From the article: Should You Get a Post-Nuptial Agreement?
Most modern couples come into marriage with investments, cash, and property that they've bought and inherited in the years before they met. Deciding how to deal with your money and assets -- whether to maintain separate or joint accounts, share deeds to homes, etc. -- is one of the first challenges of a new marriage. Prenuptial agreements are one solution. Some people think these legal documents are a must because they explain how to deal with personal finances. Others think they are unromantic and only necessary if you plan on divorcing. What do you think?
