Evidentiary standards, or standards of proof, are the legal rules defining how convincing evidence must be for a judge or jury to rule in a party's favor, varying significantly between civil and criminal cases, with major types including "preponderance of the evidence" (more likely than not, >50% in civil cases) and the much higher "beyond a reasonable doubt" (for criminal convictions). They determine the quantity and quality of proof needed to establish a fact, influencing whether a claim (like negligence in a lawsuit) or a criminal accusation is proven.
