How to Write a Legal Research Memo (With a Template)

How do you write a legal research memo? You write a legal research memo by stating the question presented, giving a short answer, laying out the relevant facts, analyzing the law issue by issue under the IRAC structure (Issue, Rule, Application, Conclusion), and ending with a conclusion. A good memo is objective, cites real authority for every legal statement, and tells the reader what the law is rather than arguing one side.

A legal research memo, sometimes called an office memo or interoffice memorandum, is the internal document a lawyer uses to predict how a court would likely rule on a question. It is not a brief. A brief persuades a judge; a memo informs a colleague or client, warts and all. Below is the structure, a fill-in template, and the habits that separate a memo someone can act on from one that gets sent back.

The standard memo structure

Almost every research memo uses the same six parts, in this order.

• Heading. To, From, Date, Re. The "Re" line states the client matter and the precise legal question.
• Question Presented. One sentence that frames the legal issue together with the few facts that decide it. Keep it neutral.
• Short Answer. Two to four sentences that answer the question and name the key reason. The busy reader should be able to stop here and know where things stand.
• Statement of Facts. The facts you relied on, told plainly, including the bad ones. If a fact does not appear here, you cannot use it in the analysis.
• Discussion (Analysis). The heart of the memo, organized issue by issue using IRAC. This is where you cite cases and statutes and apply them to your facts.
• Conclusion. A short restatement of your predicted outcome and any next steps or open questions.

IRAC: the engine of the Discussion section

Each legal issue in the Discussion follows the IRAC pattern. Run it once per issue; complex memos stack several IRAC blocks under descriptive headings.

1. Issue. State the narrow sub-question. Example: "Whether a non-compete signed by a remote contractor is enforceable under California law."
2. Rule. State the controlling law with a citation. Example: California voids most non-compete agreements under California Business and Professions Code section 16600, and the California Supreme Court confirmed in Edwards v. Arthur Andersen LLP, 44 Cal.4th 937 (2008) that the statute means what it says, with narrow exceptions.
3. Application. Apply the rule to your specific facts. Compare and contrast your case with the cited authority. This is the analysis a reader cannot get from a treatise; it is your reasoning about these facts.
4. Conclusion. State the likely outcome for this issue, then move to the next.

Cite real authority for every legal statement

The single fastest way to lose a reader's trust is an unsupported legal claim. Every sentence that states what the law is needs a citation. Use the correct format so the reader can pull the source: Ashcroft v. Iqbal, 556 U.S. 662 (2009) for the federal pleading standard, or a statute like 42 U.S.C. section 1983. If reading and writing cites is shaky, see how to read a legal citation.

Before any citation goes in the memo, confirm the case is still good law. A memo that relies on an overruled decision is worse than no memo, because it gives false confidence. Walk through the check in how to shepardize a case, and use a citation check to see the treatment signal on each authority at a glance.

Keep it objective

The memo's job is prediction, not advocacy. Address the strongest counterargument honestly. If the authority is split, say so and explain which line of cases is more likely to control and why. A partner who reads only your favorable cases and then loses in court will not forget it. Objectivity is what makes a memo useful.

Write the memo faster

Most of the time in a memo goes to research, not drafting: finding the controlling cases, reading the holdings, and confirming they stand. A plain-English tool shortens that. With case law search you describe the issue and get cited authorities with plain-language holdings, and a research memo view organizes the question, the authorities, and the holdings so you can drop them into your draft. This is especially useful for solo attorneys and paralegals who do their own research. See how it works to follow the flow end to end.

Casesearch is a legal research tool, not legal advice. Always read the full opinion and verify citations before relying on them.
