If she can convince the trustee that you in no way support her financially, or contribute to the household, it is possible, that the trustee would allow your income to be not included.
Did she list her marital status as married or seperated?
If you are living as a married couple, she would be required to atleast list your income, and what you contribute in the monthly expenses, in no way will you be affected by the information, but she may be denied a discharge without it.
For example, if she is unemployed, and lives with you in the house, she cannot list 0 as income, the Court requires her to list your income, as part of the household income that helps her pay her expenses.
