Legal writing · Structure
Legal writing structure for memos and exam answers.
The structure of a legal memorandum — question presented, brief answer, facts, discussion, conclusion — is not formatting convention. Each section has a specific cognitive job in the reader's understanding of your legal argument. Understanding why each section exists makes you a better writer.
Why structure matters in legal writing
A legal reader — whether a supervising attorney, a professor, or a judge — reads under time pressure. They need to quickly understand what legal question you are analyzing, what your conclusion is, and how you got there. Legal writing structure is optimized for that reader, not for you.
The standard office memo format — Question Presented, Brief Answer, Facts, Discussion (IRAC), Conclusion — is predictable by design. A partner who opens any memo in your firm knows exactly where to find the bottom line and exactly where to find the rule application. Predictability is a feature, not a limitation.
Exam answers follow the same logic. A professor grading 80 exams needs to quickly locate your issue identification, your rule statement, and your application. Students who write in unstructured paragraphs force the grader to hunt for these elements. Students who write in clear IRAC structure make the grader's job easy — and earn points for every visible element.
Annotated memo structure — contract formation dispute
A short office memo on an objective assent question. Each numbered section explains its function.
Worked example
① QUESTION PRESENTED Whether a binding contract formed when Defendant wrote an agreement on a restaurant receipt and signed it, but later claimed he was joking and had been drinking. ② BRIEF ANSWER Yes. A contract formed. Under the objective theory of contracts, formation depends on the offeree's reasonable interpretation of the offeror's conduct — not on the offeror's undisclosed subjective intent. ③ FACTS On the evening of December 20, W.O. Lucy and W.O. Zehmer met at a restaurant. Lucy offered $50,000 for Zehmer's farm. Zehmer wrote up an agreement on a receipt and signed it along with his wife. Lucy paid no money at the time. Zehmer now claims he was joking and had been drinking heavily. ④ DISCUSSION [Issue] Whether a contract formed when one party claims joking intent but their outward conduct was consistent with a serious offer. [Rule] Contracts are governed by the objective theory of assent: a contract forms based on what a reasonable person in the offeree's position would believe from the offeror's conduct, not on the offeror's subjective intent. Lucy v. Zehmer, 196 Va. 493 (1954). [Application] Zehmer wrote and signed a formal agreement for a specific sum. A reasonable person in Lucy's position would interpret this conduct as a serious offer. Zehmer's claimed joking intent was not communicated to Lucy and cannot retroactively negate the objective manifestation of assent. The drinking defense also fails: Zehmer negotiated terms and used unambiguous written language. [Conclusion] A binding contract formed. ⑤ CONCLUSION A court applying Virginia contract law would likely hold that a binding contract formed. Zehmer's undisclosed intent does not control.
Question Presented
One sentence. Names the legal standard and the key disputed fact. Never just 'Did a contract form?' — that tells the reader nothing about the legal issue. The QP should identify the doctrine and the facts that make it a close question.
Brief Answer
2-4 sentences maximum. Gives the conclusion AND the one-sentence reasoning. A partner who reads only the Brief Answer should understand your position and the core legal reason for it.
Facts
Only legally relevant facts — those the analysis will turn on. No narrative filler. Order matters: chronological is usually right, but start with the parties and transaction, not with what someone ate for breakfast.
Discussion (IRAC)
The heart of the memo. Issue → Rule → Application → Conclusion, in that order. The Application section is where most points are earned or lost. Show the rule working against the facts, not just restating the conclusion.
Conclusion
1-2 sentences. Restates the answer with the hedge that matters: 'A court applying Virginia law would likely hold...' Legal conclusions are probabilistic — avoid 'the court will hold' unless you are citing binding precedent on identical facts.
Common mistakes
Burying the conclusion
Legal readers are trained to expect the answer at the top (Brief Answer) and at the bottom (Conclusion). Writing a memo that only reveals the conclusion in the final paragraph forces the reader to read everything before knowing whether your analysis is going where they expected. Give the answer upfront.
Rule sections with no citation
A rule statement without a citation is an assertion, not law. Every rule in the Discussion section must be followed by a citation — case name, reporter, and year at minimum. 'A contract forms when...' needs '... Lucy v. Zehmer, 196 Va. 493 (1954).'
Application that only restates facts
The weakest application sections read: 'Here, Zehmer signed an agreement for $50,000. Therefore a contract formed.' That is a non-sequitur — you skipped the reasoning. Show the rule element meeting the fact: 'Zehmer's act of writing and signing a price-specific agreement was conduct that a reasonable person in Lucy's position would interpret as a serious offer — satisfying the objective assent standard.'
One-sentence Discussion paragraphs
Each sub-issue in your Discussion deserves a full IRAC cycle. If your discussion of the joking-intent defense is a single sentence, you have not applied the rule — you have stated a conclusion. Develop each issue fully before moving to the next.

The Legal Writing Studio lets you draft a full IRAC answer and checks your rule statements against your own notes. It won't write for you — but it will tell you which sections need more application and where your rule citations are missing.
