To write a legal memo, use the standard six-part format — heading, question presented, brief answer, statement of facts, discussion, and conclusion — and keep the tone objectively predictive throughout. A memo is not a brief. Its job is to tell a supervising attorney, colleague, or client how a court would likely rule, not to argue for a particular outcome. Every choice you make while drafting flows from that distinction.
In a memo, you lay out strengths and weaknesses with equal rigor. If the law cuts against your client, you say so and explain why. The reader is relying on your analysis to make a strategic decision, and that decision is only as good as the honesty behind it. A memo that reads like an argument for one side has failed at its core purpose. A brief, by contrast, goes to a judge and emphasizes favorable law and facts while minimizing the unfavorable. Keep that line clear and the format mostly takes care of itself.
The Six Standard Sections
Nearly every legal memo follows the same order:
- Heading — the parties, the author, the date, and the subject.
- Question Presented — the specific legal issue being analyzed.
- Brief Answer — a short, direct prediction of the outcome.
- Statement of Facts — the relevant facts, without commentary.
- Discussion — the full legal analysis.
- Conclusion — a summary of the analysis and your level of confidence in the prediction.
Some offices add a Recommendations section after the conclusion, and some combine the brief answer and conclusion when the issue is simple. The six-part structure is the default, and deviating from it without reason signals inexperience to most readers.
Writing the Heading
The heading looks simple, but it matters for filing and retrieval. It contains four elements: “To” (the recipient), “From” (the author), “Date,” and “Re” (the subject). The “Re” line does the heaviest lifting. A vague subject line like “Smith matter” forces the reader to open the memo to figure out what it covers. A precise one like “Whether Smith’s noncompete is enforceable under the 2024 amendment” tells the reader exactly what they’re getting.
If the memo addresses multiple legal questions, flag that in the “Re” line so the reader knows the scope before diving in. Some offices also include a file or matter number for document management.
Framing the Question Presented
The question presented is typically a single sentence that does three things at once: identifies the legal standard at issue, names the key facts that make the question close, and frames the whole thing as a question. The standard format begins with “Whether,” “Under,” or “Does.”
A strong example: “Whether a court will find that the employer interfered with the employee’s FMLA rights when it terminated her after five consecutive absences related to a medical condition, given that she notified her supervisor within four days of deciding to take leave.”
Notice what that question does. It names the legal issue (FMLA interference), the governing law (the Family and Medical Leave Act), and the facts that make it a close call (the timing of the notification). A question that just asks “Did the employer violate the FMLA?” gives the reader nothing to work with. The legally significant facts belong inside the question because they signal what the analysis will turn on.
If the memo addresses multiple issues, write a separate question presented for each one and number them. Keep each question to a single sentence when you can, though complex fact patterns sometimes require two.
Writing the Brief Answer
The brief answer does exactly what the name suggests. It answers the question presented directly and briefly. Start with a one-word answer when you can: “Yes,” “No,” “Probably yes,” or “Probably not.” Then follow with a few sentences explaining why, hitting only the key reasons.
A solid brief answer runs about four or five sentences. The opening word gives the prediction. The next sentence restates the conclusion as a full thesis. The remaining sentences identify the main legal reasons supporting that prediction. Think of it as a preview of the discussion compressed into a paragraph. No citations belong here; the brief answer should be readable on its own without the reader needing to verify sources.
The brief answer and the conclusion serve different roles, and this trips people up. The brief answer is a pre-analysis prediction, short and self-contained, meant to be read before the discussion. The conclusion comes after the full analysis and summarizes what the discussion established. On a straightforward single-issue question, the conclusion may add little beyond what the brief answer already said. On a multi-issue memo, the conclusion pulls together threads the brief answer could only gesture at.
Organizing the Statement of Facts
The statement of facts presents every fact that matters to the legal analysis, and only those facts. Include facts that support your client’s position, facts that undermine it, and background facts the reader needs to follow the story. Leave out facts that have no bearing on the legal question, no matter how interesting they are.
Organize the facts as a narrative rather than a chronological evidence dump. Write as though you’re telling the story of what happened, grouping related facts by topic when that helps the reader see the full picture. Marching through events date by date or witness by witness mirrors how evidence was gathered, not how a reader processes information. If a precise date matters to the analysis — a statute of limitations issue, say — include it. Otherwise, let the narrative flow.
Objectivity is non-negotiable here. Do not characterize facts, draw inferences, or hint at conclusions. “The employee was absent for five consecutive days” is a fact. “The employee was excessively absent” is an argument. Every fact in this section should be something both sides would agree happened, even if they disagree about what it means. Save the meaning for the discussion.
Building the Discussion Section
The discussion is the core of the memo and typically takes up more space than every other section combined. This is where you apply the law to the facts and show your reasoning. Getting the structure right is what separates a useful memo from a confusing one.
Pick a Framework and Stick With It
Most legal writers use one of two frameworks to organize each issue within the discussion: IRAC or CREAC. IRAC stands for Issue, Rule, Application, Conclusion. You state the issue, lay out the governing rule, apply the rule to your facts, and state your conclusion. CREAC follows the same logic but leads with the conclusion: Conclusion, Rule, Explanation, Application, Conclusion. The opening conclusion tells the reader where you’re headed before you walk them through the reasoning.
CREAC tends to work better in practice because busy attorneys want the bottom line upfront. They can then decide how carefully to read the supporting analysis. Either framework is acceptable. What matters is picking one and applying it consistently throughout the discussion. Switching between IRAC and CREAC within the same memo creates a disorienting reading experience.
State and Synthesize the Rule
For each issue, start by stating the legal rule that governs. Sometimes a single statute or case provides the rule cleanly. More often, you need to synthesize the rule from multiple sources, pulling the standard from one case, a key element from another, and an exception from a third. Rule synthesis is the skill that makes legal analysis genuinely useful rather than a string of case summaries.
When synthesizing, identify the common thread across your authorities. If three cases all applied the same multi-factor test but emphasized different factors, explain the test and then show how courts have weighted those factors in practice. The goal is to give the reader a working rule they can apply, not a catalog of every case you found. After stating the synthesized rule, illustrate it with the cases whose facts most closely resemble yours.
Apply the Rule to the Facts
The application section is where the memo earns its keep. Walk through each element of the rule and match it against the specific facts of your case. Use analogical reasoning: explain how your facts are similar to or different from the facts in the cases you cited when stating the rule. “Like the plaintiff in Jones, our client notified the employer within the statutory window” is the kind of direct comparison that makes an application section work.
Avoid the trap of restating the rule in the application section. If you find yourself writing “Courts consider whether the defendant acted reasonably” for the second time, you’ve slipped back into rule explanation. The application should be fact-heavy and law-light. The law was already established above.
Address Counter-Arguments
A memo that presents only the favorable analysis is incomplete and unreliable. For every issue, consider how the other side would argue and address it. This is not a weakness; it’s the whole point of an objective memo. Your supervising attorney needs to know where the case is vulnerable before deciding how to proceed.
Present counter-arguments fairly and then explain why, on balance, you believe the analysis leans one way or the other. If the counter-argument is strong enough that you can’t confidently predict the outcome, say so. A memo that honestly says “this could go either way” is more valuable than one that papers over a genuine weakness to deliver a clean prediction.
Writing the Conclusion
The conclusion summarizes the full analysis in roughly a paragraph. Unlike the brief answer, which the reader meets before the discussion, the conclusion arrives after and should reflect the depth of the analysis the reader just worked through. State your prediction for each issue or sub-issue and indicate how confident you are. “The court will almost certainly find” signals something very different from “a court could reasonably find,” and the reader needs to know which one you mean.
Keep the conclusion free of citations. It synthesizes; it does not introduce new analysis. On a single-issue memo, the conclusion may be nearly identical to the brief answer, and some attorneys will tell you to skip it. On multi-issue memos, the conclusion is where you pull the threads together.
Research, Citation, and AI Verification
The discussion is only as strong as the research behind it. Start with primary sources: statutes, regulations, and case law directly on point. Then consult secondary sources like treatises, law review articles, and legal encyclopedias to fill gaps and identify additional primary authority. Secondary sources point you toward the law; primary sources are what you cite.
Competent legal research is an ethical obligation. ABA Model Rule 1.1 requires that lawyers bring the “legal knowledge, skill, thoroughness and preparation reasonably necessary for the representation.”1American Bar Association. Rule 1.1: Competence A memo built on incomplete research can lead to bad strategic decisions, and the attorney who signed off on it bears the responsibility.
For citation format, the Bluebook (formally The Bluebook: A Uniform System of Citation) remains the dominant standard in American legal practice. Most law schools, federal courts, and law journals use it. The ALWD Guide to Legal Citation, now in its seventh edition, is a widely accepted alternative that produces nearly identical citations but is generally considered easier to navigate. Some law schools and state courts prefer the ALWD Guide, so check your office’s conventions before defaulting to one system. Whichever you use, apply it consistently.
If you use AI tools at any stage, verify everything they produce before it goes into the memo. ABA Formal Opinion 512, issued in 2024, establishes that existing ethical rules apply fully to generative AI use. AI tools can fabricate case citations entirely, and this has already led to sanctions in federal courts. Every case, statute, and factual assertion that an AI tool generates must be confirmed against primary sources. Entering client facts into an AI tool may also expose privileged information depending on how the tool processes and stores data, so check your office’s policy before pasting case details into any outside system.
Handling and Marking the Finished Memo
A legal memo prepared to provide legal advice is generally protected by attorney-client privilege, but that protection depends on how the memo is handled after it’s written. Mark privileged memos “Attorney-Client Privileged and Confidential” and limit distribution to people who need the legal analysis to make decisions. Sharing it with third parties who don’t need the information to act on the advice is the most common way privilege is lost, and courts often find that a waiver for one purpose waives privilege broadly.
Common Mistakes to Check For Before Sending
Certain errors show up repeatedly, especially in early drafts. Knowing what to watch for saves revision time.
- Advocacy creep. You start analyzing objectively and gradually begin arguing for one side, usually your client’s. Read each paragraph of the discussion and ask whether it would change if you represented the other party. If it would, you’ve crossed from analysis into advocacy.
- Burying the answer. Attorneys reading memos are busy. If the brief answer is vague or the conclusion hides inside hedging language, the reader has to dig through the discussion to find out what you actually think. State your prediction clearly, even when it’s unfavorable.
- Hiding weaknesses. If there are risks or unfavorable authority, address them openly. A memo that presents only the strongest arguments for one side is a brief masquerading as a memo, and it exposes the supervising attorney to an unpleasant surprise later.
- Rule-heavy, fact-light application. The application should be dominated by your case’s specific facts, not restatements of legal standards. If the application reads like a second rule section, it isn’t doing its job.
- Including irrelevant facts. Every fact in the statement of facts should connect to the legal analysis. If a fact doesn’t matter to any element of any issue in the discussion, cut it.
- Vague hedging. Phrases like “it seems like” or “there may be an argument” tell the reader nothing. Commit to a prediction and explain the basis for your confidence level.
Before the memo leaves your desk, verify that every case and statute you cited is current and controlling, check that your citations match the format your office uses, and read the discussion once through from the perspective of someone meeting the issue for the first time. That is usually the position your reader is in.
