Which of the following contracts can be enforced without a written agreement?

The correct answer highlights that a one-year residential lease can be enforceable even without a written agreement under certain circumstances. In many jurisdictions, leases for less than one year can be made orally and are legally binding. While a written contract is generally required for leases that extend beyond one year to comply with the Statute of Frauds, a verbal agreement can suffice for shorter durations.

Understanding the context of this question hinges on the conditions established by the Statute of Frauds, which aims to prevent fraudulent claims by requiring certain contracts to be in writing. Although verbal agreements are typically less enforceable and can lead to disputes over terms, they can still carry legal weight depending on the situation and local laws, particularly for transient agreements or ones requiring shorter commitments.

In contrast, other options involve commitments that legally require written documentation to enforce, such as employment contracts longer than one year or contracts for the sale of goods exceeding $500, as these are explicitly covered under the Statute of Frauds.
