A memorandum of law format follows a fixed sequence of six sections: a header block, the Question Presented, a Brief Answer, the Statement of Facts, the Discussion, and the Conclusion. Each section does specific work, and the order rarely varies. What follows walks through the format section by section, with the writing conventions that experienced readers expect in each one.
Which Memo This Format Is For
Two different documents share the name “memorandum of law,” and they are written differently. A predictive memorandum (the office memo) is an internal document that forecasts how a court would likely rule. It is objective and presents both strengths and weaknesses of the client’s position. A persuasive memorandum, sometimes called a memorandum of points and authorities, is filed with a court to advocate for a specific outcome and marshals only the arguments that help the client.
The format below is the predictive office memo. The structural elements overlap with the persuasive version, but the tone, the handling of counterarguments, and the honesty about weak facts belong to the predictive form.
Standard Sections in Order
- Header or caption identifying recipient, author, date, and subject.
- Question Presented framing the specific legal issue.
- Brief Answer giving the bottom line in one or two sentences.
- Statement of Facts laying out relevant facts in chronological order.
- Discussion applying the law to the facts in a structured framework.
- Conclusion summarizing the findings without introducing new analysis.
The Header Block
Every memorandum opens with a header that sets context at a glance. Four lines, nearly universal in form:
- TO: the name and title of the person who assigned the research.
- FROM: your name.
- DATE: the date you submit the memo.
- RE: the client’s name and a short description of the legal issue.
The RE line carries more weight than most writers give it. A good one names the client, identifies the legal question concisely, and often includes a file or docket number. If someone pulls the memo off a shelf a year later, the RE line alone should tell them what it covers. “RE: Smith v. Jones — Enforceability of non-compete clause” works. “RE: Research memo” does not.
Question Presented
The Question Presented is the single most important sentence in the memo because it defines the boundaries of the entire analysis. A well-drafted question weaves together three elements: the relevant legal standard, the specific legal question, and the key facts of the client’s situation. Miss one of these pieces and the question is either too abstract to be useful or too narrow to capture the real issue.
A weak version reads: “Is our client liable for negligence?” That tells the reader almost nothing. A stronger one: “Under [jurisdiction] negligence law, which requires proof of a duty of care, breach, causation, and damages, is a restaurant owner liable for a patron’s injuries when the owner failed to repair a broken handrail on the front steps for six months after receiving written notice of the defect?” The specificity forces you to identify what actually matters before you start writing.
Each distinct legal issue gets its own Question Presented. If a memo covers two separate questions, number them and pair each with its own Brief Answer directly below.
Brief Answer
The Brief Answer sits directly below its Question Presented and delivers the conclusion up front. Start with a direct “yes,” “no,” or “probably,” then follow with one or two sentences explaining the key reason. A senior partner who reads only the header, the question, and the Brief Answer should walk away knowing the bottom line and the legal basis behind it.
Keep it tight. The Brief Answer is not the place to lay out full reasoning or hedge every possible exception. That work belongs in the Discussion. Here, commit to a position and give just enough justification to make it credible.
Statement of Facts
The Statement of Facts tells the story of the client’s situation in chronological order, without argument and without legal conclusions. Objectivity is non-negotiable. Calling a defendant’s behavior “reckless” is a legal conclusion. Describing the specific actions that someone might characterize as reckless, and letting the reader draw the inference, is proper fact-writing.
Include every fact relied on later in the Discussion. If a fact appears in the analysis but not in the Statement of Facts, there is a structural problem. The reverse also holds: avoid loading the section with irrelevant background. The test for inclusion is straightforward. Does this fact trigger or influence the application of any legal rule discussed later? If yes, it belongs. If not, cut it.
Pay particular attention to facts that hurt the client’s position. Because the office memo is predictive, omitting unfavorable facts helps no one. The supervising attorney needs the complete picture to make informed decisions, and those facts will surface eventually if the case moves forward. Writers coming from a persuasive background find this discipline the hardest part of office-memo writing, and it is also the most important.
Discussion
The Discussion is the heart of the memo. Most legal writers organize it using one of three closely related frameworks: IRAC (Issue, Rule, Application, Conclusion), CRAC (Conclusion, Rule, Application, Conclusion), or CREAC (Conclusion, Rule, Explanation, Application, Conclusion). The underlying logic is identical: identify the issue, lay out the governing law, apply it to the facts, and state the conclusion. The frameworks differ mainly in whether you lead with the issue or with the conclusion. IRAC is common in academic settings; CRAC and CREAC are often preferred in practice because they give the busy reader the answer before the analysis.
When a memo addresses multiple sub-issues, each one gets its own complete analytical cycle under a separate subheading. A negligence analysis, for instance, might require separate treatment of duty, breach, causation, and damages, with each element functioning as its own mini-IRAC that arrives at its own conclusion before the next element begins.
Writing the Rule Section
The rule section establishes the legal framework a court would use to resolve the issue. Structure it like a funnel: start with the broadest governing principle, then narrow to more specific sub-rules, definitions, and exceptions. If a statute sets the baseline rule and case law has interpreted ambiguous terms within it, present them in that order.
When prioritizing authorities, follow the standard hierarchy: constitutional provisions first, then statutes, then regulations, then case law from the highest court down. Use case illustrations to show how courts have applied the rule in practice, but keep them concise. State the holding, mention only the facts relevant to the analysis, and explain the court’s reasoning in a sentence or two. A common mistake is turning case illustrations into full case briefs with complete procedural histories. The reader needs to understand how the precedent applies to the client’s situation, not relive the prior litigation.
A related mistake is stating the rule as a single sentence and jumping straight to application. If the rule has multiple elements, define each one. If courts have split on how to interpret a particular element, acknowledge that split. The rule section should give the reader enough legal context to follow the application without needing to pull up the cases themselves.
Application and Counterarguments
The application section is where the analysis actually happens. Take each element of the legal rule and measure the client’s facts against it, drawing explicit comparisons to the precedent cases described in the rule section. If a prior case found that a six-week delay constituted unreasonable behavior, and the client’s delay was eight weeks, make that comparison directly. Vague assertions that the facts “are similar” without specifying how are the hallmark of weak legal analysis.
Because the office memo is predictive, address likely counterarguments within the application. After presenting the primary analysis, identify the strongest arguments the opposing side could raise and assess how a court would likely respond. If a counterargument is powerful enough to change the outcome, say so. The supervising attorney would rather hear bad news in an internal memo than be blindsided in court.
Conclusion
The final section is a concise summary of the findings. Restate the answer to each Question Presented, briefly note the primary reasoning, and identify any significant uncertainties or conditions that could change the outcome. Do not introduce new legal rules, new facts, or new arguments. If you find yourself breaking new analytical ground in the Conclusion, that material belongs back in the Discussion.
Some memos also include practical recommendations, such as suggested next steps or areas requiring additional investigation. Whether to include these depends on the firm’s conventions and the supervising attorney’s preferences. Either way, the Conclusion should be substantially shorter than the Discussion. If the two sections are comparable in length, the Conclusion is doing work that belonged elsewhere.
Citations Throughout
Legal citation in the United States follows one of two widely recognized systems: The Bluebook, compiled by the editors of four major law reviews, and the ALWD Guide to Legal Citation, created by the Association of Legal Writing Directors. The two systems agree on most conventions, and the choice between them depends on jurisdiction, employer, or law school. Many courts also maintain local citation rules that override both guides on specific formatting points.
Whichever system applies, every legal proposition in the Discussion needs a citation to its source. When citing case law, include pinpoint page references so the reader can locate the specific language relied on. Citing a case generally without directing the reader to the relevant passage is sloppy practice that experienced attorneys notice immediately. The same principle applies to statutes: cite the specific subsection, not just the statute number.
