I need more information about the benefits that widows and widowers will get, or first tell me about the benefits that are available to them as they get older.
ok. For your widow, the benefit could start as soon as she turns 60, getting reduced benefits, or full benefits at the full retirement age. If your widow is disabled she could start getting the benefits at age 50 if her disability started before your death or up to seven years after.
