Mr. Green's doctor submitted a Form SSA-787 (Physician’s/Medical Officer’s Statement
                        of Patient’s Capability to Manage Benefits) describing Mr. Green's condition and stating
                        that Mr. Green is incapable.
                     
                     Mr. Green's sibling, who is also their custodian, files a payee application. Mr. Green's
                        sibling states that Mr. Green is unable to handle their own benefits because they
                        do not know the value of money and frequently gives it away to strangers.
                     
                     At the interview, Mr. Green does not seem to understand your questions and answers
                        them incoherently.
                     
                     In this case, lay evidence of capability would be your observations of Mr. Green's
                        incoherent speech and his sibling's statement that Mr. Green is unable to handle their
                        own benefits. Both the medical and lay evidence seem to agree that Mr. Green needs
                        a payee.
