Standard of Proof is a criterion used in civil court cases to specify the threshold for guilt. Typically, Standard of Proof specifies that the evidence against the defendant must be 51% or higher to prove their guilt. Unlike criminal cases, where the jury/judge must decide guilt or innocence beyond a reasonable doubt, Standard of Proof is the more lenient side of the law. For example, if a psychologist were to be investigated for a complaint, the evidence against them must say there is a 51% or more chance that the psychologist is guilty before they would lose their license.
