The Royal Forester Will Dai pay the fine before, or if, he goes? But he will pocket any incoming transfer fees this week though. Leaving Couhig to pay the fine, IIF or when the deal is done.
I'd assume the SPA ( Sale & Purchase Agreement) would include a whole bunch of contingencies based on liabilities, etc - so the end sale price & payment schedule would be based on agreed criteria being met.
Otherwise things can get very legal very quickly...
