My question involves bankruptcy in the state of: California

I am working with an attorney and hope to file a Chapter 7 bankruptcy.

In determining my household size and median income, my attorney indicates that I can only use the number of people I claimed on my latest income tax return. I claimed a total of four people people on my latest income tax return (myself, my wfie and two children).

But I have a total of nine people living in my house. I cannot claim all of the nine people on my income tax return because some of them have part-time jobs and make too much money for me to claim them. They DO NOT contribute any money to food costs or to upkeep of the house.

How many people can I claim in determining my household size?

Thank you
