The surrender form means that you surrendered all rights to your child. You can inquire at the court as to the name change. You then have to file a motion to vacate the name change for lack of notice unless it was published. Why does it matter what what your daughter's last name is if you knowing and voluntarily signed over your rights? If they did go through with an adoption, her name would have been changed anyway. Are they pursuing you for child support or other? It will be difficult to change anything that they have done due to the form you signed.
