completely . . .
You want to make an argument that the contract is enforceable due to the course of performance, but one party had no duty to actually perform any actions under the contract and there is not evidence of actual performance under the terms of the contract by that party, so that party will have a very hard time making that argument.
This is not complex. Point to the actual actions that are performance or find another argument.
Oh man, I get it, you are completely missing the point.
Trump is going to say, of course the contract was enforceable, EC is going to agree, and then Stormy is going to say, what exactly? There was no contract because he didn't sign it, even though she got paid, and he never acted inconsistently with the agreement? That is silly.
Further, the contract says he will release the claims. Did he act inconsistently with that by, say, suing her (before she breached the contract) Of course not.
Did he contact her family after promising he would not? Of course not.
Are you really trying to convince people that where a contract says that he will refrain from doing something that performance in compliance with that undertaking is not course of performance?
Spectacularly absurd. Please study the various cases I have cited (particularly the one from Ohio).
Any questions, i am sure you will let me know...
