Legal Definitions - probatio viva

Definition: Probatio viva is a Latin term that refers to a live test or demonstration used to prove the truth or validity of a claim or argument. It is a form of evidence that involves presenting witnesses or experts who can testify to the accuracy of a statement or the effectiveness of a product or process.

Example: In a court case, a probatio viva might involve calling witnesses to testify about what they saw or heard related to the case. For example, if someone is accused of stealing a car, witnesses who saw the person driving the car or who saw the car being taken might be called to testify. In a scientific experiment, a probatio viva might involve conducting a live demonstration of a new technology or treatment to show that it works as intended.

The examples illustrate how probatio viva is used to provide evidence that supports a claim or argument. By presenting live testimony or demonstrations, it can be easier to convince others of the truth or validity of a statement or product.
