Which breach of contract remedy requires a seller to complete a contract of sale?

The remedy that requires a seller to complete a contract of sale is specific performance. This legal remedy is often invoked when monetary damages are inadequate to resolve the breach. In real estate transactions, properties are considered unique, and buyers may be compelled to complete the sale in instances where they have a valid contract with agreed-upon terms.

Specific performance orders the breaching party, in this case, the seller, to fulfill their obligations as outlined in the contract rather than just compensating the buyer with money. This is particularly significant in real estate, where the exact property identified in the contract may be difficult or impossible to replace, thereby justifying the court's interference to ensure the contract is completed.

In contrast, damages typically involve financial compensation for losses incurred due to the breach, while rescission allows for the cancellation of the contract, and liquidated damages are predetermined amounts specified in the contract that one party agrees to pay to the other in the event of a breach. None of these remedies would compel the seller to fulfill their contractual obligations to complete the sale as specific performance does.
