Difference Between Unilateral and Bilateral Contract

A contract is a deliberate and voluntary agreement between two competent persons that can be enforced by the law and can either be written or spoken. They can be made in regards to a tenancy, lease or sale of property and employment. 

A contract is legally binding where;

  • An offer is made, accepted and is mutual
  • There is a consideration. This means that there has to be something of value exchanged between the parties. 
  • Both partied are competent to make a contract
  • The contract must be legal

Unilateral and bilateral contracts are types of contracts made on daily basis in professional and personal matters. 

 

What is Unilateral Contract?

A unilateral contract is a contract done by one person or one party, hence allows one person to make an agreement. The person who makes the contract is hence held responsible for ensuring the terms and conditions of the contract. In this type of contract, it is important to state a specific period under which the contract is valid. 

Examples of a unilateral contract are a case scenario whereby a person promises a reward to a person who finds a lost item. Insurance companies also involve unilateral contracts, where the insurance company agrees to pay the insured specific amounts of money in case a certain incident occurs. 

 

What is Bilateral Contract?

A bilateral contract is a contract between two or more parties. Normally, one party makes a promise to another party to do something in exchange for the other party’s promise to also do something.

This is the most common type of contract in the day to day activities. One party must actually perform, as opposed to promising to perform, such as the actual making of a payment, or the act of offering a service.

For example, ordering a meal at a restaurant, receiving medical care, making a purchase, real estate contracts, electricity services and, gas services, just to name a few. 

 

Similarities between Unilateral and Bilateral Contracts

  • Both involve an offer that must be mutually accepted by the parties involved
  • Both contracts can be breached. This means that the contract can be broken due to the failure to fulfill any terms in the contract.
  • They can either be written or oral
  • Both are enforceable in a court of law

 

Differences between Unilateral and Bilateral Agreements

  1. Parties involved in Unilateral and Bilateral agreements

While unilateral contracts involve one person or party, bilateral contracts involve one or more parties. 

  1. Offers of rewards for Unilateral and Bilateral agreements

In a unilateral contract, any offer of a reward is made and effected only be the promisor, who is legally bound to the promise he made. The promisee in this case only accepts the offer. On the other hand, in a bilateral contract, offers and rewards do not apply since both parties are required to make promises. 

  1. Time-frame

In a unilateral contract, the promisor has to specify the duration of the offer. In bilateral contracts, however, both parties have to agree on a timeframe in which the agreed service or product shall be delivered, failure to which can lead to a breach in the contract.
