Adhesion contract

one-sided contract

A standard form contract (sometimes referred to as an adhesion contract or boilerplate contract) is a contract between two parties that does not allow for negotiation, i.e. take it or leave it. It is often a contract that is entered into between unequal bargaining partners, such as when an individual is given a contract by the salesperson of a multinational corporation. The consumer is in no position to negotiate the standard terms of such contracts and the company's representative often does not have the authority to do so.
