A more thorough explanation:

COUNTER

A counter is a historical term used to describe an advocate or professional pleader who orally recites for a client in court. They were a group of people who practiced before the Common Bench.

During the medieval period, a counter was a common sight in courtrooms. They would stand beside their client and recite their case to the judge. For example, if a person was accused of a crime, the counter would argue on their behalf and try to prove their innocence.

Another example of a counter's role was in land disputes. If two parties were fighting over a piece of land, the counter would recite the history of the land and try to prove their client's ownership.

The examples illustrate how a counter would act as an advocate for their client in court. They would use their oratory skills to argue on behalf of their client and try to prove their case. The role of a counter was important in medieval times when many people were illiterate and needed someone to speak for them in court.
