Need advice. Trying to help my SIL. She has primary custody of my nephew age 14. Her ex is supposed to have his son 70 days/yr. He lives with his girlfriend, in a house that SHE owns, and she is a very heavy smoker. Nephew has declared he doesn't want to go over there anymore because he can't stand the smoke. It's been 6 months since divorce was final, and the son has only spent about 10 days at his dad's. My SIL is wondering if she can go to court to (1) increase her support, since dad is not taking his son enough so it is costing her more for food, etc, and (2) to either stop the smoking (yeah, good luck with that) or force the dad to take son somewhere without smoke. Any advice, anyone been there before? Is this all worth engaging her attorney again?
