A contract violation occurs when one party fails to fulfill their obligations as outlined in a legal agreement. This can include not delivering goods or services, missing deadlines, or not adhering to specific terms. Such violations can lead to disputes and may require legal action to resolve. When a contract is violated, the affected party may seek remedies, which can include monetary compensation or specific performance, where the violator is required to fulfill their original obligations. Understanding the terms of the contract is crucial for both parties to avoid misunderstandings and potential violations.
