The Omnibus Budget Reconciliation Act of 1981 (enacted August 13, 1981) provides that
claimants who were entitled to a mother’s or father’s benefit for August 1981 have
a grace period of two years from the date of enactment or the child’s attainment of
age 18 whichever occurs first, before benefits will terminate. Benefits may continue
beyond the grace period if at expiration, the parent has a disabled minor child in
their care (for a child age 18 or over, childhood disability benefits still apply).
