Legal Briefs We Write

Our legal brief writing services cover the six brief categories solo litigators, in-house litigation teams, and small-to-mid trial firms order most often. Engagements scope at the brief level for fixed-fee deliverables, or at the workstream level for ongoing briefing capacity. Cite-checking is bundled into every engagement and also available as a stand-alone service.

Appellate Briefs

Opening briefs, answering briefs, reply briefs, amicus briefs, and supplemental briefs in state and federal appellate courts, plus petitions for writ of certiorari (cert petitions), petitions for rehearing and rehearing en banc, and writ and mandamus briefing where interlocutory review is sought before final judgment. Standard of review identified, controlling authority lined up, adverse precedent distinguished, and the formatting rules of the specific appellate court followed precisely.

Motion Briefs

Memoranda of law in support of and in opposition to motions to dismiss, motions for summary judgment, motions in limine, motions to compel, motions for class certification, and Daubert motions. Argument structured under the controlling court's procedural rule and the substantive standard for the motion type.

Trial & Pre-Trial Briefs

Pre-trial briefs, trial briefs, mediation statements, jury instruction briefs, and bench briefs on contested evidentiary points. Tailored to the trial schedule, the lead lawyer's argument plan, and the controlling jurisdiction's pattern jury instructions.

Memoranda of Law

Internal memoranda of law for case-strategy use, settlement-position memos, demand-letter supporting memos, and memoranda of points and authorities for filings that require them under California Rules of Court, rule 3.1113 or analogous state rules.

Reply & Opposition Briefs

Reply briefs answering substantive opposition, opposition briefs to motions, sur-replies where leave is granted, and supplemental briefing on issues identified at oral argument or by court order. Tightly focused on the points the prior briefing left contested.

Cite-Checking & Bluebook

Cite-checking of finished briefs for Bluebook or ALWD format, signal accuracy, parenthetical accuracy, pin-cite verification, and confirmation that each authority is still good law. Stand-alone cite-checking engagements available without rewriting the underlying argument.

What a Brief Is

What a Legal Brief Actually Is

A legal brief is a written argument that frames the dispositive issue, organizes the relevant facts, lines up the controlling authority, and structures each argument under IRAC or CREAC so a judge with a crowded docket can follow the chain of reasoning to the requested relief. Motion briefs, appellate briefs under Federal Rule of Appellate Procedure 28, trial briefs, and bench briefs each carry their own formatting and word-limit rules; our full guide to what a legal brief is and how each type is structured walks through the anatomy court by court. Our brief writers run this stack as their full-time work and pair every draft with attorney supervision before the deliverable returns for filing.

Brief Anatomy

What Each Brief Contains, From Caption to Conclusion

The five-part anatomy below is the structural spine our writers run through on every brief. Court-specific requirements (page limits, certificate of compliance, specific section ordering) layer on top, and the writer adapts the spine to the controlling jurisdiction's rules.

  1. I

    Caption, Tables, Statement of Issues

    Court caption per Federal Rule 10(a) or the controlling state rule; table of contents and table of authorities (appellate); statement of jurisdiction (appellate); statement of issues presented or questions presented framed for the dispositive issue.

  2. II

    Statement of the Case & Statement of Facts

    Procedural posture summary; statement of facts organized to support the argument, with record citations on every assertion. Adverse facts addressed cleanly rather than ignored, judges read briefs that hide bad facts as untrustworthy.

  3. III

    Standard of Review (Appellate) or Legal Standard

    Standard of review identified for each issue (de novo, abuse of discretion, clear error, substantial evidence) with controlling authority. Trial-level briefs identify the substantive legal standard for the motion type instead.

  4. IV

    Argument

    Each argument structured under IRAC or CREAC, with point headings that frame the proposition. Controlling authority cited with parenthetical explanation; adverse authority distinguished or addressed; policy arguments where the law is genuinely open.

  5. V

    Conclusion, Certificates, Cite-Check

    Conclusion stating the relief requested precisely; certificate of compliance and certificate of service per the controlling court's rule; final Bluebook or ALWD cite-check with each authority verified as still good law.

Engagement Flow

How a Brief Writing Engagement Runs

Five-step flow from quote intake to deliverable. Source materials move through an encrypted client portal, a senior brief writer drafts the brief, a peer cite-check pass runs against current case law, and the deliverable returns to your firm for review under your Rule 5.3 supervision, signature, and filing.

Five-step legal brief writing workflow from quote intake and writer match through encrypted handoff, drafting and peer cite-check pass, to deliverable returned for the engaging firm or pro se litigant to sign and file
  1. 1

    Quote intake

    Send the case caption, the brief type, the controlling jurisdiction, the deadline, and the issues to brief through the quote form. Quotes return within one business day.

  2. 2

    Writer match

    We pair the engagement with a senior brief writer credentialed for the controlling court and the substantive area, and a peer cite-checker for the QA pass.

  3. 3

    Secure handoff

    Record cites, deposition transcripts, lower-court rulings, and party briefs move through an encrypted client portal. Access is provisioned to the named writer only.

  4. 4

    Draft and cite-check

    First draft prepared by the writer; peer cite-check run against current case law before any revision cycle. Deliverable then returns to the engaging firm for Rule 5.3 supervision, signature, and filing.

  5. 5

    Returned for filing

    Final deliverable returned to your firm or you for filing. The engaging firm or the pro se litigant signs and files; Legal Tank does not file briefs under its own signature.

Engagements

What Litigators Say About the Engagement

Five-star feedback from solo appellate practitioners, litigation partners, and in-house teams that hired our brief writers for a single brief or an ongoing briefing workstream. Each engagement ran with a senior brief writer on the file and a peer cite-check pass before the deliverable returned through the encrypted client portal for the engaging counsel to sign and file.

Took on a federal appellate matter mid-cycle when our prior counsel withdrew, and the opening brief was due in nineteen days. Their brief writer rebuilt the statement of facts from the trial record, framed the dispositive issue cleanly, and lined up controlling Sixth Circuit authority with parenthetical explanations on every cite. Peer cite-check against Westlaw, returned to my office for review, signed and filed under my own bar number on day eighteen. Panel ruled in our favor on the issue we briefed.

Sixth Circuit Opening Brief

Our litigation team had a summary judgment opposition due during a trial week. Their writer drafted the memorandum of law in opposition, distinguished four adverse circuit decisions, and structured the genuine-issue-of-material-fact argument around the deposition transcripts we sent through the portal. Cite-checked against current case law, peer review pass cleared the brief, returned in time for our partner to review, sign, and file. We won the motion.

Summary Judgment Opposition

Solo plaintiff-side employment practice and I cover federal MSJ briefing about ten times a year. Their writer became my go-to for the substantive memo of law on retaliation and discrimination claims. Drafts come back tight, IRAC structure clean, statement of facts keyed to the deposition cites, and the cite-check is filing-ready. I sign and file under my own bar number; they handle the heavy drafting bench.

Rule 5.3 & Filing

We Draft and Cite-Check; Your Firm or You Sign and File

Our brief writers prepare the deliverable as drafting work product, then a peer cite-check pass runs against the actual case law before the brief returns through the encrypted portal. Every deliverable returns signature-ready: formatted to the controlling court's rules, cite-checked against current case law, and built around your signature block so it is ready for your bar-numbered signature without reformatting. The brief itself is signed and filed by the engaging firm under its own bar number, or by the pro se litigant directly under the litigant's signature. Legal Tank does not sign briefs, does not file briefs, and does not enter an appearance. For a pro se litigant, we prepare self-help documents, not legal advice, and you remain responsible for reviewing, signing, and making any ghostwriting disclosure your court requires.

Rule 5.3 supervision sits with your firm

When a law firm engages us, the engaging attorney is the supervisor of record under ABA Model Rule 5.3. The brief writer's work product is returned to the firm, and the firm files under its own bar number, certificate of compliance, and certificate of service.

Senior brief writer + peer cite-check

Inside Legal Tank, every brief runs a senior brief writer and a peer cite-check pass before it leaves the portal. The cite-check verifies every cite against the current published case law, and the writer is matched to the controlling court at quote stage. Sign-off and filing are handled by the engaging firm.

FAQ

Common Questions About Legal Brief Writing

Can AI write me a legal brief?
Generative AI can produce a first-pass legal brief from a set of facts and a target jurisdiction, and the output will read fluently, but the draft is a starting point and not a filing-ready document. AI hallucinates citations to cases that do not exist or that say the opposite of the proposition cited, fabricates statutory subsections, and routinely misses controlling authority that points the other way. The Mata v. Avianca, Inc. (S.D.N.Y. 2023) sanction order against attorneys who filed a ChatGPT-drafted brief with fabricated cases is the leading published example. The American Bar Association's Formal Opinion 512 (July 2024) confirms that lawyers using generative AI tools remain bound by Model Rule 1.1's competence duty and must independently verify any AI-produced legal text. Our brief writers use AI upstream for clause libraries and structure suggestions, then a credentialed writer drafts the brief, runs Bluebook cite-checking against the actual case law, and a peer cite-check pass runs before the deliverable returns to the engaging firm or pro se litigant for signature and filing.
Is it difficult to write a legal brief?
Writing a legal brief is difficult because it asks the writer to do five things at once: frame the dispositive legal issue, organize the relevant facts to support the argument, identify the controlling authority and distinguish adverse cases, structure each argument under IRAC or CREAC, and cite-check the entire instrument under Bluebook or ALWD format. The procedural rules of the controlling court add a sixth layer (page or word limits, formatting requirements, certificate-of-service and certificate-of-compliance pages). Where the brief is appellate, the standard of review attaches a seventh layer that determines how persuasive the argument has to be. Our brief writers run this stack as their full-time work, layer in a peer cite-check against the actual case law, and return the deliverable to the engaging firm or the pro se litigant for review under Rule 5.3 supervision, signature, and filing.
What types of legal briefs do you write?
We write appellate briefs (opening, answering, reply, amicus, and supplemental), motion briefs and memoranda of law (motions to dismiss, summary judgment, in limine, to compel, class certification, and Daubert), trial and pre-trial briefs, mediation statements, bench briefs, and reply and opposition briefs. We also cite-check a finished brief you already have for Bluebook or ALWD format as a stand-alone engagement. Each brief is drafted for the controlling court's procedural rules and the substantive standard that governs the motion or appeal.
How much does a legal brief cost?
Each brief is priced as a flat fee, not an hourly rate, so the cost is fixed and known before any drafting begins. The fee tracks the brief type, the number of issues, the size of the record, and the deadline: a single-issue motion brief is scoped differently from an appellate opening brief built on a full trial record. Send the brief type, jurisdiction, issues, and deadline through the quote form and a flat quote comes back within one business day, with no payment until you approve it.
How fast can you get a legal brief written?
Turnaround depends on the brief type and the size of the record, and rush deadlines are accommodated. Tell us your filing date at the quote stage and we confirm whether the timeline fits before you engage, rather than promising a date we cannot hold. A single-issue motion brief turns faster than an appellate brief that requires reading a full record and mapping the standard of review for each issue.
What is the difference between a trial brief and an appellate brief?
A trial brief argues to the trial court and can introduce evidence and cite fresh authority to support a motion or a contested point at trial, so building the factual record is part of the argument. An appellate brief is confined to the record already made below and applies the governing standard of review (de novo, abuse of discretion, clear error, or substantial evidence) to persuade a reviewing court that the lower court did or did not err. The appellate brief cannot add new facts; it argues from the record and the standard. We draft both, each matched to the court and the standard that governs the filing.
How long does it take to receive a finished legal brief?
Finished briefs return within a qualitative business-day range that tracks the brief type and the size of the record: a single-issue motion brief comes back in a shorter window than an appellate brief that requires reading a full trial record and mapping the standard of review for each issue. Rush turnaround is available when a filing deadline is close. This finished-work delivery window is separate from the quote turnaround, which returns within one business day of intake so you know the timeline before you engage.
How is a memorandum of law different from a brief?
A brief is an advocacy document: it argues to persuade a court to rule a particular way on a motion or an appeal. A memorandum of law can serve either purpose depending on context. A supporting or opposing memorandum of law, often styled a memorandum of points and authorities, is filed with a motion and argues to persuade the court, so in that setting it functions as the motion brief itself. An internal or office memorandum of law, by contrast, is objective: it analyzes the strengths and weaknesses of a legal position for the client or the file rather than advocating one outcome. We draft both the persuasive supporting memoranda and objective internal memoranda.
Is outsourcing brief writing to a non-lawyer the unauthorized practice of law?
Not when it is structured correctly. A licensed attorney who engages a drafting service stays the supervisor of record under ABA Model Rule 5.3 on nonlawyer assistance, reviews the work product, and signs and files the brief under their own bar number. The drafting service does not sign the brief, does not enter an appearance, and does not give legal advice. For a pro se litigant, we prepare self-help documents that the litigant reviews, signs, and files, subject to any ghostwriting disclosure the court requires.
