Pre-setttement settlement, or PreSS, is a negotiation technique that precedes and potentially facilitates a final settlement. A PreSS is distinguished by three characteristics. It is: formal (being a binding agreement), initial (being the first step of a longer process), and partial (covering only a subset of issues). PreSS provides a conceptual umbrella for several existing concepts in the negotiation literature. The what, when, and why of PreSS are delineated and examples of pre-settlement settlement are provided.
