A contract that so strongly favors one party or so unfairly restricts another, that it creates a presumption that one party had no choice when entering into it. If a court determines that the contract is overly unfair, it may refuse to enforce the agreement against the disadvantaged party. An example of a contract of adhesion might be a form contract provided by an unethical leasing company. Adhesion contracts are often evidenced by the comparative strength of the parties-- for example, a giant corporation as compared to an average citizen.
