This chapter presents an overview of the alternative dispute resolution (ADR) options available to parties to a dispute in England and Wales, outlining the most commonly used processes. A lawyer should be familiar with the range of ADR options and be able to advise a client on appropriate use of ADR. This includes familiarity with each process, when it should be used, who might attend, and key strengths and weaknesses. ADR options can be broadly divided into processes that are adjudicative (where a third party takes a decision) and those which are non-adjudicative (where the parties approve any proposed settlement). The main non-adjudicative options are negotiation and mediation. The main difference between the two is that a negotiation is normally conducted by lawyers, whereas a mediation includes a neutral third party. Meanwhile, the main adjudicative options are arbitration and expert determination.
