In Ohio, what must parties to a contract do for it to be enforceable?

For a contract to be enforceable in Ohio, the key elements required are mutual consent between the parties and valid consideration. Mutual consent means that both parties agree to the terms of the contract and show their intent to be bound by it, typically through an offer and acceptance. Valid consideration refers to something of value that is exchanged between the parties; it can be money, services, goods, or a promise to do something or refrain from doing something.

Without mutual consent, there is no agreement, and without valid consideration, there is no legal basis for enforcing the contract. These elements ensure that contracts are not merely informal agreements but rather legally binding commitments that can be upheld in a court of law.

The other options mentioned do not capture these essential requirements. Signing the contract alone does not guarantee enforceability if there is a lack of mutual consent or consideration. Filing with the state or notarization may be necessary for specific types of contracts, but they are not blanket requirements for enforceability in all situations.
