Okay kiddo, so a natural person in French law is just a fancy way of saying a human being or a person who is born and alive. It's different from a company or a corporation, which is made up of a bunch of people working together.
In French law, natural persons have certain rights and responsibilities that companies don't have. For example, people have the right to vote, to get married, and to own property. They also have responsibilities like paying taxes and following laws.
Overall, a natural person is just a regular person like you and me, and they are very important in French law because they make up the majority of the population and have unique needs and freedoms that need to be protected.
