Responsibility for Proof-Plaintiff's Claim[s], Cross Claims, Counterclaims-Preponderance of the Evidence is the burden of proof that each party must meet in litigation. The preponderance of the evidence standard requires that one party provide evidence which more likely than not proves their case. The party with the burden of proof must prove each element of their claim by a preponderance of the evidence. This means that they must provide evidence which is more convincing than the evidence provided by their opponent. There are two types of Responsibility for Proof-Plaintiff's Claim[s], Cross Claims, Counterclaims-Preponderance of the Evidence: 1. Plaintiff's Claim: The plaintiff in a lawsuit has the burden of proof to prove their claim by a preponderance of the evidence. The plaintiff must prove each element of their claim by a preponderance of the evidence. 2. Cross Claims, Counterclaims: When another party files a cross-claim or counterclaim against the plaintiff, the plaintiff must still prove their claim by a preponderance of the evidence. However, the plaintiff must also prove their opponent's claim or counterclaim by a preponderance of the evidence. This means that the plaintiff must provide evidence which is more convincing than the evidence provided by their opponent.
