In order for a contract to be legal it must be presented in some way required by law such as orally in writing or implied by the conduct of the parties?

For a contract to be legally binding, it must adhere to specific requirements set by law, which can include being expressed orally, in writing, or implied through the actions of the parties involved. The essential elements of a contract, such as offer, acceptance, and consideration, must be present regardless of the form it takes. Certain types of contracts, like those involving real estate or significant sums of money, may be required to be in writing to be enforceable. Ultimately, the clarity and mutual consent of the parties are crucial for the contract's legality.
