A bilateral promise is a contract wherein each party agrees to perform in specific manners to complete a deal. It's the type of contract that's used the most frequently. As an example, when one person offers to sell something and another agrees to buy it for a specific price, this forms a bilateral agreement. Each party agrees to do something. The seller agrees to transfer ownership, and the buyer agrees to pay for it. Each party is legally bound to reciprocate as agreed, and this type of contract involves two or more parties.

Mutual Consideration

Every business contract with one party promising to do something for the other party is a contract that's bilateral. The term bilateral means the involvement is equal on each side. In a bilateral business contract, both sides are equally required to perform some type of action. Each party in a bilateral business contract has certain rights and assigned obligations. This means both sides give and receive consideration.

Bilateral contracts require the party being offered something to acknowledge acceptance to the party making the offer.

  • The party making the offer and the party accepting the offer are mutually bound under a bilateral business contract.
  • The parties in bilateral contracts may also be referred to as promisors and promisees, though this depends on the type of contract in question.
  • The moment the bilateral promises are exchanged, the bilateral business contract becomes legally binding upon each involved party.
  • The presumption is that business contracts are bilateral in nature unless the intention is obviously otherwise.

To simplify the way bilateral business contracts are defined, bilateral contracts are sometimes called contracts that involve only exchanged promises. A contract that calls for an immediate exchange of consideration doesn't qualify as a bilateral contract.

The Role of Negotiation in Bilateral Contracts

Negotiation isn't a required step in establishing a bilateral contract. It is, however, a commonly used technique. The way a bilateral contract differs from a unilateral contract is that there is a mutual sharing of responsibility in a bilateral one. It's the exchange of mutual promises or reciprocation that establishes a bilateral contract as legally binding in nature. At its core, the offer is expressed as a promise, and to accept it, the second party delivers a counter-promise.

Unilateral Contracts

A bilateral contract differs from a unilateral contract. Only one party is required to fulfill a promise in a unilateral contract. Some issues can arise that complicate both unilateral and bilateral agreements, including the absence or presence of verbal agreements, written agreements, and time that's passed. With a unilateral offer, one party presents an offer and no one is under any obligation to accept the offer.

Unilateral offers are usually presented to numerous people. As an example, if a store issues a discount coupon, the only party obligated by the offer is the store. If a customer comes in to use the coupon, the store is legally bound to provide the discount if the customer purchases the item in question. Anyone who sees the ad and visits the store has the right to use the offered coupon.

Bilateral or Unilateral?

The party on one side of a contract extends an offer of something that has value, either goods, services, or an oath to act or not act in a certain manner. This inspires the second party to enter into a contract. The exchange of consideration between the parties is what the courts look at to determine if the contract is bilateral or unilateral. Each party in a bilateral agreement must offer something that has value as a form of consideration at the time the promises are made.

Unilateral Contracts Can Become Bilateral

Unilateral contracts are only binding upon the party that makes the offer. This party is also referred to as the promisor. The unbound party, the promisee, isn't under any obligation unless he or she accepts the contract and offers the requested obligation to the promisor. Court rulings have held that the moment the promisee begin to engage in the unilateral offer, it turns into a bilateral offer. At that time, both parties become bound to the agreed upon performance.
