Don't need any song and dance, just a little clarity.
It's not real estate, but I believe when the check was rendered to the third party (FEDX whomever) it was consummated? Or is the moment of conversion to cash (after delivery) the moment?
I'm really only interested in what a Judge would do. Hopefully from someone's experience in front of one.
I think there is remedy available if someone (after receiving consideration) just decides to change their mind.
When I proposed to my wife I was instructed to tell her that "I give thee this diamond in consideration of marriage", specifically to remove any doubt about it being a gift. It's been 30 years, so I can't say if I remember if I get it back should we part ways.
But with so many internet transactions, and communication by e-mail, text, and fax, as well as US mail, and courier services, I suspect most of the fine details of when a sale occurs have been hashed out and clarified.
