Burden of proof is the obligation to prove the facts supporting a claim or defense in Civil Procedure. In most civil cases, the plaintiff carries it and must prove the case by a preponderance of the evidence.
Burden of proof is the party's obligation to prove the facts that support its side of a civil case. In Civil Procedure, that usually means the plaintiff has to show the court and jury that the claim is more likely true than not, which is the preponderance of the evidence standard.
This is not just a trial concept. It affects the whole lawsuit, from the complaint and answer to summary judgment and trial motions. If you are the party with the burden, you need enough admissible evidence to support each required element of the claim. If you do not, the case can fail before a jury ever hears it.
A useful way to think about it is that the burden of proof tells you who has to persuade the decision-maker. In a negligence case, for example, the plaintiff must prove duty, breach, causation, and damages. The defendant does not have to prove anything unless it raises an issue like an affirmative defense or tries to defeat the plaintiff's evidence.
Courts sometimes talk about burden shifting, but that does not mean the original burden disappears. It just means the other side has to respond once the first party has put forward enough evidence to create a real dispute. At summary judgment, this matters a lot because a judge asks whether the party with the burden has enough proof for a reasonable factfinder to rule its way. Cases like Celotex Corp. v. Catrett and Anderson v. Liberty Lobby, Inc. are often used to explain how that proof works at this stage.
The burden of proof also shapes how lawyers argue. In opening statements, a plaintiff will preview evidence to show the story is supported. In closing arguments, counsel ties that evidence together and reminds the factfinder why the burden has or has not been met. So even though the phrase sounds abstract, it shows up everywhere in civil litigation as the rule that controls who has to prove what, and how much proof is enough.
Burden of proof is one of the ideas that connects the whole Civil Procedure sequence. It explains why some motions succeed early, why some cases reach a jury, and why one side has to build a stronger record than the other.
It also helps you make sense of standards of proof. Preponderance of the evidence is the usual civil standard, while clear and convincing evidence appears in certain more demanding situations. If you know which party carries the burden and how strong the showing must be, you can predict who is likely to win a motion or trial issue.
This term shows up constantly in summary judgment and judgment as a matter of law analysis. Those doctrines are not just about whether evidence exists. They ask whether the evidence is enough for the party with the burden to survive the judge's review and get the issue to the jury, or keep a jury verdict in place. That is why this concept is so tied to litigation strategy and evidence presentation.

This is the most common civil standard tied to burden of proof. When the plaintiff has this burden, the question is whether the facts are more likely true than not, not whether the claim is certain. If you see a civil claim on an exam or in a case problem, this is usually the standard you should check first.
Summary Judgment
Rule 56 is where burden of proof becomes very practical. The moving party has to show there is no genuine dispute of material fact, and the court looks at whether the party with the burden at trial has enough evidence to go forward. This makes summary judgment a common place for burden-shifting arguments.
Prima Facie Case
A prima facie case is the basic evidentiary showing a party needs to make before the other side has to respond. In civil procedure, building a prima facie case is often the first step in meeting the burden of proof. If the plaintiff cannot establish that initial showing, the claim may fail early.
Federal Rule of Civil Procedure 50
Rule 50 deals with judgment as a matter of law, which asks whether the evidence is legally sufficient for a reasonable jury to find for the nonmoving party. That review depends on who carries the burden of proof at trial, because the judge measures the proof against the element the party must establish.
A case question or multiple-choice item may ask you to identify which party has to prove a claim, what standard applies, or why a motion succeeds before trial. Read the facts and track who is asserting the claim, then ask what that party must prove and whether the evidence is enough. In a summary judgment problem, explain whether the party with the burden has enough admissible evidence to create a genuine dispute of material fact. In a motion for judgment as a matter of law question, focus on whether the proof at trial could let a reasonable jury rule for the party carrying the burden. If you are writing about opening or closing arguments, connect the argument to persuading the factfinder that the burden has or has not been met.
Burden of proof is the duty to persuade the judge or jury on an issue, while burden of production is the duty to produce enough evidence to get the issue into the case or past a motion. They often travel together, but they are not identical. A party can meet its burden of production and still lose if it does not persuade the factfinder.
Burden of proof tells you which party has to prove a claim or defense in Civil Procedure.
In most civil cases, the plaintiff carries the burden and must prove the claim by a preponderance of the evidence.
The concept shows up in motions, discovery, opening statements, closing arguments, and trial rulings.
Summary judgment and judgment as a matter of law often turn on whether the burdened party has enough evidence to keep the issue alive.
If you know who has the burden, you can usually predict what evidence matters most and which side has the tougher path.
It is the obligation to prove the facts that support your side of a civil case. Usually the plaintiff carries that burden and must prove the claim by a preponderance of the evidence. The court uses it to decide whether the case can move forward and whether the evidence is strong enough at trial.
Most of the time, the plaintiff has the burden of proof because the plaintiff is the party asking the court for relief. But defendants can carry the burden on affirmative defenses, counterclaims, or issues the law assigns to them. So the answer depends on the claim and the specific element being litigated.
Burden of proof is the duty to prove something, while preponderance of evidence is the amount of proof usually required in civil cases. Think of burden as who has to prove, and preponderance as how much proof is enough. They work together, but they are not the same thing.
At summary judgment, the court asks whether the party with the burden at trial has enough evidence for a reasonable factfinder to rule in its favor. If that party cannot point to evidence creating a genuine dispute of material fact, the judge may end the case without a trial. That is why burden of proof is central in Rule 56 analysis.
