You've heard about a pre-nup. Why not try a post-nup? Hillary Wicai reports on a trend that's helping many couples live happily ever after. TEXT OF STORY KAI RYSSDAL: It's summer as you know, so rabbis, priests, ministers and justices of the peace are busy marrying couples off. The goal of course is happily ever after. But so often money makes it more like "frustrated ever after." Cash almost always tops of the list of what couples argue about, but there is a new way for them get back to happy again. From the Marketplace Work and Family Desk, Hillary Wicai reports. HILLARY WICAI: Thirty years ago, a guy we'll call Bill wed his true love, a woman we'll call Sally. (They don't want to use their real names.) But back then they had dreams of happy children and meaningful careers that would help make the world a better place.
