Our son lived in a garage apartment we built on our property for him. I paid for Jeb’s rent, utilities, groceries and clothing from his ssi/ssdi account. I gave him a credit card with his name -it was my account, but I never used it. That way he could buy his groceries himself and I could pay the bill directly from the ssi/ssdi account. He also had a SNAP card for groceries. ($110. a month)
I put $50 in his debit card account each month for him to spend anyway he wanted.
Because our area isn’t an expensive area to live, we charged him $400 for rent (Social Security wants it to be market rate rent) After giving him $50, that left him with $305. for utilities, groceries and clothing. I would keep an eye on his charges during the month and let him know if he was getting close to his limit.
Does that help?
