Homonym: Third-Party (Independent)
A "Third-Party" refers to an individual or group that is not directly involved in a transaction or agreement between two primary parties. For example, in a contract between Buyer and Seller, a Third-Party could be a Mediator who helps facilitate the agreement without having a stake in the outcome.
In various contexts, such as insurance or software, a Third-Party can provide additional services or products. For instance, a Third-Party insurance provider may offer coverage options that are not available through the primary insurance company, enhancing choices for consumers.
