A void contract is a contract that has no legal effect, from the outset or ab initio. It is not enforceable by law, and it does not create any legal obligations or rights between the parties involved. This is because the subject matter of the contract may be illegal, against public policy or contrary to law, or the parties may lack the legal capacity to enter into the contract. In other words, a void contract is not a valid contract, and it cannot be enforced by any court of law.
