How to Tell Whether a Family Member May Qualify for Auxiliary or DAC Benefits

When Social Security disability benefits enter the picture, families often realize there may be more than one person affected. A worker’s disability can sometimes open the door to benefits for a spouse, a child, or an adult son or daughter with a disability that began years earlier. The hard part is figuring out which program fits which family member, and whether the facts line up with Social Security’s eligibility rules.

That confusion is common. The Social Security Administration says family benefits may be available to certain spouses, ex-spouses, children, and in some situations grandchildren of a person entitled to retirement or disability benefits, and that children of a retired, disabled, or deceased worker may also qualify in specific circumstances (SSA family benefits; SSA eligibility rules; SSA Benefits for Children PDF). For families trying to sort out whether a loved one may qualify, the details can feel more technical than expected.

In broad terms, auxiliary benefits commonly involve:

DAC benefits are a little different. They are often called Childhood Disability Benefits (CDB) by Social Security. These benefits may be available to an adult child age 18 or older who is disabled, became disabled before age 22, is unmarried in most situations, and meets the other rules for child’s insurance benefits on a parent’s Social Security record (SSA Handbook § 518; SSA POMS DI 10115.001).

Step 1: Identify The Worker Whose Record The Claim Would Be Based On

The first question is usually simple: whose Social Security earnings record is involved?

Auxiliary and DAC claims are not built around the family member’s own work history. They are built around the earnings record of a person who is:
