Final answer:
A breach of contract lawsuit is the legal action taken when one party wants to enforce a contract and force the other party to perform according to the contract.
Step-by-step explanation:
The legal action you are referring to is called a breach of contract lawsuit. This is when one party believes that the other party has failed to fulfill their obligations as outlined in the contract, and they seek legal recourse to enforce the contract.
In a breach of contract lawsuit, the plaintiff requests specific performance from the court, which means they want the court to order the other party to perform according to the terms of the contract. The plaintiff may also seek monetary damages as compensation for any losses incurred due to the other party's breach.
