Imputing Income
The act of awarding potential income to individuals not employed or voluntarily underemployed; the CSEA or court may project utilizing the child support guidelines, an income base for purposes of establishing a support obligation.
Your spouse could make the same claim that he also feels he should be in the home raising his children. She has a financial responsiblity to her children just as much as he does. If she were to get divorced or her husband died and she had no income, she would probably be getting a job doing what she knows how to do to support the children.
I would find any State Statute I could find regarding potential income.
