Preponderance of the Evidence:
“The parties must persuade you, by the evidence presented in court, that what they are required to prove is more likely to be true than not true. This is referred to as “the burden of proof.” After weighing all of the evidence, if you cannot decide that something is more likely to be true than not true, you must conclude that the party did not prove it. You should consider all the evidence, no matter which party produced the evidence. In criminal trials, the prosecution must prove that the defendant is guilty beyond a reasonable doubt. But in civil trials, such as this one, the party who is required to prove something need prove only that it is more likely to be true than not true.”
Clear & Convincing Evidence:
“Certain facts must be proved by clear and convincing evidence, which is a higher burden of proof. This means the party must persuade you that it is highly probable that the fact is true. I will tell you specifically which facts must be proved by clear and convincing evidence.”
