Title 20 - Employees' Benefits
You may be eligible for benefits if you are related to the insured person as a wife, husband, widow, or widower. To decide your relationship to the insured, we look first to State laws. The State laws that we use are discussed in §404.345. If your relationship cannot be established under State law, you may still be eligible for benefits if your relationship as the insured's wife, husband, widow, or widower is based upon a deemed valid marriage as described in §404.346.
