standard of proof

  • Degree of proof required. In criminal cases, prosecutors must prove a defendant's guilt "beyond a reasonable doubt." The majority of civil lawsuits require proof "by a preponderance of the evidence" (50 percent plus), but in some the standard is higher and requires "clear and convincing" proof.
