What is the name of your state (only U.S. law)? California. I am non custodial parent of an 11 year old child. The mother lives with her boyfriend and has three children with him. She did her wage and expense declaration and claimed her three children plus my daughter and her income. I want to know if she lives with her boyfriend ( the father of her other children), is it law that she reports his income, because he does work and they live together? Please advice.What is the name of your state (only U.S. law)?
