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 Louisiana, as in all states, a contract that is created for an illegal purpose is considered void and unenforceable. This means that if a contract's objective is to commit a crime, such as murder, or to facilitate an illegal activity, such as the purchase of illegal drugs, the law treats the contract as if it never existed. Louisiana law adheres to the basic principle that a contract must have a lawful object, and when the purpose of the agreement violates the law or public policy, it cannot be upheld by the legal system. Therefore, any agreement to perform an illegal act is not recognized as a valid contract, and the courts will not assist in enforcing its terms.
