A more thorough explanation:

An alternative dispute resolution service is an organization or place that provides opportunities for resolving conflicts between parties without the need for lengthy and expensive litigation. These services are designed to offer an alternative to traditional court proceedings and can include mediation, arbitration, and negotiation.

For example, the American Arbitration Association (AAA) and JAMS are both alternative dispute resolution providers that offer services worldwide. They provide information and resources to help parties decide if alternative dispute resolution is a better fit for their needs than a conventional trial.

These examples illustrate how alternative dispute resolution services can help parties resolve disputes in a more efficient and cost-effective manner. By offering a range of options for resolving conflicts, these services can help parties avoid the time and expense of traditional court proceedings.
