Which of the following terms is considered a possible resolution outside of court?

The term that represents a possible resolution outside of court is "dispute resolution." This encompasses various methods that parties may use to settle their disputes without resorting to litigation, which can be costly and time-consuming. Dispute resolution includes mechanisms such as mediation, arbitration, and negotiation, allowing both parties to reach an agreement with the assistance of a neutral third party or through direct communication.

In contrast, the other options refer to processes that occur within the judicial system or involve formal legal actions. A lawsuit represents a legal action taken in court to resolve a dispute, a court hearing is a formal proceeding where evidence and arguments are presented in front of a judge or jury, and a subpoena is a legal document that compels a person to appear in court or produce evidence. Each of these choices is inherently linked to court proceedings, making them unsuitable as methods for resolving disputes outside of that context.
