All valid contracts have to follow some basic rules. At its most basic a contract is formed when one party makes an offer of an exchange of value to another party, who accepts the offer. The legal elements of a contract include mutuality of obligation, which is comprised of offer and acceptance, definite terms, and consideration. These elements must all be present in order for a contract to be enforceable. In addition, the contract must have been made for a legal purpose and all parties involved must be competent. The negation of one or both of the latter two requirements – legal purpose and competence – can also render a contract unenforceable but are not usually considered as part of the basic elements of a contract.

  1. Mutuality of Obligation

Mutuality of obligation, or meeting of the minds, means that the parties to a potential contract must agree on the specifics of the bargain. Mutuality of obligation is demonstrated by an offer by one party and acceptance of that offer by another.

  1. Offer

An offer is defined as a manifestation of willingness to enter a bargain. This manifestation must be made in a way that justifies another person in understanding that if he or she accepts, the bargain is concluded. Simply put, when someone proposes an exchange to another person, that is an offer.

  1. Acceptance

Acceptance is a manifestation of assent to the terms of the offer and can be made in a number of ways. If the offer specifies a manner of acceptance, the person being offered the bargain (the offeree) must accept in that fashion. Sometimes, the offer can be accepted by a return promise or by actual performance of the promised act. Courts now generally find acceptance can be by any reasonable means under the circumstances unless the language of the offer indicates otherwise.

An offer that allows the offeree to accept only by a promise is called a bilateral contract. A bilateral contract is considered formed when the offeree promises to perform some obligation in the future. If the offeree never performs the obligation, then there has been a breach of contract because the promise to perform was acceptance of the offer.

An offer that requires the offeree to accept by performance of the promise is called a unilateral contract. If the offeree never performs, there is no breach of contract because there was no contract. The contract was never accepted as indicated in the offer.

Generally, silence cannot constitute acceptance. However, if the parties have prior dealings in which silence was the method of acceptance or if the offeror has indicated that acceptance can be made by silence, then silence will suffice.

  1. Definite terms

A contract is only binding if a court can look at the bargain and determine the parties’ obligations. The terms of the contract must be reasonably certain. The theory behind this is that the parties could not have formed a contract without agreeing upon the material terms of that contract. This element is sometimes considered as part of the offer.

  1. Consideration

Consideration is what the parties exchange that is of value. A promise must generally be supported by consideration in order to be enforceable. Consideration can be many things. It can be a benefit, profit, or, alternatively, some loss or responsibility that is incurred or assumed. It does not have to be money. Courts will not usually judge the adequacy of consideration. However, they will ensure that what was exchanged (or promised to be exchanged) had some value. In addition, the exchange at issue must have been bargained for by the parties.

So, there are many guides to contract writing, but there are some key elements that all contracts require, including:

  • Intent to make a contract;
  • A lawful subject matter;
  • An offer made by one party;
  • Acceptance of the offer by the other party;
  • An exchange of something of value;
  • A written agreement, in some circumstances.
