You may have to have yrou chidl declared emancipated, in order to escpe liability for the hospital bill. But, it may be worht the try to deny the bill because, A) you child did not reside with you at the time of the bill, an d B) you did not give them consent to do anythiung to your child. But, if the bill was for necessary servcies, as opposed to an elective procuedure, you may not be able to escape the bill. If you had done the emaciaption claim earlier you might have.

Good luck
