In a civil case at the trial level, the plaintiff’s name comes first and the defendant’s name comes second, so “Smith v. Jones” tells you Smith sued Jones. That’s the default answer to whether the plaintiff or defendant comes first in a case name, but it isn’t the whole picture. Criminal cases put the government first. Family law, immigration, and Supreme Court cases use different labels entirely. And on appeal, the order can flip.
Civil Cases: Plaintiff First
Federal Rule of Civil Procedure 10 requires the title of a complaint to name all the parties, with the plaintiff listed first and the defendant listed second.1Legal Information Institute (Cornell Law School). Rule 10 Form of Pleadings The plaintiff is the party who filed the lawsuit; the defendant is the party being sued. That’s the whole reason for the order. Whoever brought the case leads the caption.
The “v.” between the names is short for “versus.” Later filings in the same case don’t need to spell out every party. Once the complaint has named everyone, subsequent papers can name the first party on each side and refer to the rest generally.1Legal Information Institute (Cornell Law School). Rule 10 Form of Pleadings When several people are on the same side, you’ll often see “et al.” after the lead name, Latin for “and others.” A case with a dozen plaintiffs suing one company might be captioned “Smith, et al. v. Jones Corporation.”
Criminal Cases: The Government First
Criminal cases don’t follow the plaintiff-first rule because there’s no private plaintiff. The government brings the charges, so the government’s name always leads. In federal court, that reads as “United States v. [Defendant].” State practice varies:
- Most states use “State v. [Defendant].”
- New York and California use “People v. [Defendant].”
- States styled as commonwealths use “Commonwealth v. [Defendant].”
A crime victim may testify, but the case belongs to the prosecuting authority. You won’t see the victim’s name in the caption.
When It’s Petitioner and Respondent Instead
Some proceedings don’t use “plaintiff” and “defendant” at all. The party who starts the case is the petitioner, and the other side is the respondent. Divorce and custody matters, immigration hearings, and requests for court orders such as restraining orders typically use this terminology. The naming order works the same way: petitioner first, respondent second.
The U.S. Supreme Court uses this labeling too. The party who asked the Court to hear the case is the petitioner; the other side is the respondent.2United States Court of Appeals for the Third Circuit. Definitions That matters for how case names look, as the next section explains.
Why the Order Can Flip on Appeal
Federal Rule of Appellate Procedure 12(a) tells circuit clerks to docket an appeal “under the title of the district-court action,” so most federal appeals keep the trial court’s order intact.3United States Courts. Federal Rules of Appellate Procedure The plaintiff still comes first even though they may be the one who lost and is now appealing.
The Supreme Court works differently. Whichever party petitioned for review is listed first, regardless of who was the plaintiff at trial. If the defendant lost on appeal and asked the Supreme Court to take the case, the defendant’s name now leads.2United States Court of Appeals for the Third Circuit. Definitions That’s how a case that began as “Smith v. Jones” at the trial court can appear as “Jones v. Smith” in the Supreme Court reports. Same dispute, same parties, different order because the losing side became the petitioner.
State appellate courts don’t handle this uniformly. Some preserve the trial court caption. Others move the appellant to the front. If you’re reading an appellate opinion and the names appear reversed from the record below, this is almost always why.
Things That Don’t Change the Order
A few common situations look like they might rearrange the caption but don’t.
Counterclaims
When a defendant files a counterclaim, they’re pursuing their own claim against the plaintiff. The caption doesn’t change. “Smith v. Jones” stays “Smith v. Jones” even if Jones is now suing Smith right back within the same case. Federal rules actually require certain counterclaims: if the defendant’s claim arises out of the same events as the plaintiff’s lawsuit, it’s compulsory and has to be raised in the answer or it’s lost.4Office of the Law Revision Counsel. 28 USC App Fed R Civ P Rule 13 Counterclaim and Cross-Claim Claims unrelated to the original dispute are permissive; the defendant can raise them but doesn’t have to. Either way, the plaintiff’s name stays first at the trial level.
Doe Defendants
When a plaintiff knows they were harmed but doesn’t yet know who did it, many state courts allow fictitious “Doe” placeholder names, producing captions like “Smith v. Doe 1, Doe 2, et al.” Once discovery reveals the real identity, the plaintiff amends the complaint to substitute the actual name. Federal courts generally don’t permit fictitious defendants. The plaintiff’s position at the front of the caption doesn’t change either way.
In Rem Cases
Some cases are filed against property rather than a person. Civil forfeiture and certain admiralty proceedings produce captions like “United States v. $50,000 in U.S. Currency.” The government still leads; the “defendant” is simply the thing rather than a person.
A Quick Way to Read Any Caption
Ask two questions when you see a case name. First, what kind of case is it? A civil case at the trial level puts the plaintiff first. A criminal case puts the government first. A petition-based proceeding puts the petitioner first. Second, what stage is it at? If it’s a Supreme Court decision, the first name is the party who asked the Court to hear the case, which may or may not be the original plaintiff. Answer those two questions and the order of the names will tell you exactly who is who.
