I take it you are Eugene.
Because your retirement is higher than was your wife's, there is no benefit to you switching to a survivor benefit (which would pay only the amount your wife was receiving at her death) because you may only collect one benefit at a time and your benefit is the higher of the two.
You will need to notify social security for your wife's death, and you may do that by calling social security at 1-***-***-****.
Additionally, while you are on the phone with social security ask that they process your lump sum
death benefit for your wife. It is $255.00 that will be payable to you.
Other than that, there are no additional social security benefits that you would qualify for based on your wife's passing.
Again, I am sorry for your loss Eugene.
