20 C.F.R. § 404.333 Wife's and husband's benefit amounts.
Title 20 - Employees' Benefits
Your wife's or husband's monthly benefit is equal to one-half the insured person's primary insurance amount. If you are entitled as a divorced wife or as a divorced husband before the insured person becomes entitled, we will compute the primary insurance amount as if he or she became entitled to old-age benefits in the first month you are entitled as a divorced wife or as a divorced husband. The amount of your monthly benefit may change as explained in §404.304. [51 FR 11912, Apr. 8, 1986]
