Actori Incumbit Onus Probandi: The Essential Legal Principle of Burden of Proof
Definition & Meaning
The phrase "actori incumbit onus probandi" translates to "the burden of proof is on the plaintiff." In legal terms, this means that the person who brings a lawsuit (the plaintiff) is responsible for proving their claims. This principle is fundamental in both civil and criminal law, as it establishes who must provide evidence to support their case in court.
