The "Burden of Proof" is a legal principle that determines which party in a dispute is responsible for providing evidence to support their claims. In most cases, the party making an assertion, such as the plaintiff in a civil case or the prosecution in a criminal case, carries this burden. This means they must present sufficient evidence to convince the judge or jury of their position. In legal contexts, the burden of proof can vary depending on the type of case. For example, in criminal cases, the prosecution must prove the defendant's guilt "beyond a reasonable doubt," while in civil cases, the standard is usually "preponderance of the evidence," meaning the evidence must show that something is more likely true than not.
