Justipedia explains Legal English
Legal English is difficult for the average person to understand, which is why many people hire lawyers in the first place. Lawyers help people to navigate and interpret the complex language of the law.
If a person with no formal legal training tries to defend themselves in a trial, then they may struggle to keep up with the legal English that is most likely to be used during the trial.
