To write an appellate brief, you identify a specific legal error the trial court made, show that it was preserved in the record and actually changed the outcome, and present that argument in the sections and format the appellate rules require. Everything in the brief must come from the existing trial record — the papers, testimony, and exhibits from the proceedings below — because appellate courts do not hear new evidence or witness testimony.1Congress.gov. Federal Rules of Appellate Procedure – Rule 10 A persuasive brief names the error, explains why it mattered, and tells the court exactly what relief you want.
What Has to Be True Before You Write
Two things can end an appeal before the first sentence of a brief: a missed filing deadline and a failure to preserve the error at trial.
An appeal starts with a short document called a notice of appeal, filed in the trial court. In federal civil cases, you have 30 days from the date judgment is entered. If the federal government is a party, the window is 60 days. In federal criminal cases, a defendant has 14 days.2Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right When Taken State deadlines vary but are equally strict. Miss this cutoff and you lose the right to appeal.
Appellate courts generally refuse to consider issues that were not raised below. If a judge admitted evidence you believe was improper and no one objected, that ruling is likely waived. The trial court deserves a chance to correct its own mistakes before a higher court is asked to. A narrow “plain error” exception exists for mistakes so obvious and damaging that they affected the fairness of the entire proceeding, but courts apply it grudgingly. Before you commit to drafting, confirm that your trial attorney made timely objections on every issue you plan to raise.
Build Only From the Record
If something is not in the trial court record, it does not exist for purposes of the appeal. The record has three components:
- The clerk’s record — all formal documents filed in the case, including the complaint, motions, court orders, and the final judgment.
- The reporter’s transcript — the verbatim account of everything said during hearings and trial.
- The exhibits — every document and physical item admitted into evidence.
In federal court, you must order the transcript in writing within 14 days of filing the notice of appeal. If you plan to argue a factual finding was unsupported by the evidence, you must include a transcript of all evidence relevant to that finding. Ordering only the portions you need saves money, but a partial order requires you to file a statement of the issues so the opposing party can designate additional portions.1Congress.gov. Federal Rules of Appellate Procedure – Rule 10 Transcripts typically run several dollars per page, and the court reporter will expect payment arrangements at the time you order.
Pick the Standard of Review for Each Issue
The standard of review is the lens the appellate court uses to evaluate what the trial court did, and it determines how hard it is to win on each issue. Misstating it signals to the judges either that you do not understand the issue or that you are trying to lower a bar that is not yours to lower. Federal rules require you to state the standard explicitly for each issue in the brief.3Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs
De Novo
Pure questions of law — how to interpret a statute or whether a contract clause is enforceable — get de novo review. The appellate court owes no deference to the trial judge and decides the question fresh.4United States Court of Appeals for the Ninth Circuit. Ninth Circuit Standards of Review – Definitions This is the most favorable standard for an appellant.
Abuse of Discretion
Discretionary rulings — admitting a piece of evidence, granting a continuance, managing discovery — are reviewed for abuse of discretion. The court asks whether the trial judge’s decision was so unreasonable that no rational judge could have made it.4United States Court of Appeals for the Ninth Circuit. Ninth Circuit Standards of Review – Definitions A high bar. You are not arguing the judge was wrong; you are arguing the decision was indefensible.
Clearly Erroneous
Factual findings made by a trial judge (rather than a jury) stand unless the reviewing court is left with a “definite and firm conviction that a mistake has been committed.”5Georgetown University Law Center. Identifying and Understanding Standards of Review Even if the appellate court would have weighed the evidence differently, it will not overturn unless the error is clear.
Substantial Evidence
Factual determinations by a jury or an administrative agency are upheld if supported by “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.”5Georgetown University Law Center. Identifying and Understanding Standards of Review If you are challenging a jury verdict on factual grounds, this standard makes the climb steep.
Show the Error Actually Changed the Outcome
Finding a legal error is only the first step. Courts distinguish between harmless errors that did not affect the result and reversible errors that did. An incorrect jury instruction on an element the jury never reached likely changed nothing. An incorrect instruction on the central disputed issue is a different story.
This is where many appeals quietly die. The appellant identifies a real mistake but cannot connect it to the result. Your brief needs to draw that line clearly: here is what the court did wrong, here is how the outcome would have been different without it. Without that connection, the court will treat the error as harmless no matter how wrong the ruling was.
The Required Sections and What Each One Does
Federal Rule of Appellate Procedure 28 lists the required sections of an appellant’s brief in a specific order.3Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs State rules follow a similar structure with local variations.
Title Page
Identifies the case name and number, the appellate court, the trial court the appeal comes from, and contact information for the filer. Some courts have specific cover-page templates or color requirements. Check local rules before formatting.
Table of Contents and Table of Authorities
The table of contents lists every heading with page numbers. The table of authorities lists every case, statute, regulation, and rule you cite, with the pages where each appears.3Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs Cases go in alphabetical order, statutes in numerical order. Judges use the table to assess the strength of your legal support at a glance, so a thin table tells them something before they reach the argument.
Jurisdictional Statement
Explains why both courts have authority over the case: the statutory basis for each court’s jurisdiction, the filing dates proving your appeal is timely, and a statement that you are appealing from a final judgment or an otherwise appealable order.3Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs Short and mechanical, but getting it wrong raises an immediate question about whether the court can hear the appeal at all.
Statement of the Issues
Each issue should be one focused sentence that weaves together the key facts and the legal rule at stake. A well-crafted issue statement suggests its own answer. Compare “Did the trial court err?” with “Did the trial court violate the Fourth Amendment by authorizing a search of the defendant’s home based solely on an anonymous, uncorroborated tip?” The second version tells the court exactly what happened and what law applies.
Statement of the Case
A neutral, chronological summary of the procedural history: when the suit was filed, what major motions were decided, what the trial court ruled, and how the case reached the appellate court. Keep it factual. Its job is to orient the judges, not persuade them.
Statement of Facts
Narrates what happened and the evidence presented at trial. It must be accurate, but the order you present facts, the details you emphasize, and the context you provide shape the court’s understanding before it reaches your legal argument. Lead with the facts most favorable to your position rather than burying them.
Every factual assertion must cite the specific location in the record where the supporting evidence appears, such as a page in the clerk’s record or a line in the transcript.3Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs Courts have declined to consider factual statements without record citations, and including facts not in the record can get portions of the brief struck. Law clerks check this early.
Summary of the Argument
A concise overview, usually one to two pages, of the main points you develop in the full argument. Federal rules require it to be more than a repetition of your section headings; it should be a self-contained roadmap that a judge could read and understand your entire theory of the case.3Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs Some judges read this section first to decide how closely to read the rest.
Argument
Organize the argument into subsections, one per issue, and lead each subsection with the applicable standard of review. Then lay out the legal rule from statutes and prior decisions and apply it to the specific facts of your case. The pattern for each issue: state the rule, show what the trial court did, explain why that violates the rule in a way that affected the outcome.
Resist the temptation to argue every possible error. A brief that raises two strong issues is more persuasive than one that raises seven, three of them weak. Weak arguments dilute strong ones and signal that you are not confident in your best points. Every legal assertion needs a citation to authority, and every factual assertion needs a citation to the record.3Legal Information Institute. Federal Rules of Appellate Procedure Rule 28 – Briefs Use headings and subheadings so judges scanning for the answer to a specific question can find it.
Conclusion
State the exact relief you want in one or two sentences. The options depend on what went wrong:
- Reversal changes the outcome, so the winner below becomes the loser.
- Vacatur wipes out the lower court’s decision so it has no further legal effect.
- Remand sends the case back to the trial court for further proceedings, often because the wrong legal standard was applied and the facts need to be reconsidered under the correct one.
In cases with multiple claims or parties, you can combine them: affirm on one claim, reverse on another, remand for a new damages calculation. Be specific. “Appellant respectfully requests that this Court reverse the summary judgment on Count II and remand for trial” tells the court exactly what you want. A vague request for “appropriate relief” does not.
Certificate of Compliance
If your brief uses a word-count limit rather than a page limit, include a short certificate stating the number of words. You can rely on your word processor’s count.6Legal Information Institute. Federal Rules of Appellate Procedure Rule 32 – Form of Briefs, Appendices, and Other Papers Omitting it can get the brief rejected at the clerk’s office.
Certificate of Service
Confirms that you sent a copy of the brief to the opposing party, with the date and method of delivery.7PACER. Frequently Asked Questions – Section: Does a Document Filed in an Appellate Court Require a Certificate of Service Electronic filing often serves the document automatically, and some courts waive the certificate in that situation. Requirements vary by circuit.
Formatting and Length
Under the Federal Rules of Appellate Procedure, a brief must be printed on 8½-by-11-inch paper with at least one-inch margins. Text is double-spaced, though block quotations and footnotes may be single-spaced. A proportionally spaced font must be at least 14-point and include serifs, though sans-serif type is permitted in headings.6Legal Information Institute. Federal Rules of Appellate Procedure Rule 32 – Form of Briefs, Appendices, and Other Papers
The default federal limit for a principal brief is 30 pages. If you use the word-count alternative, the cap is 13,000 words for a principal brief and 6,500 for a reply brief.6Legal Information Institute. Federal Rules of Appellate Procedure Rule 32 – Form of Briefs, Appendices, and Other Papers A handful of federal circuits have retained an older, slightly higher limit of 14,000 words through local rules, so always check the specific court.
Non-compliance has real consequences. A brief that violates formatting or length rules may be rejected by the clerk before a judge sees it. Courts have imposed sanctions on attorneys for ignoring spacing and font requirements, and in severe cases non-compliant briefs have led to dismissal of the appeal. Some courts allow a fix, but that is discretionary.
The Appendix
The appendix is a separate document filed with your brief containing the key portions of the trial record your arguments rely on. At a minimum it must include the relevant docket entries, the judgment or order being appealed, and the relevant portions of pleadings, findings, or opinions from below.8Legal Information Institute. Federal Rules of Appellate Procedure Rule 30 – Appendix to the Briefs You can also include transcript excerpts and exhibits.
The appendix starts with its own table of contents, and record materials inside follow chronological order. When you include transcript pages, show the original transcript page numbers in brackets. The goal is to make it effortless for judges to find the evidence supporting your arguments.
Filing and the Briefing Schedule
Most appellate courts require or strongly prefer electronic filing through a secure portal. Filing by mail or in person remains an option in some jurisdictions, but e-filing is the default in nearly all federal circuits, and the system typically serves the document on opposing counsel automatically.
The federal briefing schedule has a set rhythm. Once the record is filed, you have 40 days to serve and file your opening brief. The opposing party has 30 days after being served to file a response. If you want to file a reply, you have 21 days, and it must be filed at least 7 days before any scheduled oral argument.9Legal Information Institute. Federal Rules of Appellate Procedure Rule 31 – Serving and Filing Briefs Courts can adjust these deadlines and extensions are possible for good cause, but counting on extra time is risky.
