An attempt to contract for an illegal purpose—to commit a murder or other crime or to facilitate an illegal objective (a promissory note for the purchase of illegal drugs)—is unenforceable and does not create a contract. A purported contract that is found to be for an illegal purpose is void and treated as if it never existed.
In Florida, as in all states, a contract must have a lawful purpose to be enforceable. If a contract is formed with the intent to commit a crime, such as murder, or to facilitate an illegal objective, such as the purchase of illegal drugs, it is considered void from the outset. This means that the contract has no legal effect and is treated as if it never existed. Florida law, consistent with general contract principles, will not enforce terms of a contract that require parties to engage in illegal activities or that violate public policy. Therefore, any agreement made with the intention of carrying out illegal activities is not a valid contract under Florida law.
