What does the statute of frauds require for certain contracts to be enforceable at law?

The statute of frauds is a legal concept that mandates that certain types of contracts must be in writing and signed in order to be enforceable in a court of law. This requirement primarily applies to contracts that involve significant obligations, such as agreements for the sale of real estate, leases lasting more than one year, and contracts that cannot be performed within one year.

The necessity for a written and signed document helps to prevent fraud and misunderstandings by ensuring that there is clear evidence of the terms of the agreement and the parties' intentions. Written contracts also provide a tangible record that can be referred to in case of disputes. The signature of the parties involved serves as a confirmation of their agreement to the terms outlined, adding an extra layer of accountability.

Overall, the enforceability of these contracts hinges on the presence of a written and signed document, making this option the correct choice. Other options do not align with the requirements set forth by the statute of frauds, as verbal agreements, implied conduct, or the requirement for witness signatures do not conform to these legal standards for enforceability.
