A type of contract, a legally binding agreement between two parties to do a certain thing, in which one side has all the bargaining power and uses it to write the contract primarily to his or her advantage.
An example of an adhesion contract is a standardized contract form that offers goods or services to consumers on essentially a "take it or leave it" basis without giving consumers realistic opportunities to negotiate terms that would benefit their interests. When this occurs, the consumer cannot obtain the desired product or service unless he or she acquiesces to the form contract.
There is nothing unenforceable or even wrong about adhesion contracts. In fact, most businesses would never conclude their volume of transactions if it were necessary to negotiate all the terms of every consumer credit contract. Insurance contracts and residential leases are other kinds of adhesion contracts. This does not mean, however, that all adhesion contracts are valid. Many adhesion contracts are unconscionable; they are so unfair to the weaker party that a court will refuse to enforce them. An example would be severe penalty provisions for failure to pay loan installments promptly that are physically hidden by small print located in the middle of an obscure paragraph of a lengthy loan agreement. In such a case a court can find that there is no meeting of the minds of the parties to the contract and that the weaker party has not accepted the terms of the contract.
