A bilateral contract is a type of agreement in which both parties make reciprocal promises to each other. Each party is both a promisor (someone making a promise) and a promisee (someone to whom a promise is made). This mutual exchange of promises differentiates bilateral contracts from other types, such as unilateral contracts.
Definition
A bilateral contract incorporates a commitment by both parties to perform certain actions or refrain from performing certain actions. For instance, in a sales contract, one party promises to deliver goods or services, while the other party promises to pay for those goods or services.
Types of Bilateral Contracts
- Sales Contracts: Agreements between buyer and seller for the exchange of goods, services, or property.
- Employment Contracts: Agreements where an employer promises to pay and an employee promises to work for a specified period.
- Service Contracts: Agreements between a service provider and a client, outlining the nature of the services to be performed.
- Lease Agreements: Contracts where the lessor promises to allow the lessee to use a property, and the lessee promises to pay rent.
Special Considerations
Formation Requirements
For a bilateral contract to be binding and enforceable:
- Offer and Acceptance: There must be a clear offer by one party and acceptance by the other.
- Consideration: Each party must receive something of value; it could be money, services, goods, or a promise to perform/refrain from an action.
- Capacity and Legality: The parties entering into the contract must have the legal capacity to do so, and the contract’s subject matter must be legal.
Performance and Breach
Performance in a bilateral contract requires both parties to fulfill their promises. Failure to do so results in a breach of contract, giving the non-breaching party the right to seek legal remedies such as damages, specific performance, or contract rescission.
Historical Context
The concept of bilateral contracts has evolved from ancient times where agreements were often made verbally and sealed with handshakes, to more complex written contracts seen today. The development of contract law, particularly in English common law and later in American jurisprudence, has shaped the modern understanding and enforcement of bilateral contracts.
Comparisons
Bilateral vs. Unilateral Contracts:
- Bilateral Contract: Both parties make mutually binding promises (e.g., a sales agreement).

Related Terms
- Unilateral Contract: A contract where one party makes a promise in exchange for the other party’s performance.
- Consideration: Something of value exchanged by the parties in a contract.
- Offer and Acceptance: The process by which a contract is formed, involving one party making an offer and the other party accepting it.
- Legal Capacity: The ability of the parties to enter into a contract, typically requiring them to be of legal age and sound mind.
- Specific Performance: A legal remedy where the court orders the breaching party to perform their contractual obligations.
FAQs
Q1: What happens if one party does not perform their promise in a bilateral contract?

- Answer: Consideration in bilateral contracts involves the exchange of promises, where each party agrees to give something of value to the other.
Q4: Are bilateral contracts legally enforceable?
