'Antenuptial agreement' or 'prenuptial agreement' means an agreement between a man and woman before marriage, but in contemplation and generally in consideration of marriage, by which the property rights and interests of the prospective husband and wife, or both of them, are determined, or where property is secured to either or both of them, to their separate estate, or to their children or other persons. An antenuptial agreement may include provisions that define the respective property rights of the parties during the marriage, or upon the death of either or both of the parties. The agreement may provide for the disposition of marital property upon an annulment of the marriage or a divorce or separation of the parties. A prenuptial agreement is void if at the time it is made either of the parties is a minor.
