To prepare a legal brief, you research the record and the controlling law, draft the document in the order and format the court requires, redact anything sensitive, and file it through the court’s electronic system before the deadline runs. Each step has its own rules, and skipping any of them can get your filing bounced before a judge reads a word.
The specifics below come mostly from the Federal Rules of Appellate Procedure, which govern briefs in federal appeals courts and set the strictest requirements. Trial-level briefs (often called memoranda of law) support or oppose motions in the lower court, run shorter, and follow looser formal rules. State courts and trial courts have their own rules, so always check local requirements, but the drafting skills carry across.
Start With the Record and the Law
Research comes before writing. For an appellate brief, start with the trial court record: transcripts, exhibits, motion papers, and the judgment or order you’re challenging. Every factual claim in your brief must tie back to something in that record. If a fact isn’t in the record, the appellate court won’t consider it.
Once you understand the facts, pin down the legal questions the court has to answer. Secondary sources like treatises and encyclopedias help you orient, but you cite primary authority: the controlling federal or state statutes, regulations, and binding case law from courts above yours. The United States Code organizes the general and permanent federal laws by subject matter.1Office of the Law Revision Counsel. Detailed Guide to the United States Code Content and Features
Before you build an argument on a case, verify it’s still good law. This validation step (often called Shepardizing) flags whether later decisions have reversed, questioned, or limited the ruling. Citing a case that’s been overturned destroys your credibility with the court.
Required Sections of an Appellate Brief
Federal Rule of Appellate Procedure 28 dictates what goes into a brief and the order the sections appear in. Omit a required section or scramble the order and the clerk may reject the filing.2Cornell Law School / Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs
Tables and Jurisdictional Statement
Every brief opens with a table of contents keyed to page numbers and a table of authorities listing every case, statute, and other source cited, arranged alphabetically with the pages where each appears. Judges and clerks use these constantly to check citations and move through the argument.
The jurisdictional statement follows. It explains the legal basis for the lower court’s authority over the original matter and the appellate court’s authority to hear the appeal, with the facts that establish both.
Statement of Issues and Statement of the Case
The statement of the issues reduces the dispute to the specific questions the court must answer. Phrasing matters. A well-drafted issue statement nudges toward the result you want while staying fair to the record.
The statement of the case is a concise narrative of the relevant facts, the procedural history, and the rulings being challenged, all with record references. Keep this neutral. Save persuasion for the argument.
Summary of the Argument
Before the full argument, Rule 28 requires a summary that gives a clear and accurate overview of what follows. This is not a list of your headings. A judge should finish the summary with a working grasp of your position even if they stop reading there.
Argument
The argument is where the brief lives or dies. Most writers organize each issue with some version of IRAC: identify the Issue, state the governing Rule, Apply the rule to the facts, reach a Conclusion. CRAC and CREAC are variations on the same logic.
The application is the heavy work. Compare your facts to the cases you cite, drawing out the similarities that compel the same result or the differences that justify a departure. The judge already has the record; what they need is a clean explanation of why the law requires the outcome you want.
Address the other side’s strongest arguments head-on. Ignoring a damaging precedent or an inconvenient fact tells the judge you have no answer. Confront it, explain why it doesn’t change the result, and move on.
One requirement people routinely miss: for each issue, the argument must include a concise statement of the applicable standard of review. The standard tells the court how much deference to give the lower court. Legal questions get reviewed de novo; factual findings get overturned only for clear error. Argue under the wrong standard and you may be asking for a level of scrutiny the court won’t apply.
Break the argument with descriptive subheadings. A judge reading a 30-page brief should be able to find the section on any given point without hunting.
Conclusion
Close with a short conclusion stating the exact relief you want: reversal, remand for a new trial, modification of the judgment, or whatever outcome you’re seeking. Don’t reargue the case here.
Formatting Rules That Get Briefs Rejected
Courts enforce format strictly. Under Federal Rule of Appellate Procedure 32, the key specifications are:3Cornell Law School / Legal Information Institute. Federal Rules of Appellate Procedure Rule 32 – Form of Briefs, Appendices, and Other Papers
- Font: a proportionally spaced serif face at 14-point or larger. Century Schoolbook and Times New Roman are common choices. A monospaced font may not exceed 10½ characters per inch.
- Paper and margins: 8½-by-11-inch paper, margins of at least one inch on all sides, text double-spaced. Long quotations, headings, and footnotes may be single-spaced.
- Length: a principal brief is capped at 30 pages, or 13,000 words if you use the word-count option. A reply brief is capped at 15 pages or half the word count. Word-count briefs need a signed certificate of compliance.
- Cover colors: blue for the appellant, red for the appellee, gray for a reply brief, green for an amicus or intervenor, tan for a supplemental brief.
Citation style is a separate matter. No federal rule mandates the Bluebook, but most federal courts expect Bluebook-style citations or set their own in local rules. Check the court’s local rules; some circuits have specific preferences.
A brief that misses these specs typically comes back from the clerk for correction, which burns into your deadline. Some courts strike the filing entirely.
Deadlines and Extensions
Under the federal rules, the appellant has 40 days after the record is filed to serve and file the principal brief. The appellee then has 30 days after receiving it to file a response.4Legal Information Institute / Cornell Law School. Federal Rules of Appellate Procedure Rule 31 – Serving and Filing Briefs Some courts shorten these windows by local rule, especially those that move cases quickly to oral argument.
If you need more time, request an extension before the deadline passes. Courts grant extensions more readily when the request is early and gives a legitimate reason. Asking on the day the brief is due, with no prior warning, sends the wrong signal.
Redact Sensitive Information Before Filing
Scrub the document for personal data before it goes to the court. Federal Rule of Civil Procedure 5.2 requires redaction of:5Cornell Law School Legal Information Institute. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection For Filings Made with the Court
- Social Security and taxpayer ID numbers (last four digits only)
- Birth dates (year only)
- Minors’ names (initials only)
- Financial account numbers (last four digits only)
The duty to redact belongs to the filer, not the clerk. If sensitive data slips through, it becomes part of the public record and is harder to clean up after the fact. Other data like driver’s license numbers may warrant protection through a motion to seal or a protective order.
Ethical Obligations You’re Signing For
Every brief you sign is a representation to the court that your facts have evidentiary support, your legal arguments are grounded in existing law or a good-faith argument for changing it, and you’re not filing for an improper purpose like delay or harassment.6Legal Information Institute / Cornell Law School. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions Violations can draw sanctions: nonmonetary directives, penalties paid into court, or an order to cover the opposing party’s attorney fees caused by the misconduct. Sanctions must be proportional and limited to what’s needed to deter similar behavior. A firm is jointly responsible for violations by its attorneys or staff, absent exceptional circumstances.
You also owe the court a duty of candor. If you know of binding authority that directly contradicts your position and opposing counsel hasn’t raised it, you have to disclose it.7American Bar Association. Model Rules of Professional Conduct Rule 3.3 – Candor Toward the Tribunal You can still argue the adverse case is distinguishable or shouldn’t control. You can’t pretend it isn’t there.
Filing and Serving the Brief
Federal courts use the Case Management/Electronic Case Files (CM/ECF) system.8United States Courts. Electronic Filing (CM/ECF) When you submit through CM/ECF, the system generates a notice with the filing date and time. A document filed by 11:59 p.m. local time counts as filed that day.9Fifth Circuit Court of Appeals. ECF Filing Standards
You also have to serve every other party. For attorneys registered on CM/ECF, service happens automatically through the system. For parties not registered for electronic notice, arrange service by mail, commercial carrier, or another permitted method. The filing must include proof of service stating the date, manner, and names and addresses of those served.10Office of the Law Revision Counsel. Federal Rules of Appellate Procedure Rule 25 – Filing and Service
Electronic filings often need additional certifications: that privacy redactions have been made, that the electronic version matches any paper copy, and in some circuits that the file has been scanned for viruses.
Fees and Fee Waivers
Docketing an appeal in a federal court of appeals costs $605 under the most recent Judicial Conference fee schedule. If you can’t afford it, you can move the district court for permission to proceed in forma pauperis by filing an affidavit of your inability to pay. If granted, you can proceed without prepaying fees or posting security.11Legal Information Institute / Cornell Law School. Federal Rules of Appellate Procedure Rule 24 – Proceeding in Forma Pauperis A party already granted in forma pauperis status in the district court can usually continue on appeal without a new motion, unless the lower court certifies that the appeal isn’t taken in good faith.
New Authority After You File
If a relevant case comes down or a statute changes after your brief is filed but before the court rules, you can tell the court by letter under Rule 28(j). The letter must cite the new authority, explain its relevance by pointing to a specific page in your brief or a point from oral argument, and stay under 350 words. The opposing party may file a similarly limited response.12Office of the Law Revision Counsel. Federal Rules of Appellate Procedure Rule 28 – Briefs Courts police these letters for abuse.
