A more thorough explanation:

Definition: A lawful man, also known as legalis homo, is a person who has full legal capacity and rights. They have not been deprived of any rights in court due to outlawry, excommunication, or infamy. A lawful man can serve as a juror and swear an oath. They are considered "right in court."

Examples: A person who has not been convicted of a crime and has not been excommunicated from their church is considered a lawful man. They have the right to vote, serve on a jury, and make legal agreements.

Another example would be a person who has been convicted of a crime but has served their sentence and has had their rights restored. They are once again considered a lawful man and have full legal capacity and rights.

These examples illustrate that a lawful man is someone who has not been deprived of their legal rights and can participate fully in legal proceedings.
