If you’ve ever lost ten minutes debating whether “to” gets a capital letter in a motion title, you’re not alone. Bluebook title case looks simple, until you’re in the middle of a brief with citations, headings, and case names that all need consistent capitalization. Mastering these Bluebook citation rules is essential for trial-level briefs and appellate filings alike. While scholarly writing follows different norms, practitioners should understand Bluepages vs Whitepages distinctions to ensure their legal citation format meets professional standards.
This guide gives you a practical set of rules you can apply fast. It also includes copy-paste “Wrong → Right” examples you can drop into briefs and memos without second-guessing.
As of February 2026, the current edition is the Bluebook (22nd ed.), released in May 2025 (see a library summary of updates in Bluebook 101: Major Changes in the 22nd Edition).
The Baseline Rule: Table T6 Controls Legal Capitalization Rules in Bluebook
When lawyers say “Bluebook title case,” they’re usually talking about Table T6. T6 is where the Bluebook outlines legal capitalization rules for titles in the broader legal citation format used across common items like case names, court documents, article titles, and book titles. These Bluebook citation rules help maintain a professional appearance. In plain English, T6 follows a “capitalize the important words” approach.
Here’s the working version you’ll use most days:
- Capitalize major words (nouns, pronouns, verbs, adjectives, adverbs, and subordinating conjunctions).
- Lowercase short connecting words (articles, coordinating conjunctions, and most prepositions), unless they’re the first or last word.
- Capitalize the first word after a colon in a title.
In addition, title case is only half the battle in citations. Typeface rules matter, too. Under Rule 2.1, case names and many titles appear in italics in citation sentences (a clear summary appears in Tarlton Law Library’s typeface conventions guide).
Gotcha: Legal capitalization rules answer “what gets capitalized.” Rule 2.1 answers “what gets italicized.” You often need both.
If you want a quick refresher on how Bluebook compares to other title-case systems you may have used before, this overview helps: comparison of title case styles including Bluebook.
Bluebook title case cheat sheet (brief-friendly)
Use this table as a fast check while you draft. It tracks Table T6’s everyday effect without trying to reproduce the Bluebook’s full word lists.
| What you’re deciding | Use uppercase for | Keep lowercase for | Common notes |
|---|---|---|---|
| Most titles and headings | Nouns, verbs, adjectives, adverbs, pronouns | a, an, the; and, but, or, nor; short prepositions (of, in, on, to, for) | Always capitalize first and last word |
| After punctuation | First word after a colon | Minor words after commas | Treat hyphenated parts as separate words |
| Case names (Rule 10 + T6) | Major words in party designations | v.; of; and; the | Use case name abbreviations; abbreviate party designations per Rule 10.2 and T6 |
Following these legal capitalization rules ensures that party designations look uniform across all court documents. These rules apply regardless of whether the filing is in a state or federal venue.
Now, copy-paste examples. Each pair is formatted the way your brain catches errors during editing.
Wrong → Right
Motion To Dismiss → Motion to Dismiss
Memorandum Of Law In Support → Memorandum of Law in Support
Brief In Support Of Summary Judgment → Brief in Support of Summary Judgment
Wrong → Right
The Duty Of Care In Negligence → The Duty of Care in Negligence
A Study on Due Process → A Study on Due Process
Terms And Conditions of Release → Terms and Conditions of Release
Wrong → Right
State of New York vs. Smith → State of New York v. Smith
In Re Marriage Of Johnson → In re Marriage of Johnson
Brown V. Board of education → Brown v. Board of Education
The pattern is consistent: keep the “glue words” small, but don’t downcase the first or last word even if it’s normally minor.
Copy-paste examples by legal writing context (Rules 10, 15, 16, and Table T6)
Different sources in your brief can look similar on the page, but the Bluebook citation rules treat them under different rule sets. Use the right bucket, then apply title case.
Case names in briefs and citations (Rule 10, especially Rule 10.2)
For capitalization inside a case name, you still follow Table T6, but case names also raise two extra issues: “v.” formatting and party-name shortening. Under Rule 10, you format case names using “v.” (not “vs.”). Under Rule 10.2, and specifically Rule 10.2.1 for case name abbreviations, you abbreviate and omit words in party names when it stays clear. Many courts expect this, and law school journals almost always do. For approachable explanations with examples, see Suffolk Law’s Bluebook guide on cases (Rule 10).
When citing U.S. Supreme Court cases, prioritize the official reporter such as United States Reports, and include a parallel citation to unofficial reporters like the Supreme Court Reporter or United States Supreme Court Reports, Lawyers’ Edition if required by local court rules. For circuit courts of appeals, cite to the Federal Reporter (F., F.2d, F.3d), where a pinpoint citation to specific pages is essential. State court decisions often require the official reporter if available, alongside a parallel citation to a regional reporter such as P.3d; check local court rules for parallel citation preferences in those state court decisions. District court opinions typically appear in the Federal Supplement, again emphasizing the need for precise pinpoint citation.
For unpublished opinions and slip opinions, include the docket number and access information from databases like Westlaw and LexisNexis. After providing a full citation, transition to a short form citation for subsequent references. Use an id. citation (or just “id.”) for immediately following citations to the same source, and supra and hereinafter for non-immediate repeats, following Rule 10.9 precisely. A short form citation with id. citation keeps your brief concise while maintaining accuracy.
Wrong → Right
United States Versus American Library Association → United States v. American Library Ass'n
National Association of Realtors v. Department of Justice → Nat'l Ass'n of Realtors v. Dep't of Just.
International Business Machines v. City of New York → Int'l Bus. Machs. v. City of N.Y.
Wrong → Right
In Re The Estate Of Garcia → In re Estate of Garcia
Ex Rel Smith v. Jones → Smith ex rel. Jones v. Brown
Keep an eye on procedural phrases. They may have their own typeface treatment in citations (Rule 2.1), even while you apply the same title case logic to the words themselves.
Titles of court documents (motions, orders, memos) in citations and headings
Court document titles often appear in a brief’s headings, record cites, or case history. The Bluebook generally treats these like other titles for capitalization purposes, so Table T6 gets you most of the way there.
Wrong → Right
Plaintiff's Motion For Preliminary Injunction → Plaintiff's Motion for Preliminary Injunction
Order Granting Defendant's Motion To Dismiss → Order Granting Defendant's Motion to Dismiss
Declaration Of Jane Doe In Support Of Motion → Declaration of Jane Doe in Support of Motion
If your local court rules require sentence-case headings, follow the court rule. When the court is silent, consistent title case usually reads cleaner.
Article and book titles in citations (Rules 16 and 15)
For secondary sources, Bluebook capitalization is still Table T6, but the governing rules are different: Rule 16 for periodicals (articles) and Rule 15 for books and reports. Statutory compilations like the United States Code follow Rule 13, often in public domain format via Westlaw and LexisNexis or the Government Publishing Office. A library guide like UC Davis’s journals and newspapers Bluebook guide can help when you’re also juggling italics, small caps, and publication details, especially for United States Code titles.
Copy-paste examples for titles (capitalization only):
Wrong → Right
The Future Of ai In Law → The Future of AI in Law
An Empirical Study Of Pleading Standards → An Empirical Study of Pleading Standards
Federalism And The Separation of Powers → Federalism and the Separation of Powers
Wrong → Right
The Bluebook: a Uniform System of Citation → The Bluebook: A Uniform System of Citation
Principles of Contract law → Principles of Contract Law
One last detail: don’t “fix” quoted titles into sentence case when you cite them. Apply T6 title case even if the source uses different headline styling, unless a specific rule tells you otherwise.
Conclusion
Bluebook title case gets easier once you treat it like a courtroom habit: consistent, repeatable, and a little picky on purpose. Start with Table T6, then match the context, case names under Rule 10, books under Rule 15, and articles under Rule 16. Keep a short set of “Wrong → Right” pairs nearby while you edit. After a week, you’ll catch most title-case issues on sight, and your headings and citations will look like they belong together.
