To write a legal brief, follow the structure the court requires, support every claim with a citation to law or to the record, and meet the formatting and filing rules exactly as written. Federal appellate courts spell out the sections, order, type size, word limits, and cover colors in the Federal Rules of Appellate Procedure, and clerks reject briefs that miss any of them. The template below walks through each required part of an appellate brief, how to build the argument section, and the formatting and filing rules that trip people up.
Know Which Kind of Brief You’re Writing
“Brief” covers two very different documents. A trial brief is filed in the trial court, often tied to a motion like a motion to dismiss or for summary judgment. It tends to be shorter, less formally structured, and focused on a narrow question. Many trial judges skim it and then hear oral argument, so the brief supports the spoken presentation rather than replacing it.
An appellate brief is the primary vehicle for argument on appeal. Most appellate judges decide cases based on the briefs before oral argument happens, and the formatting and content requirements are strict. The template here is built around appellate briefs because that is where the rules are most unforgiving. The core principles of legal argument apply either way.
The Required Sections of an Appellate Brief
Federal Rule of Appellate Procedure 28 lists every section an appellant’s brief must contain, in order.1Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs Missing one can mean the court refuses to consider your arguments.
Front Matter
Open with a disclosure statement if the court’s rules require it, then a table of contents with page references, then a table of authorities listing every case, statute, and other source you cite, with the pages where each appears. Judges and clerks use the table of authorities to check whether you’ve addressed the key precedent. List cases alphabetically, with statutes and other authorities in separate sections.
Jurisdictional Statement
Explain why the court can hear the case. Identify the basis for the lower court’s jurisdiction, the basis for the appellate court’s jurisdiction, the filing dates showing the appeal was timely, and confirmation that you are appealing a final order or that jurisdiction exists on some other basis. Cite the statutes. If the appellate court lacks jurisdiction, nothing else matters.
Statement of the Issues
Frame the legal questions you want decided. Each one should be clear enough that a reader unfamiliar with the case understands what is at stake. How you phrase an issue matters: a well-crafted statement points toward your answer without reading as argument.
Statement of the Case
Under the current rule, this combined section covers the facts relevant to the issues on appeal, the procedural history, and the specific rulings you are challenging, all with citations to the record. Nearly every factual sentence needs a record citation pointing to a specific document and page in the trial court record.
This section is quietly one of the most persuasive parts of the brief. You must include all legally relevant facts, including unfavorable ones, but you control the framing: order, emphasis, and word choice. Referring to your client by name while calling the other side “Defendant” or “Plaintiff” creates a subtle human connection. Aim for a narrative that reads like a story and leads the judge toward your view of the case, without exaggerating or burying inconvenient facts.
Summary of the Argument
A concise overview of your main arguments, written as a self-contained narrative. Rule 28 specifically requires that this section not merely repeat the argument headings. A busy judge should be able to read this alone and understand your position.
Argument
Your legal analysis, with citations to authority and to the record. Each issue must include a statement of the applicable standard of review. More on how to build this section below.
Conclusion, Signature, and Certificate of Service
The conclusion is short and direct: state exactly what relief you want. After it, include the signature block and a certificate of service confirming the brief has been delivered to all other parties. If Rule 32 applies, add a certificate of compliance verifying the brief falls within the applicable word or page limit.
Building the Argument Section
The argument is where cases are won or lost on paper. Disorganized reasoning frustrates judges; a clean structure builds credibility before you reach the substance.
Use IRAC or CRAC for Each Issue
Most legal writers organize each argument using IRAC (Issue, Rule, Application, Conclusion) or CRAC (Conclusion, Rule, Application, Conclusion). IRAC states the legal issue first, identifies the governing rule, applies that rule to your facts, and reaches a conclusion. CRAC leads with the conclusion so the reader knows your position up front. Both force you to connect law to facts in a logical sequence instead of making abstract assertions.
For each issue, identify the governing rule, explain what it requires, and then show fact by fact how the evidence satisfies or fails each element. Specificity wins. Vague claims like “the evidence clearly shows” do nothing. Pointing to a specific piece of testimony or a specific document and tying it to a specific legal element is what moves a judge.
State the Standard of Review
Every issue on appeal is evaluated through a standard of review, which tells the appellate court how much deference to give the lower court. The three most common are:
- De novo. The appellate court reviews the legal question from scratch, with no deference to the trial court. Applies to pure questions of law.
- Clearly erroneous. The court will overturn a factual finding only if it is left with a firm conviction that a mistake was made. Applies to factual findings by a judge.
- Abuse of discretion. The court will overturn only if the lower ruling was unreasonable or arbitrary. Applies to discretionary rulings like evidentiary decisions.
Getting the standard right matters strategically. De novo review gives you the best shot at reversal because the appellate court owes no deference. Abuse of discretion requires you to show more than disagreement with the ruling.
Address the Other Side’s Best Points
Judges notice when a brief ignores obvious weaknesses. Acknowledge the strongest counterarguments and explain why they don’t change the outcome. Opposing counsel will raise them regardless, and you want the court to hear your framing first.
Cite the Record for Every Fact
Every factual assertion in the argument needs a citation to the specific location in the trial court record. Appellate courts have declined to consider factual claims without record citations. The typical format references a document number and page from the lower court’s docket, such as “Doc. 47 at 5.”
Formatting, Length, and Cover Rules
Clerks reject briefs for formatting problems before a judge ever sees them, and resubmission deadlines aren’t always generous.
Type and Spacing
Under Rule 32, briefs must use a proportionally spaced typeface of at least 14-point (including footnotes) or a monospaced typeface of at least 10.5 characters per inch.2Legal Information Institute. Federal Rules of Appellate Procedure Rule 32 – Form of Briefs, Appendices, and Other Papers Body text is double-spaced; headings, footnotes, and block quotations may be single-spaced. The Supreme Court has its own distinct requirements, including a booklet format and the Century font family at 12-point type.3Legal Information Institute. Supreme Court Rule 33 – Document Preparation: Booklet Format; 8 1/2- by 11-Inch Paper Format
Word and Page Limits
A principal brief in the federal courts of appeals cannot exceed 30 pages or, under the type-volume option, 13,000 words. A reply brief is limited to 15 pages or 6,500 words. The Supreme Court sets its own limits: 13,000 words for merits briefs by the petitioner or respondent, and 8,000 words for amicus curiae briefs. Most briefs include a certificate of compliance confirming the word count.
Cover Colors
Federal appellate courts require color-coded covers on printed briefs so judges and clerks can identify the filer at a glance:
- Blue: Appellant’s brief
- Red: Appellee’s brief
- Gray: Reply brief
- Green: Amicus curiae brief
- Tan: Supplemental brief
- White: Appendices and other papers
These color requirements do not apply to self-represented parties.
Check the Local Rules
Every federal circuit, and many state courts, add local rules on top of the general ones. Some require a special appendix when attachments exceed a certain length. Others mandate a statement of related cases. The Second Circuit requires the docket number on the cover in type at least one inch high. Not checking local rules is one of the most common reasons briefs come back. Pull them up before you start formatting.
Citing Law and the Record
Accurate citation separates a credible brief from one judges distrust on sight. Federal courts and most state courts expect citations to follow The Bluebook: A Uniform System of Citation, or in some jurisdictions the ALWD Guide to Legal Citation. Every legal proposition needs a supporting authority, and the reader should be able to locate that authority immediately from your citation. For cases, that means the case name, reporter volume, page, court, and year; for statutes, the title, section, and year.
Factual assertions need record citations for the same reason. Courts have treated unsupported factual claims as waived, so if a sentence states a fact, it should carry a pointer to where that fact lives in the record.
Filing: PDF Requirements and Redactions
Most federal courts require electronic filing through CM/ECF. The brief must be submitted as a text-searchable PDF generated directly from your word processor, not a scanned paper document.4Ninth Circuit United States Court of Appeals. Technical Guide to Working with PDF Documents Scanning creates an image-based file that can’t be searched or copied, and that violates filing requirements in many circuits. Some courts also require electronic bookmarks mirroring the table of contents so judges can navigate quickly. Check the court’s file size limits too; some cap individual documents at 60 megabytes.
Federal Rule of Civil Procedure 5.2 requires that certain sensitive information be redacted from any document filed with the court. The categories are:
- Social Security numbers: include only the last four digits
- Taxpayer identification numbers: include only the last four digits
- Birth dates: include only the year
- Names of minors: use initials only
- Financial account numbers: include only the last four digits
Courts can order redaction of additional categories like driver’s license numbers or immigration identification numbers in specific cases.5Legal Information Institute. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection For Filings Made with the Court Failing to redact exposes private information in the public record and creates problems that are hard to undo later.
What You’re Certifying When You Sign
Filing a brief is a certification. Under Federal Rule of Civil Procedure 11, every attorney or self-represented party who signs and files a document certifies that the legal arguments are supported by existing law or a good-faith argument for changing it, the factual claims have evidentiary support, and the filing is not being submitted for an improper purpose like harassment or delay.6Legal Information Institute. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers
If a court finds a violation, it can impose sanctions designed to deter the behavior, including orders to pay the opposing party’s attorney’s fees, payment of a penalty to the court, or nonmonetary directives like required legal education. Rule 11 includes a 21-day safe harbor: before filing a sanctions motion, the opposing party must serve it on you first, and you have 21 days to withdraw or correct the challenged filing. Courts can also initiate sanctions on their own. Don’t overstate the law, don’t fabricate facts, and don’t file anything you haven’t personally verified.
If You’re Representing Yourself
Courts hold self-represented filers to the same procedural standards as licensed attorneys. The same rules of appellate procedure, formatting, and deadlines apply, and courts are not required to overlook deficiencies because you lack legal training.
The most common mistakes are missing required sections, failing to support arguments with citations to legal authority, and failing to tie arguments to specific errors by the trial court. Saying the lower court “got it wrong” is not enough. Identify the specific ruling you are challenging, the legal rule the court violated, and the evidence in the record that supports your position. If a brief is missing required sections or lacks adequate legal support, the court may decline to consider the arguments at all.
If you are filing on paper rather than electronically, make sure any handwritten document is legible. Courts aren’t obligated to interpret unclear handwriting, and illegible portions may be treated as though they don’t exist. Typed filings are always the safer choice.
