A prenuptial or partition agreement cannot provide terms regarding children born during the marriage. Any decision about children will be made based on their best interest at the time that the decision is made. Other than that, there are no limitations of a prenuptial agreement that you can make about your property. The standard prenup available on this site provides that each spouse keeps all in his or her name, all that he or she has before marriage, and all that he or she earns or acquires during the marriage.
