A more thorough explanation:

Definition: A co-party who responds to a petition or appeal. In family law, the person accused of committing adultery in a divorce suit.

• When a petition is filed, the respondent is the person who must respond to the allegations made in the petition.
• In a divorce case based on adultery, the corespondent is the person accused of having an affair with the spouse.
• During an appeal, the respondent is the party against whom the appeal is taken.

These examples illustrate how a corespondent is a party who must respond to a legal action or accusation made against them. In a divorce case, the corespondent is the person accused of committing adultery, and they must respond to the allegations made against them. Similarly, during an appeal, the respondent is the party who must respond to the appeal made against them.
