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 a 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.
