What describes individuals who are not directly involved in a legal matter?

The term that accurately describes individuals who are not directly involved in a legal matter is "third parties." Third parties are individuals or entities who may be affected by the outcome of a legal matter or have an interest in it, but they do not have a direct stake or relationship to the parties involved in the legal proceedings. For example, in a contractual dispute between two businesses, any outside parties that may also have an interest or stake in the contract’s outcome, such as suppliers or customers, would be considered third parties.

Organizations refer to groups or entities organized for a specific purpose, but they could be directly involved in legal matters depending on the context. Authorized representatives usually refer to individuals who have the legal authority to act on behalf of another party in a legal matter, thereby being directly involved. Firm clients clearly refer to individuals or entities who have engaged the services of a law firm, placing them directly into the legal matter at hand. Thus, "third parties" distinctly captures those individuals who are peripheral to the legal issue, rather than central characters within it.
