Alternative dispute resolution (ADR) (also known as external dispute resolution in some countries, such as Australia) includes dispute resolution processes and techniques that act as a means for disagreeing parties to come to an agreement short of litigation. It is a collective term for the ways that parties can settle disputes, with (or without) the help of a third party.
Highest form of alternative dispute resolution is an arbitration. Arbitration often requires interpreting because the parties are international and prefer to communicate in their mother languages (instead of a common language, i.e. English, French or Turkish).
Parties sometimes hire separate teams of conference interpreters to make sure that their claims are accurately translated with highest level of secrecy.
