What type of contract do Rex and Ben have regarding laundering money?

In the context of laundering money, the contract between Rex and Ben is considered void. A contract is deemed void when it involves illegal activities or is against public policy. Laundering money is a criminal offense, and any agreement that facilitates or engages in such activity is not legally enforceable. Therefore, not only is the contract invalid, but also neither party can seek legal enforcement or protection under the law regarding that contract. This understanding is crucial in real estate law, as it underscores the importance of legality and ethical practices in contractual agreements.
