An agreement is an expansive concept that includes any arrangement or understanding between two or more parties about their rights and responsibilities with respect to one another. Such informal arrangements often take on the form of “gentlemen’s agreements,” where adherence to the terms of the agreement relies upon the honor of the parties involved rather than exterior means of enforcement.

Handshake. Even today handshakes are a powerful social contract.

A contract is a specific type of agreement that meets certain requirements designed to create legally binding obligations between parties that are enforceable by a court of law.


In order to reach an agreement, parties need only come to a common understanding as to their relative rights and responsibilities, what is often termed a “meeting of the minds.” The requirements for the formation of a contract are more precise and comparatively stricter. A contract must contain the following essential elements:

So long as a contract meets the requirements above, it is enforceable in a court of law, which means that a court can compel a non-compliant party to abide by the terms of the contract. Generally, a contract does not need to be in writing, and in many cases, an oral agreement with all of the elements listed above will constitute a valid and enforceable contract.

Some situations, however, require that a contract be in writing to be enforceable. In the United States, these situations are laid out in each state’s statute of frauds. While the precise list of situations vary from state to state, most statutes of frauds require that contracts for the following be in writing:

An agreement may simply involve one party accepting another party's offer. Since this scenario does not involve consideration, it is not a contract. Other common examples of agreements which are not contracts include gentlemen’s agreements and unlicensed betting pools. The key element to all non-contract agreements is that they are not legally enforceable.

Common examples of contracts are non-disclosure agreements, end-user license agreements (both despite being called “agreements”), employment contracts, and accepted purchase orders. Regardless of how it is named, as long as an agreement contains the required elements of a contract enumerated above, a court may enforce it as such.


The primary benefit of an agreement that does not meet the criteria of a contract is that it is inherently informal. Where the agreeing parties have a longstanding relationship and share a considerable degree of trust, the use of a non-contract agreement can save time and allow for more flexibility in the fulfillment of the agreed-upon obligations. Agreements lacking all the required elements of a contract may also be more viable in situations where the drafting of a contract would prove prohibitively burdensome on the parties involved.

The main advantage of contracts is that they spell out the specific terms that the contracting parties have agreed upon, and in the event of a breach – where one or more parties fail to fulfill their obligations – serve as a guide for a court of law to determine the proper remedy for the injured party or parties. Even where parties have a good relationship and trust one another, the use of a contract provides an extra layer of assurance that the obligations entered into under the contract will be fulfilled as the parties themselves intended. Contracts are generally advisable over less stringent agreements in any official business or commercial matter due to the added protection they provide.
