I have been married to my husband for more than 20 years. We were both in our early twenties when we were married according to customary rites as well as civilly out of community of property. Since then my husband has built up a few successful businesses and a few years ago we created our own post-nuptial agreement to confirm that we see ourselves as married in community of property. Unfortunately, we have fallen on troubled times and wish to get divorced. My husband says we are still married out of community of property as the agreement we signed late is invalid. Is this true?
