Which element is not universally required for a contract to be enforceable?

• A. Mutual consent, capacity to contract, consideration, and a lawful object.
• B. Mutual consent and consideration only.
• C. Capacity to contract only.
• D. Written form.

Answer: (D)

The main idea is that some contract elements are universally required for enforceability, while others can vary by situation. A contract typically must have mutual consent (agreement), capacity to contract, a lawful object, and consideration. These are the core pillars that generally make a contract enforceable.

Writing is not always required because oral contracts can be enforceable if these essential elements are present and there is enough evidence of the agreement and its terms. The only reason writing matters is when the law, by the Statute of Frauds or similar rules, requires a written agreement for certain kinds of contracts (for example, real estate transactions, long-term promises, or specific high-value deals). So, while writing becomes necessary for those special cases, it isn’t universally required for every contract.

That’s why written form is the choice that isn’t universally required—the other elements are the universal components that keep a contract enforceable in general.
