ssd before death, affect on survivor benefits

Please consult the SSA directly for verification, but I have not seen any indication that previously receiving disability benefits would affect survivor benefits.

The biggest potential impact would be your decision to take survivor benefits at age 60, rather than waiting for your full retirement age. Waiting until age 62, 65, or even later will increase your monthly payment.

These are examples of the benefits that survivors may receive:

• Widow or widower, full retirement age or older -- 100 percent of the deceased worker's benefit amount;
• Widow or widower, age 60 -- full retirement age -- 71.5 to 99 percent of the deceased worker's basic amount;
• Disabled widow or widower aged 50 through 59 -- 71½ percent;
• Widow or widower, any age, caring for a child under age 16 -- 75 percent.
• A child under age 18 (19 if still in elementary or secondary school) or disabled -- 75 percent.

Percentages for a surviving divorced widow or widower would be the same as above.
