Section 414 of P.L. 108-203, enacted on March 2, 2004, created an additional situation
                  in which the 9-month duration of marriage requirement is deemed to be met, for surviving spouses
                     only. Effective for applications filed in or after March 2004, the 9-month requirement
                  is deemed to be met if SSA determines that the surviving spouse claimant and the deceased
                  NH would have been married for at least 9 months, except that it was unlawful for
                  the number holder (NH) (under the law of the State where they were domiciled) to divorce
                  the prior spouse by reason of the prior spouse’s institutionalization because of mental
                  incompetence or a similar incapacity. The prior spouse must have remained institutionalized
                  until the time of their death, and the NH must have married the surviving spouse claimant
                  within 60 days after the prior spouse’s death.
               
               
                  
                     NOTE: The new duration-of-marriage exception applies only to situations where the NH’s prior
                           spouse was institutionalized, not to situations where the surviving spouse claimant had a prior institutionalized spouse. The new exception does not apply in determining
                        the duration of a surviving stepchild’s relationship to the NH.
