The applicant must submit evidence to establish custody or responsibility. A court
                  document showing the applicant has custody is sufficient to establish custody and
                  responsibility.
               
               Absent court documents, the applicant may provide other evidence of custody or responsibility,
                  such as a letter from a State Social Services agency placing the NH in the individual's
                  household, a school record indicating that the individual has responsibility for the
                  NH, or a rental agreement listing the NH in the household of the applicant.
