A legal memorandum is an internal document that gives a supervising attorney an objective prediction of how the law applies to a specific set of facts, and writing one well means following a six-part structure that lawyers have relied on for decades: Heading, Question Presented, Brief Answer, Statement of Facts, Discussion, and Conclusion. To write a legal memorandum that earns the reader’s trust, lead with your answer, show your reasoning in that order, and write to predict an outcome honestly rather than to argue for one. The format exists because attorneys skim these documents under time pressure. A memo that buries its answer or muddles its analysis wastes everyone’s time.
Why the Six-Part Structure Exists
Each section does a distinct job, and the order is deliberate. The reader first learns what question is being answered, then whether the answer is favorable, then enough factual context to follow the detailed reasoning that supports it.
- Heading — recipient, author, date, and subject.
- Question Presented — the specific legal question the memo answers.
- Brief Answer — a direct yes-or-no response with a sentence or two of reasoning.
- Statement of Facts — the factual background the analysis depends on.
- Discussion — legal rules applied to the facts in organized, step-by-step analysis.
- Conclusion — a summary of the analysis and a definitive answer.
Skipping or combining sections confuses a reader who expects information in a particular order. Keep them separate even when a section is short.
The Heading
The heading sits at the top of the first page in a standard four-line format: TO (the person who assigned the research), FROM (your name), DATE (the day you submit), and RE (the client’s name and a short description of the issue).
The RE line deserves more thought than most writers give it. “Research memo for Smith matter” forces the reader to open the document to find out what it addresses. “Smith v. Acme Corp. — Whether the non-compete clause is enforceable under the state’s new statute” tells them exactly what they’re getting. Many offices add a confidentiality designation such as “Privileged and Confidential — Attorney Work Product” below the heading to help preserve legal protections over the document.
The Question Presented
The Question Presented is the single most important sentence in the memo. It tells the reader three things at once: the legal issue, the governing area of law, and the key facts that make the question close or interesting. Think of it as a one-sentence story that ends with a question mark.
A weak Question Presented is too abstract: “Is our client liable for breach of contract?” That could describe any contract dispute on earth. A strong one folds in the facts that actually matter: “Under state contract law, did Loman’s Fashions form a binding contract to sell designer leather coats at the advertised price of $59.99, where all advertised coats sold out within fifteen minutes and the ad did not state that quantities were limited?”
Keep it as short as you can while still identifying the legal standard and the decisive facts. If you have multiple distinct legal issues, write a separate Question Presented for each one and number them.
The Brief Answer
The Brief Answer begins with a direct response — “Yes,” “No,” or “Probably not” — and then gives one to three sentences explaining the core reasoning. The reader should be able to stop here and walk into a client meeting with a defensible position.
A Brief Answer might read: “No. A court would likely find that Loman’s advertisement was an invitation to negotiate rather than a binding offer. Under the prevailing rule, an advertisement is treated as an offer only when it is definite in its terms and leaves nothing open for negotiation. Because the Loman’s circular did not limit quantities or specify that the offer was made to a particular person, a court would probably treat it as a general solicitation.”
Notice that the answer doesn’t hedge endlessly, but it also doesn’t pretend the outcome is guaranteed. It predicts, and it shows its reasoning. That’s the balance to aim for.
The Statement of Facts
Two principles control this section: include every fact the analysis relies on, and leave out everything else.
The temptation for new writers is to include only facts that help the client. That defeats the purpose. The memo exists to predict what a court would do, and a court will hear the full record. If a fact weakens the client’s position but is legally relevant, it belongs here. Omitting it doesn’t make it go away. It just makes the memo unreliable.
Organize chronologically when events unfolded over time, or thematically when the analysis involves multiple distinct legal elements. The facts should read like a story, not a legal argument. No conclusions, no loaded characterizations like “the customer unreasonably demanded.” Just what happened. Save the analysis for the Discussion.
The Discussion
This is the heart of the memo and typically its longest section. Here you prove the Brief Answer by walking through the legal rules, explaining what courts have done with similar facts, and applying those rules to your client’s situation. Organization matters as much as substance.
Pick an Analytical Framework
Most legal writing programs teach some variation of IRAC (Issue, Rule, Application, Conclusion), CRAC (which leads with the Conclusion), or CREAC (which adds an explicit Explanation step between the Rule and the Application). For longer memos, CREAC tends to be the most useful because the Explanation step is where the real analytical work happens.
In the Rule section, state the legal standard. In the Explanation, show how courts have interpreted and applied that standard in past cases: which facts mattered, what reasoning they used, what outcomes followed. In the Application, compare your client’s facts to those precedents. Without a developed Explanation, the Application becomes conclusory — you tell the reader your client wins without showing why.
Use Binding Authority Before Persuasive Authority
Not all legal sources carry equal weight. Binding authority includes the constitution, statutes, and case law from the court that would decide your case or a higher court in the same jurisdiction. If a state supreme court has ruled on the exact issue, that ruling controls — it isn’t optional for lower courts in that state. Persuasive authority includes decisions from other jurisdictions, lower courts, legal treatises, and restatements of the law. A court can consider these sources, especially when the governing jurisdiction hasn’t addressed the issue, but it isn’t required to follow them.1Legal Information Institute (LII) / Cornell Law School. Persuasive Authority
Lead with binding authority. If a statute governs, start there. Then layer in case law showing how courts have interpreted it. Bring in persuasive authority only when binding authority is thin or absent.
Address Counterarguments Honestly
Because the memo is predictive rather than persuasive, you need to address the strongest arguments on both sides. New writers often ignore the opposing side or bury it in a footnote.
A reliable approach: present the losing argument first, then the winning argument, and finish by explaining why one is stronger. If the other side has a plausible reading of the statute or a favorable case, lay it out. Then explain why your predicted outcome is more likely, usually by distinguishing the unfavorable precedent on its facts or showing that the weight of authority points the other way. This structure reassures the reader that you’ve considered the full picture.
The Conclusion
The Conclusion comes after the full analysis and serves a different purpose than the Brief Answer. Where the Brief Answer gives a quick response at the top, the Conclusion can be more nuanced.
A useful Conclusion does three things: restates your predicted outcome, identifies the key factor or factors that drive it, and flags any open questions that could change the analysis. If additional facts would strengthen or weaken the position, say so. If the law is unsettled and the outcome is genuinely uncertain, the Conclusion should reflect that rather than paper over it.
Predict, Don’t Persuade
This distinction trips up anyone who learned legal writing through moot court or advocacy exercises. A brief filed with a court is persuasive: you frame the facts favorably, emphasize authority that supports your position, and argue for a specific outcome. A memo is the opposite. Your job is to predict what a court would actually do, not to build the strongest possible case for your client.
In practice, this means disclosing both strengths and weaknesses. If the controlling case law cuts against the client, say so plainly rather than burying the problem in qualifications. If the outcome is genuinely uncertain, convey that uncertainty instead of projecting false confidence.
The tone follows from the purpose. Persuasive writing uses strong, definitive language and paints the facts in the best possible light. Predictive writing uses measured language: “A court would likely find…” or “The stronger argument is…” You’re sharing a professional judgment, not making a closing argument to a jury.
Citations in Practitioner Format
Legal memoranda use practitioner citation format rather than academic format. In the United States, that usually means the Bluebook’s Bluepages, which are designed for court documents and office memos. Practitioner citations use ordinary type and italics only, with no large-and-small caps, and tend to be more streamlined than their academic counterparts.
Give the full citation the first time you cite a source. After that, short forms keep the page uncluttered. “Id.” refers to the immediately preceding source, and “supra” refers back to a source that appeared earlier but is not the one you just cited.2Cornell University Law School. Basic Legal Citation Use short forms only when the reader can easily find the full citation by scanning nearby text. If the full citation was several pages back, repeat it.
Consistent citation serves a practical purpose beyond formality. The supervising attorney may want to pull the actual case or statute you relied on, and sloppy citation makes them hunt for it, which erodes trust in the entire memo.
Protecting the Memo as Work Product
An internal memo prepared while analyzing a client’s litigation position can qualify as work product, a category of documents that opposing parties generally cannot force you to hand over during discovery. Under federal rules, documents prepared in anticipation of litigation by or for a party are ordinarily protected from discovery. An opposing party can overcome that protection only by demonstrating substantial need for the materials and an inability to obtain equivalent information by other means. Even then, a court must protect the attorney’s mental impressions, conclusions, opinions, and legal theories from disclosure.3Cornell University Law School. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery
Mark the memo with a header such as “Privileged and Confidential — Attorney-Client Communication” or “Attorney Work Product.” The label alone doesn’t create privilege, but courts have treated it as evidence that the document was intended to be protected. Limit distribution to people who need to see it. Forwarding a privileged memo to outside parties can waive the protection entirely.
Mistakes That Undermine a Memo
Certain problems show up repeatedly in memos written by newer attorneys, and most of them stem from the same root cause: confusing a memo with a brief.
- Being conclusory in the Application. Stating that the client “clearly” satisfies a legal test without walking through each element is the fastest way to lose a reader’s confidence. The Application needs fact-to-fact comparisons with precedent, not bare conclusions.
- Omitting unfavorable facts or authority. If a controlling case goes against you, hiding it doesn’t help. The supervising attorney will eventually find it, probably at the worst possible moment. Acknowledge it, distinguish it if you can, and explain its likely impact.
- Treating the Statement of Facts as advocacy. Loaded language like “the defendant recklessly ignored” turns the Facts section into argument. State what happened and let the Discussion assign legal significance.
- Failing to connect rules to facts. Some memos spend pages laying out the legal standard, then jump to a conclusion with one or two sentences of application. The analysis should be at least as long as the rule statement.
- Writing a vague Question Presented. A question that could apply to hundreds of cases forces the reader to dig into the Discussion to figure out what the memo actually addresses. Build in the facts that make the question specific to your client.
Experienced attorneys can often tell within the first page whether a memo was written carefully or rushed. The Heading, Question Presented, and Brief Answer set the tone for everything that follows, and getting those three right goes a long way toward making the Discussion credible.
