You can get your deposit back--and possibly sue for other damages--IF the club does not honor its obligations, or you get a firm indication that they will not honor them. (Of course, if they won't pay the money back voluntarily, you would have to sue.)However, rumors of a sale do not entitle you to get your money back yet--after all, even if those rumors are true, 1) the sale may or may not actually occur or go through; 2) if the sale happens, it may not occur until after the wedding; and 3) even if the place is sold, that doesn't mean the new owner/buyer won't honor the country club's contracts. So until it is clear there will be nonperformance, you don't have grounds to get the deposit back.
