However, if either refuses to complete the bargain (either the prostitute after being paid, or the payor after receiving the service) then the court will not assist the disappointed party. Similarly under English law, a gambling contract is valid, but unenforceable (gambling contracts are sometimes said to be "binding in honour only").
