What is the legal remedy that compels a breaching party to fulfill their contractual obligations?

The legal remedy that compels a breaching party to fulfill their contractual obligations is specific performance. This remedy is often sought in situations where monetary damages are insufficient to remedy the harm caused by the breach. Specific performance is particularly applicable in contracts involving unique items or properties, such as real estate, where the subject matter cannot easily be replicated or replaced.

In this context, a court would order the breaching party to execute their part of the agreement, convincing them to act according to the terms initially agreed upon. This distinguishes specific performance from other remedies such as damages, which involve a monetary compensation without requiring actual performance of the contract itself.
