The amount of a spouse’s benefit is as follows:
If only one spouse is entitled, he or she receives one-half the PIA of the NH subject
to the normal rules on adjustment for the maximum and the rounding of benefits, and
subject to reduction for age.
If more than one spouse is entitled, each qualifies for an amount equal to one-half
of the PIA, subject to the rules on adjustment for the maximum and rounding of benefits,
and subject to reduction for age.
When a legal spouse and deemed or putative spouse are simultaneously entitled, the
legal spouse’s benefit is not subject to adjustment for the family maximum for the
first and all subsequent months of entitlement. This is effective for benefits payable
for months after December 1990.
