An adhesion contract (also known as a contract of adhesion) is a contract between two parties, where the terms and conditions are drafted by the party with superior bargaining power (typically a business) and the other party (typically a consumer) has little or no ability to negotiate more favorable terms and, as a result, the consumer is placed in a "take-it-or-leave it" position.
The courts carefully scrutinize adhesion contracts and will sometimes void certain provisions on the basis that the provisions are unconscionable or the product of unequal bargaining power.
