Legal Writing Guide

Every document you are asked to produce, whether an office memorandum, a trial brief, an appellate brief, or a bottom-line email, rests on the same foundation: a sound analysis, organized so the reader can follow it without effort. This guide explains how that foundation is built, and then shows how each document puts it to work. For the citation rules these documents rely on, see the companion Bluebook guide.

Before you pick a format, it helps to understand what every legal document is trying to do. The format is the container, and the analysis is what goes inside it. Once you see that every memo, brief, and email is built from the same underlying analysis, the formats stop looking like a list of unrelated forms and start looking like variations on one idea.

01 · Foundations

The architecture of legal analysis

Legal writing communicates an analysis. It states a legal question, supplies the governing rule, explains what that rule means, applies the rule to a particular set of facts, and reaches a conclusion. An office memorandum and an appellate brief look nothing alike on the page, yet both are built from this same sequence. Learn the sequence first, and the formats become easier, because each one is just a different way of presenting it.

Two postures

Predicting and persuading

Legal documents differ mainly in their posture. In predictive, or objective, writing, you predict how a court will resolve a question and report that prediction candidly, weaknesses included. The audience is usually a supervising attorney or the file, and the office memorandum is the classic example.

In persuasive writing, you argue for the outcome your client wants and present the law and facts in the light most favorable to that outcome, while staying candid with the tribunal. The audience is a court, and the trial brief and the appellate brief are the classic examples. The analysis underneath is the same. Only the posture changes. A memo that honestly predicts a loss and a brief that argues for a win may rely on the very same authorities.

Three kinds of reasoning

How sound analysis is built

Good analysis usually blends three forms of reasoning, supported by reasonable factual inferences.

Rule-based reasoning applies the elements or factors of a rule directly to the facts. If the rule requires three things, you show whether each one is present.
Analogical reasoning compares your client's facts to the facts of decided cases, drawing analogies to favorable precedent and disanalogies to adverse precedent.
Policy-based reasoning explains why the result you urge serves the purposes the rule was designed to advance.

The organizing paradigm

CREAC

Most legal writing programs teach a single template for analyzing one issue, and the many named variants all reduce to the same idea. This guide uses CREAC, which stands for Conclusion, Rule, Explanation, Application, Conclusion. It is a form of deductive reasoning, moving from the general, which is the rule, to the specific, which is the rule applied to these facts. Used well, it makes an argument easy to follow, because the reader always knows where in the analysis you are.

The analytical block

Conclusion. State, up front, the point the section will prove. This is the topic sentence that orients the reader and previews the rest of the block.

Rule. State the governing rule, quoted or paraphrased from mandatory authority and synthesized where several cases combine into one standard.

Explanation. Show what the rule means by illustrating how courts have applied it, using the facts, holdings, and reasoning of the precedents that give the rule content.

Application. Apply the rule to your client's facts, drawing analogies and disanalogies to the cases you just explained. This is where "Here," does its work.

Conclusion. Restate the conclusion, now earned. "Therefore," closes the loop that the opening conclusion opened.

Two discipline points

First, finish the explanation before you begin the application. Resist the urge to interleave a little rule, then a little application, then a little more rule. Let the reader understand the rule completely before watching it operate on the facts. Second, use one CREAC block for each part of the rule. A rule with three elements generally calls for three blocks, ordered as the rule is ordered, or, where strategy favors it, with the most contested element placed first. This structure recurs in everything that follows. In a memo it predicts, in a brief it persuades, and in an email it compresses to a few sentences. The skeleton does not change.

The office memorandum is the centerpiece of objective writing. It answers a legal question for someone who needs a candid forecast, not an argument. Because its purpose is accuracy rather than advocacy, a memo presents the facts neutrally, addresses the strongest counterarguments, and reaches different degrees of certainty where the law warrants. Sometimes the answer is almost certain, sometimes it is probable, and sometimes a court might go either way.

02 · Predictive writing

Open versus closed

A closed memo is written from a fixed set of authorities the professor supplies. The research is done for you, so the exercise tests your analysis and organization. An open memo requires you to find the authorities yourself, so it also tests your research and your judgment in recognizing which authorities actually matter. The format is identical, and only the universe of sources differs.

The components

What goes in a memo

i
Heading. To, From, Date, and a precise Re line identifying the client, the file, and the exact question.
ii
Question Presented. A single sentence stating the legal question together with the few facts that determine the answer. The under-does-when form keeps it disciplined.
iii
Brief Answer. The predicted answer, such as "Probably yes," followed by a compressed statement of the reasoning that supports it.
iv
Statement of Facts. The legally significant facts, plus the background needed for coherence, told accurately and without slant.
v
Discussion. The analysis itself, organized by CREAC, ordinarily one major issue per heading and one element per subsection.
vi
Conclusion. A fuller summary of the predictions, the open questions, and the additional facts that would sharpen the answer.

The Question Presented and the Brief Answer do most of the orienting work. A reader who understands those two pieces should already know where the memo is going. Here is the standard form, marked up to show the structural moves.

Question Presented · under-does-when

Under Georgia law, may a minor disaffirm a car purchase [the legal question] when she misunderstood the agent's question and so stated her age incorrectly without intending to deceive [the determinative facts]?

Brief Answer · prediction first

Probably yes. A minor may disaffirm a contract unless a fraudulent misrepresentation of age induced the other party's justifiable reliance. Because the misrepresentation here was innocent rather than fraudulent, a court would likely permit disaffirmance.

The habits of a good memo writer

Predict candidly, even when the news is bad. Meet the best counterargument rather than avoiding it. Separate what the law clearly requires from what depends on facts you do not yet have, and say which facts you would still want. A memo that pretends to more certainty than the law supports is worse than useless, because it invites reliance the prediction cannot bear.

A trial-level brief is a memorandum of law supporting or opposing a motion. The analysis is the same as a memo's, but the posture turns toward advocacy. You still state the rule, explain it, and apply it, but now you state the rule in a way that is accurate and favorable, foreground the facts that satisfy the standard, and concede only what must be conceded, explaining each time why the concession does not change the result. Where a memo assesses a counterargument, a brief answers it.

03 · Persuasive writing

The components

i
Caption. The court, the parties, the docket number, and the title of the document.
ii
Introduction. A short, persuasive orientation that frames the motion and previews the theory in a few sentences.
iii
Statement of Facts. The facts that matter to the motion, each supported by a record citation, with favorable facts placed prominently and unfavorable facts handled rather than hidden.
iv
Argument. Organized under full-sentence point headings, each followed by CREAC turned toward advocacy. An umbrella rule may contain its own sub-rules, such as a procedural rule that carries a multi-factor test.
v
Conclusion. The precise relief requested, the prayer that tells the court exactly what to order.
vi
Signature and Certificate. Counsel's signature block and the certificate of service.

The persuasive heading is what most visibly separates a brief from a memo. A memo heading labels a topic, while a brief heading argues a conclusion.

Point heading · full sentence, conclusion stated

The Court should set aside the default judgment because it resulted from excusable neglect and because the defendant has a meritorious defense.

Why it works

The heading names the relief sought, the legal standard, which is excusable neglect and a meritorious defense, and the conclusion, all in a single readable sentence. A reader skimming only the headings should be able to reconstruct the argument.

Ordering the argument

Lead with your strongest ground. If one issue is dispositive, meaning that winning it ends the matter, argue it first and let the weaker grounds follow as alternatives. Persuasion is partly a matter of sequence, and the court should meet your best argument while its attention is freshest.

The appellate brief is the most formal document, and it is governed by the rules of court. In federal practice, Rule 28 of the Federal Rules of Appellate Procedure prescribes both the contents and their order. An appellate brief argues that the court below was right or wrong, on a closed record, to a panel that did not see the trial. Its skeleton is fixed by rule, which is a gift, because you can spend your energy on the argument rather than on inventing a structure. The components below appear under appropriate headings and in the order set by Federal Rule of Appellate Procedure 28(a), and state rules follow a parallel pattern.

04 · Persuasive writing

Required components, in order

1
Corporate Disclosure. A disclosure statement where Rule 26.1 requires one.
2
Table of Contents. With page references. Drafted well, the point headings here read as an outline of the entire argument.
3
Table of Authorities. Cases alphabetized, then statutes and other authorities, each with the pages where it is cited.
4
Statement of Jurisdiction. The basis for the lower court's subject-matter jurisdiction, the basis for appellate jurisdiction, and the dates establishing that the appeal is timely.
5
Statement of the Issues. The questions presented for review, framed to suggest the answer you seek.
6
Statement of the Case. The procedural history, meaning what happened in the proceedings below and how the case arrived here.
7
Statement of Facts. The record facts, each with a citation to the record or appendix. Persuasive in arrangement, scrupulous in accuracy.
8
Summary of the Argument. A genuine summary of the reasoning, not a list that merely repeats the point headings.
9
Argument. The contentions and the reasons for them, with the applicable standard of review stated for each issue.
10
Conclusion. A short statement of the precise relief sought.
11
Certificates. The certificate of compliance with the type-volume limits, and the certificate of service.

Appellant and appellee

What the responding brief can leave out

The appellee's brief need not repeat the jurisdictional statement, the statement of the issues, the statement of the case, or the standard of review where the appellee accepts the appellant's versions. An appellee who is dissatisfied with how the appellant framed any of these, however, should restate it. Reframing the issues or the facts is itself an act of advocacy, and conceding the appellant's framing concedes ground that need not be given up.

The standard of review

How much deference the court owes

The standard of review tells the court how much deference it owes the ruling below, and therefore how you should argue the issue. A pure question of law is reviewed de novo, with no deference, which is the most favorable posture for an appellant, because the panel decides the question afresh. Findings of fact are reviewed for clear error, and discretionary rulings for abuse of discretion, both of which give the ruling below considerable protection. Identify the standard early and argue within it, because an argument pitched at the wrong standard asks the court to do something it will not do.

One skeleton, two postures

An appellant's brief seeking reversal of summary judgment will march through each issue with CREAC, arguing that the law compels the opposite result. An appellee's brief defending a judgment may lead with a threshold ground, such as that the appellant waived the argument below, and reach the merits only in the alternative. The required parts are the same, and the strategy turns them to opposite ends.

Carrying a theme

One idea, all the way through

The strongest briefs advance a single theory of the case and carry it from the summary of the argument through the point headings to the conclusion. The theme is not a slogan. It is the one idea that, if the court accepts it, decides the appeal, such as that a rule reaches only physical presence in a courtroom, or that an agency must construe an exemption narrowly. Every section should reinforce that idea rather than introduce a new one.

The most frequent legal writing a lawyer does now is email. The analysis does not get shorter because the format does, it gets compressed. The formal memorandum has not disappeared, but a lot of the advice that once filled one is now delivered by email. The discipline that produces a good memo produces a good legal email: state the bottom line first, then give a compressed version of the same analysis, which is the question, the short answer, the governing rule, and the application in a few sentences, and tell the reader what you recommend and what you still need.

05 · Correspondence

The bottom-line email, in order

Lead with the answer. The first sentence should tell a busy reader what you concluded and what you want them to do.
Give the compressed analysis. A sentence or two of rule and a sentence or two of application is usually enough, and you can attach or offer the fuller treatment.
Name the open questions. Flag the facts that would change the answer and the next step you propose.

Credibility

Professional habits that protect it

Write a clear, specific subject line, and open with a salutation matched to the reader's seniority.
Use correct grammar, spelling, and punctuation. Avoid slang, abbreviations, and emoji, because an email full of shortcuts spends credibility you will want later.
Keep it short and scannable, with one idea per paragraph, and close with a clear request and a professional signature.
Proofread before sending, and write every email as though it may be forwarded, filed, or read aloud in a deposition. Remember privilege and confidentiality, because email is discoverable.

More formal correspondence

Letters rest on the same foundation. An advice letter explains the law to a client who is not a lawyer, in plain terms and without jargon. A demand letter states a position and a requested action to an adversary. Both are persuasive or predictive writing in a different envelope.

These are the conventions that run through every document. Good analysis poorly presented reads as weak analysis, so presentation is not decoration.

06 · Craft

Organize from the large scale down

Decide the order of your issues before the order of your sentences. Open a discussion with a roadmap, divide it into issues, and divide each issue into its elements, giving one CREAC block to each. Within a paragraph, make one point. A reader should be able to find any piece of the analysis by reading the headings and the first sentence of each paragraph.

Let topic sentences carry the argument

The first sentence of each paragraph should state the proposition the paragraph will prove. A reader who reads only those first sentences should come away with the whole argument in miniature. State the rule as a proposition, such as "Documents are not commercial when they do not reveal basic commercial operations," rather than as a vague gesture toward a topic.

Make the application move visible

The application is where most analysis succeeds or fails. Signal it plainly with "Here," followed by your client's facts mapped onto the rule, and "Therefore," followed by the conclusion. Compare the facts to the cases explicitly, showing that your client's situation is like the precedent in one respect and unlike it in another, rather than leaving the comparison for the reader to construct.

Cite with precision

Cite to mandatory authority first, and use the introductory signals correctly: no signal for direct support, see for support that takes an inferential step, see also for additional support, cf. for an analogous point, and but see for contrary authority.
Use Bluebook form, give a pincite for every proposition, and never invent or guess at a citation. The Bluebook guide walks through the citation rules in detail.
Quote sparingly and exactly, paraphrase by default, and respect both copyright and the court's record. A short, well-placed quotation of decisive language is worth more than a block quotation no one reads.

Prefer plain language

Choose the shorter word, write in the active voice, and abandon legalese that adds nothing. "Before" is better than "prior to," and "under" is better than "pursuant to" when "under" will do. Plain language is not casual language, it is precise language that respects the reader's time.

Proofread relentlessly

A typo in a brief costs credibility out of all proportion to its size, because it suggests carelessness in the analysis as well. Read the document aloud, read it again on paper, and check every citation against its source before filing.
