Can I sue school district for letting childs mother withdraw her from school with out my knowledge or consent?

I had "physical possession" and had filed suit affecting child parent relationship. I enrolled her in school and listed who could withdraw her and her mother was not listed. The child was skipping school and was caught so she called mother told her she wanted to move back and mother went to school and withdrew child, school did not call me or email or nothing. I called school and they said "she had very old custody paper" and they let her withdraw her. She has now living on street and with friends again and not attending school and has 19 yr old boyfriend. I sit and feel like my whole life has changed due to the school not following there own procedures.
