A more thorough explanation:

Disputatio fori is a Latin term used in Roman law to refer to the practice of legal advocacy or argument before a court.

An example of disputatio fori is a lawyer presenting arguments and evidence in a court of law to defend their client in a criminal case. Another example is a lawyer presenting arguments and evidence in a civil case to prove their client's case.

These examples illustrate how disputatio fori involves the presentation of arguments and evidence in a court of law to persuade a judge or jury to rule in favor of one's client.
