Prenuptial and postnuptial agreements provide individuals and married couples a way of protecting assets and defining ownership rights outside of the confines of community property laws. A prenuptial agreement is prepared and signed by both parties prior to the marriage. It takes effect upon the marriage. A post-nuptial agreement is drafted and signed by both parties during the marriage. It is generally an agreement that is not entered into in anticipation of divorce, but rather an agreement through which married persons want to define their rights in certain property. Rachel Castrejon has a wealth of experience in drafting both prenuptial and post-nuptial agreements.
