A unilateral contract is a legally binding agreement characterized by one party (the offeror) making a promise contingent upon the performance of a specific act by another party (the offeree). Unlike bilateral contracts, where both parties exchange mutual promises, unilateral contracts involve a promise in exchange for an act.
Key Characteristics
- One-sided promise: The offeror offers payment or another benefit once the required action is completed.
- Acceptance through performance: The offeree accepts the contract by fulfilling the required task rather than through a promise.
- Example: A reward offer for a lost pet is a common example of a unilateral contract, where payment is due only upon the return of the pet.
Mechanism: How Unilateral Contracts Work
Formation of Unilateral Contracts
- Offer: The offeror extends a clear and definite offer.
- Performance: The offeree completes the specified task.
- Completion: Upon completion of the task, the offeree can claim the promised reward or benefit.
Legal Enforceability
Unilateral contracts are enforceable under contract law. Courts generally uphold these agreements provided there is:
- A clear offer.
- An act or performance by the offeree fulfilling the terms of the offer.
- Consideration, i.e., the promise of the offeror provides sufficient value.
Types of Unilateral Contracts
Rewards Contracts
These involve offers of rewards for performing specific tasks, such as returning lost property or providing information leading to an arrest.
Insurance Contracts
Certain insurance policies may function as unilateral contracts, where the insurer promises to pay upon the occurrence of a specified event.
Public Offers
Announcements made by companies or individuals to the public, promising compensation for certain actions, also fall under unilateral contracts.
Conditional Contracts
Contracts that become effective only after the occurrence of a specific condition or event.
Special Considerations
Performance Specificity
The required performance must be clear and specific, ensuring the offeree understands exactly what is required to accept the offer.
Termination of Offer
The offeror can revoke the offer before the offeree begins performance. However, once performance begins, many jurisdictions prevent revocation until the task is completed.
Legal Challenges
Disputes may arise over whether the offeree performed the required task precisely as stipulated.
Examples of Unilateral Contracts
- Lost pet reward: A person offers a reward for returning their lost pet.
- Performance bonuses: An employer promises a bonus to employees who exceed certain targets.
- Insurance claims: Payment upon the occurrence of an insured event, like an accident or theft.
Historical Context
Unilateral contracts have a long history in common law. They evolved to facilitate agreements where traditional contract negotiations were impractical, such as public reward offers and certain types of insurance agreements.
Applicability
Unilateral contracts are prevalent in various fields, including employment, insurance, and commercial promotions. They are particularly useful in scenarios involving public offers or performance-based rewards.
