You must establish relationship, custody, and responsibility in every case when the
            person who signs (either electronically through SSNAP or on a paper SS-5) the application
            is not the person to whom we will issue the card. Once it is clear that no one higher
            on the priority list exists and you have established relationship, custody, and responsibility,
            consider the individual a proper applicant.
         
         When the applicant is not a proper applicant, or cannot establish relationship and
            custody, return the application and evidence and provide the individual with a written
            notice per Providing Written Notice and Second Review When SSN or Card Cannot Be Issued,
            RM 10215.110.
