The resources of a qualified individual are deemed to include the resources of an
            essential person. Essential person resources that are excluded from deeming to the
            qualified individual are described in SI 01330.420.
         
         If the essential person's resources cause the qualified individual to be ineligible,
            then the individual ceases to have that essential person effective the same month.
         
         The essential person status cannot be regained after it is lost. Essential person
            deeming and the essential person increment do not apply once the essential person
            status ceases.
         
         If essential person status is lost, and the essential person is an ineligible spouse
            of a qualified individual, or an ineligible parent (or spouse of a parent) of a qualified
            individual who is a child under age 18 living in the same household, spouse-to-spouse
            or parent-to-child deeming, as appropriate, applies.
