I have been married three times. Two of my marriages were been more than 10 years each. I’m 62 years old, I’m not collecting any benefits at this time. My question is if one of my ex spouses passes away would I be able to collect survivor benefits on that one and if the other dies later and there is a larger amount to collect would I be able to switch to that one?
Yes, assuming that you meet all of the requirements for entitlement (https://www.ssa.gov/OP_Home/handbook/handbook.04/handbook-0403.html).
