gentleman's pact
A legally non-binding arrangement that is guaranteed only by a verbal or mutually understood agreement by the parties involved. Though my father left me his entire estate in his will, I made a gentleman's pact with my brother to share the wealth equally between us. Fellows, you do realize that I have no obligation to honor a gentleman's pact, right? I know you trust him, but I'd still get him to sign something. A gentleman's pact won't get you anywhere in court.
