my autistic daughter who lives in a group home filed a restraining order against me her mother I want to fight it what do I do

You will need to be  personally served with the restraining order and notified of the court date. The restraning order is initially issued on a temporary basis, and than there is usually a full blown hearing which you can testify and defend yourself on, regarding the request for a more permanent restraining order, if based on harassment or domestic violence.
