Русско-англо-русский юридический словарь

There are large areas of economic life in which the parties to contracts have such unequal bargaining positions that little real negotiation takes place. These contracts are often known as contracts of adhesion. Familiar examples of adhesion contracts are contracts for transportation or service concluded with public carriers and utilities and contracts of large corporations with their suppliers, dealers, and customers. (Britannica)

An unconscionable transaction is one in which no right-minded person would ever make, and no fair-minded person would ever accept. To prove an unconscionable transaction one must prove that: 1. the bargain was made without regard to one's future 2. there was an inequality in the bargaining position of the two parties.
