Our handicapped sister is going to live with her (our sister) representative payee, she is going to be charged $450.00 a month and her check is about $600.00 a month. The representative payee lives with a boyfriend who doesn't work and receives a check for his deceased wifes pension, the payee is also on disability and does not work. Between the both of them (payee and boyfriend) they receive quite a bit of money. Can they charge this much for rent and is it possible for my sister to live off the little bit left over? She suffers from cerebal palsy and needs help with all basic needs.
