What constitutes a breach of contract?

A breach of contract occurs when one party fails to fulfill their obligations as specified in the agreement. In this context, the failure of one party to meet the terms outlined in the contract signifies that they are not adhering to the agreed-upon conditions. This non-compliance can take many forms, such as not delivering goods or services by the specified timeline, failing to make payments, or not performing the required duties or actions.

When discussing the other options, it is clear they do not represent a breach of contract. For instance, the completion of all agreed terms indicates that both parties have upheld their contractual commitments, which is the opposite of a breach. The creation of an interest in real property refers to establishing rights or ownership in property, not an action related to contract fulfillment. Lastly, agreement on an amendment implies that parties are actively modifying their prior agreement, which does not denote breach but rather cooperation and negotiation.
