Can she get the court to deny my papers?

No surprise that she wants you gone! You are messing up her child support and maybe welfare cases. You give her money now, but child support is good for 18 years. You should talk to her about these things, before you mess with her life. Call your Ex and talk to her. Tell that you were just trying to do the "right" thing for your daughter. Work something out so you can still be a part of your daughter's life, without messing with your Ex's life. Some money to help with cost of raising the girl is a good start. It's a tough world, work together for your daughter. Not against each other. A little give and take, is not losing, it's working together to help your daughter win. I wish you luck; my daughter is the most wonderful to happen in my life.
