washington state- Does anyone know if you're allowed to address back support in this situation? She has one kid, he has the other. He has continued to pay support for the child in her care, she has paid nothing for the child in his care. When he goes to court can back support be legally addressed in an order for the time the child has been in his care? Also, can transportation costs be addressed as a back support issue? Can emails be used to support your case in court?
