Well, one important thing is to know that there are limits on how much your survivors may earn while they receive the benefits.
Tell me about what would happen if my surviving divorced wife remarries after my death.
If she remarries before turning 60 then she won't be able to get the benefits while she is still married.
And what if she qualifies but the amount she could get from her new husband's Social Security benefits are more than what she would receive from mine?
