An example of a transaction which is an unenforceable contract is a contract for prostitution under English law. Prostitution is not actually a crime under English law, but both soliciting a prostitute and living off the earnings of a prostitute are criminal offences.[1] Yet so long as the contract is fully performed, it remains valid. However, if either refuses to complete the bargain (either the prostitute after being paid or the payer after receiving the services), the court will not assist the disappointed party.[citation needed]
