The burden and standard of proof mandates which party is responsible for convincing the courts and to what extent that party needs to justify their claims. Preponderance of evidence is one of these legal standards of proof.
But, during all this time the burden of proof, the risk of non-persuasion, remains with the plaintiff, except as to affirmative defenses, etc. The burden of evidence is simply the burden of making or meeting a prima-facie case.
