My ex wife is refusing to provide pertinent financial information in regards to child support modification. She is not working by choice and is living off of her husbands significant income. While I realize she has the legal right to do so, I also understand that her potential income is to be imputed into the child support calculator. This would be calculated by averaging the income reported for income tax purposes for the last 3 years she worked. The problem is that the law only requires her to provide the past 3 years and she hasn't worked since 2008. Pattern Interrogatories/Request of Documents requested tax docs 2006-2008. Now I need to file a Motion to Compel. However, this motion again only asks for the past 3 years of tax information. What can I do to get the information I need?
