Liaison interpreting is one mode of interpretation. It originates in the business sector, in the form of negotiation through a proxy-person, whose expertise and duty is to enable communication. The interpreter provides an on-the-spot "liaison" and connects the two parties, bridging language and cultural gaps.

Liaison interpreting is a facilitation work. The interpreter finds for each situation the best way to establish fluid and harmonious communication between the parties. Sensibility, perception, top-notch communication and interpersonal skills are paramount to a quality liaison, greatly contributing to the parties' fruitful negotiation.

It may be used in diplomatic relations, working lunches, trainings, informal meetings and various sorts of visits, including foreign delegations. Business negotiations and international fairs which require linguistic mediation usually make use of liaison interpreting.
