“Onus probandi” is a legal term in Latin that means “burden of proof” in English. It is the responsibility or obligation placed on one party in a legal proceeding to provide enough evidence in support of their claims or allegations. In a legal case, the burden of proof usually rests on the party that makes the affirmative claim or assertion. This means that the party making a claim must present sufficient evidence to convince the court or the jury that their claim is true or valid. The burden of proof can vary based on the type of case and the legal standards applied, such as “beyond a reasonable doubt” in criminal cases or “preponderance of the evidence” in civil cases.
