Aretha Franklin's sons are in court this week battling over the control of her estate and assets. Jurors are tasked with determining whether a 2014 document found under sofa cushions in Franklin's home can be accepted as a valid will instead of a 2010 handwritten will found inside of a locked cabinet. Both documents were discovered months after the singer's death. Reid Weisbord, a distinguished professor of law at Rutgers University, joined CBS News to talk about the case.
