I am 68 ,I already started my benefits, but was told my ex husband who died and was a doctor did not have more then me. Is it too late to ask them for proof?

Hi. I'm not sure what you would be looking for in the way of proof, but what you can do is contact Social Security to insist on applying for surviving divorced spousal benefits. Social Security would then need to make a formal determination of your eligibility. If your claim is disallowed, your disallowance notice should explain why your claim was disallowed. If you're not satisfied with their decision, you would then have appeal rights.
