Contract types

The two primary categories of contracts are "unilateral" and "bilateral." In a unilateral contract only one party promises something. For instance, if a car dealer tells a customer, "I will give you that car if you give me $15,000," he has made an offer for a unilateral contract—the contract will only be created if the customer accepts the offer by paying the $15,000. If the dealer says, "I will promise to give you the car if you promise to pay me $15,000," a bilateral contract has been proposed because both parties must make a promise. The concept of unilateral contracts is important because it has been used by courts to hold a party liable for a promise even when consideration was not given by the other party. For instance, an employer may be liable for providing pension benefits that it promised to an employee, even if the worker gave no promise and did nothing in return.

Contracts may also be classified as "express" or "implied." Express contracts are those in which both parties have explicitly stated the terms of their bargain, either orally or in writing, at the time that the contract was created. In contrast, implied contracts result from surrounding facts and circumstances that suggest an agreement. For instance, when a person takes a car to a repair shop he expects the shop to exercise reasonable care and good faith in fixing the car and charging for repairs. Likewise, the shop expects the customer to pay for its services. Although no formal agreement is created, an implied contract exists.

In addition to express and implied contracts are "quasi-contracts," which arise from unique circumstances. Quasi-contracts are obligations imposed by law to avoid injustice. For instance, suppose that a man hires a woman to paint his house. By accident, she paints the wrong house. The owner of the house knows that she is painting it by mistake but, happy to have a free paint job, says nothing. The painter would likely be able to collect something from the homeowner because he knowingly was "unjustly enriched" at her expense. Had she painted his house while he was on vacation, he would be under no obligation to her.

Contracts may also be categorized as valid, unenforceable, voidable, and void. Valid contracts are simply those that meet all legal requirements. Unenforceable contracts are those that meet the basic requirements but fail to fulfill some other law. For instance, if a state has special requirements for contracts related to lending money, failure to comply could make the contract unenforceable. Voidable contracts occur when one or both parties have a legal right to cancel their obligations. A contract entered into under duress, for example, would be voidable at the request of the injured party. Void contracts are those that fail to meet basic criteria, and are therefore not contracts at all. An illegal contract, for example, is void.

A separate type of contract, and one which overtly exemplifies the trend away from strict interpretation and toward fairness, is created by promissory estoppel. Under the theory of promissory estoppel, a party can rely on a promise made by another party despite the nonexistence of a formal, or even implied, contract. Promissory estoppel can be evoked if allowing a promisor to claim freedom from liability because of a lack of consideration (or some other contractual element) would result in injustice. Suppose that a business owner promised an employee that he would eventually give her the business if she worked there until he (the owner) retired. Then, after 20 years of faithful service by the employee, the owner decides to give the business to his son-in-law. The owner could be "estopped" from claiming in court that a true contract did not exist, because the worker relied on the owner's promise.
