I wouldn't expect most "handshake deals" with a friend/spouse to require that level of formality - unless money is changing hands.
Long story short, a quick text with "About to cash the vacation check you wrote" would have saved us a fight. OTOH, coming up on 10 years together, so I think it worked out OK.
I think that the protocol as described makes a lot of sense, because paperwork. (Although I think Clerky was supposed to be trying to help out with that?)
You bastard! She forgot and you cashed it anyway! haha.
