Wow.
A lot to consider, here.
Was there ever “a writing,” to evidence the deal?
In many states, any contract that cannot be completed within a year, requires a signed, written agreement, to be enforceable under the “Statute of Frauds.”
Can the “promises” be broken into smaller pieces? The promise of “X amount” “to sign a NLI, today” certainly sounds like something that can be quickly accomplished, avoiding SOF considerations, making oral/verbal contracts enforceable.
How many communications were by text/e-mail, and how many merely verbal conversations? How does Florida deal with texts and e-mails that are in writing and SOF requirements?
