Ruth Gretz of RTD Financial in Westport, Conn., and Peter Lang of HighTower Westchester (NY) discussed properly maintaining beneficiary designations on this week's Collective Wisdom podcast, noting that it's a small, forgettable task that has big consequences when not kept current after life events and other changes. They discussed the gamut of documents and situations where a small mistake -- not updating a form -- can have enormous consequences that can effect families for generations.
