Keep Lilly with Chasity Silver

I was given costody of Lilly about 2 years ago and all was fine until I asked for child support now her parents are taking me to court to get her back. I feel that this would be very detrimental to Lilly and her well being.  To protect Lilly I'm not going to say what she said happened to her but just know that she does not belong with her parents. Please help me convince the judge that Lilly should stay where she is happy and most importantly SAFE.  Thank you all so much for your support.
