Which type of contract requires specific performance to fulfill obligations?

The correct answer highlights that specific performance is typically required in contracts involving unique goods or services. Specific performance is a legal remedy used in contract law where a party is ordered to fulfill their part of the agreement rather than merely providing monetary damages for breaching the contract. This remedy is particularly applicable when the subject matter of the contract is unique, as is often the case with certain goods like artwork, real estate, or specialized services.

In situations involving unique goods or services, monetary damages might not adequately compensate the injured party because no substitute can provide the same value or satisfy the specific needs outlined in the contract. For instance, if an artist contracts to create a one-of-a-kind piece of art, that artwork cannot be replaced or valued in the same way as a more common item; thus, the court might order the artist to complete the work as originally agreed.

The other types of contracts mentioned do not necessarily require specific performance. Implied contracts, for instance, are formed through actions or circumstances rather than explicitly stated terms, making it less common for specific performance to be the remedy. Unilateral contracts involve a promise made in exchange for a performance, typically not warranting specific performance. Verbal contracts, while enforceable, can often be more easily resolved with
