Look. Between you and me, we say something to each other, we hold each other to it. We ask a third party, like a judge, to adjudicate - they're going to want to see some evidence. This is why in almost every state, real estate agreements must be in writing: so that a judge can review the contract and the attorneys can argue about the wording.
The purpose of a contract isn't to bind us to one another - we can shake hands on the matter; it's so that third parties such as lenders and escrow agents and judges can determine whether we have fulfilled the terms of our agreements.
