I was just granted ssdi and ssi and my father is my representative payee. Does ssi, plus ssi back pay have to be accounted for on what he spends it on for me? ie...like saving receipts for groceries, clothing, and recreation, etc in detail?

Also, does ssdi, plus ssdi back pay have to be accounted for as well? I worked for the ssdi, are there still restrictions on how the money can be spent? Thanks for all your help and god bless. I am 36 y/o male btw...
