"Preponderance of the evidence" is a legal standard of proof that is commonly used in civil cases. It means that a party must prove that their version of the facts is more likely true than not true. In other words, the evidence presented by one side must be more convincing and persuasive than the evidence presented by the other side.
In contrast, criminal cases typically require a higher standard of proof, such as "beyond a reasonable doubt." This means that the evidence presented by the prosecution must be so strong that there is no reasonable doubt in the minds of the jurors that the defendant committed the crime.
The preponderance of the evidence standard is used in a wide variety of civil cases, including personal injury lawsuits, breach of contract cases, and disputes over property rights. It is up to the judge or jury to weigh the evidence presented by both sides and determine which side has met the preponderance of the evidence standard.
