cost sharing vs rent

[user17735011071]

Grandson gives me $200 a month for rent or should it be cost sharing. he is on disability and helps with his childs expenses. So far for the past three months utilities have trippled. He doesn't contribute towards food any more. I'm on a fixed income (retired) I make no money from what he gives me. He's 30 years old now but needs a place to stay. I feel it should be cost sharing not rent.

Yes, that is cost sharing.

If he lives with you, then it is cost sharing.
