The issue here is the nature of contracts. A written dcoument signed by all parties is not (necessarily) a contract. It is evidence of a contract. Any agreement of exchange of goods and services may be a contract, whether it's an email, a phone call, a handshake, or almost anything else. A written document, video, or audio recording merely serves as evidence of the contract.
