, and any applicable law. You should also include in your memo what you think the rule should be and why it should be that way. Note: This is not an introduction; it’s an answer to the question posed by the assignment or class discussion topic!

  • Identify your audience (who will read this?);
  • Write clearly with proper grammar and spelling;
  • Be organized (numbering each point makes it easier for readers to follow);
  • Use paragraphing (use periods after each paragraph);

Include citations if necessary—these are usually in parentheses or brackets following quoted material from another source; examples include [Case Name], [Section Number] ([Section Name], [Section Number]), etc.; do not use footnotes unless specifically instructed otherwise by your professor.

Subject Headings And How To Write Them

A great way to organize your memorandum is by using headings. Headings help you organize your facts, issue statement, rule or principle, and conclusion.

You should have at least five subject headings in a memorandum and they should be organized in order of importance (beginning with most important). If you are writing a legal memorandum for work or school, here are some general rules:

o The first heading should be “Background.” This is where you would put the facts about why this case was decided the way it was (if there are any).

o The second heading should be “Issue.” This is where you would write about what issue has been brought up in this case and what side of the argument each party agrees with. 

For example: “To determine whether Mr. Smith can deduct his business meals from his gross income under section 1120(a)(1), we must first address whether such expenses qualify as ordinary and necessary expenses under Code Section 162(a)(1).

o The third heading should be “Discussion” or “Conclusion” depending on which one makes more sense given what needs to happen next within the text itself. 

In other words, if it makes sense because there needs to be discussed then use “Discussion,” but if not then use “Conclusion” instead since there won’t need any further discussion after this point which means everything has been said already anyway so why waste time talking about things when they’ve already been discussed before?

Facts In A Legal Memorandum

Facts are the actual events that happened. Facts are the evidence that supports your opinion, the reason for the opinion, and often the reason for the decision or change in the law.

In a legal memorandum, facts are found by reviewing cases and statutes to determine what facts have been established by those sources of authority. For example, if you’re writing about whether someone has committed malpractice against another person (the plaintiff), you would need to research the legal precedent that addresses this question before writing about it yourself.

Issue Statement In A Legal Memorandum

The issue statement is one of the most important parts of your memorandum. It’s what you will use as a reference as you write about the facts and law. While you may need to make minor changes when writing your memorandum, it should be written in a way that can easily be referenced if there are any issues with understanding or application later on.

The issue statement should include:

  • A brief overview of what type of legal issue(s) are being addressed (for example, tort law or contract law).
  • A summary of why this case or scenario matters—what is at stake? This may include monetary damages, government policy implications, and/or broader societal implications (if any).
  • An explanation of how the court decided this particular case or scenario, including citations so that readers can see where they go for more information if necessary.

Rules/Principles/Application To Facts In A Legal Memorandum

A legal memorandum is a document that summarizes and applies the law to a particular situation. To write your memo, you must first understand what types of sections are included within it. First, there will be rules, principles, or applications to facts. 

Then some conclusions are often found at the end but may also appear in other places throughout the document depending on how your professor wants you to write it.

Rules: A rule is something that cannot be broken or defied (e.g., “No one can break the law”). It is written in black and white under Roman Numerals so they can be easily referenced if needed later on in court proceedings should they arise from this case study scenario we’ve come up with just for this purpose!

Principles: A principle applies across multiple situations (e.g., “All people should have equal access rights when accessing public facilities such as parks”). 

These can also go under Roman Numerals but their applicability extends beyond just one set of facts into many different scenarios around town (or country). 

We typically list them separately from our rules section just so everyone knows what these two terms mean before reading further down below into Section III where I explain how each section should be formatted.”

Conclusion Section Of A Legal Memorandum

The conclusion should be short. It is important to restate the rule, application of the rule, and facts as they were presented in your memorandum. You also need to make sure that you restate the issue regarding the subject heading by summarizing why you concluded that there was a violation or non-violation of some legal principle or statute.

When You Write A Legal Memorandum, Organize Your Issue, Facts, Conclusion, And Rule Section

A legal memorandum should be organized into three main sections: the issue, facts, and conclusion section. The issue, facts, and conclusion section should also include a separate rule section. 

In your conclusion paragraph, you should summarize the facts and then state how these facts support your rule of law. The rule of law is an interpretation of legislation or case law that will guide future decisions by other lawyers and judges.
