What constitutes an "agreement" in contract law?

In contract law, an "agreement" is fundamentally defined as a meeting of two or more minds concerning the terms of a contract. This principle emphasizes the necessity of mutual assent, where parties involved reach a common understanding about the essential terms and conditions of the agreement. This meeting of the minds signifies that both parties are on the same page and have a shared intention to enter into a binding relationship, leading to enforceable obligations.

While other options mention forms of agreements such as written contracts or verbal agreements, these are just manifestations of the larger concept of an agreement. The presence of witnesses or notarization can help provide evidence of an agreement, but they are not prerequisites for an agreement to exist in the legal sense. Similarly, a mutual understanding without obligations does not fulfill the requirements of a contract, as it lacks the essential elements needed for enforceability. Thus, the essence of an agreement lies in the mutual assent regarding the terms, making "a meeting of two or more minds regarding terms" the correct understanding.
