Depending on the jurisdiction and type of action, the legal standard to satisfy the burden of proof in U.S. litigation may include, but is not limited to: beyond a reasonable doubt in criminal law. clear and convincing evidence in fraud in will disputes. preponderance of the evidence in most civil cases.

A "burden of proof" is a party's duty to prove a disputed assertion or charge, and includes the burden of production (providing enough evidence on an issue so that the trier-of-fact decides it rather than in a peremptory ruling like a directed verdict) and the burden of persuasion (standard of proof such as preponderance of the evidence).
