Natural person

In jurisprudence, a natural person is a human being perceptible through the senses and subject to physical laws, as opposed to a legal person, i.e., an organization that the law treats for some purposes as if it were a person distinct from its members or owners.

For example, such legal provisions as Amendment XIX to the US Constitution, which guarantees a woman's right to vote, apply to natural persons only. In many cases fundamental human rights are implicitly granted only to natural persons; for example a corporation cannot hold public office, but it can file a lawsuit.
