Preponderance Of The Evidence

The burden of proof required in a civil (non-criminal) action to convince the court that a given proposition is true. The plaintiff must convince the judge or jury by a preponderance of the evidence that the plaintiff's version is true -- that is, over 50% of the believable evidence is in the plaintiff's favor. Compare: reasonable doubt
