A lawyer can help you determine what needs to be in your written contract to make it a legally binding and enforceable in a Florida court.

Consideration is the agreement to give up something in exchange for receiving something. It is an essential element for forming a legally binding contract. In Florida, a contract is established through a simple but vital process: offer, acceptance, and exchange of value (consideration). Is your business entering into a contract? It's important to know what is involved. Any agreement to perform an illegal act is not enforceable under Florida law. This ensures that contracts adhere to legal and ethical standards.
