Can a patient sue her doctor for medical negligence after signing an informed consent agreement in Texas? I think my pregnant daughter's doctor had no right to accept an informed consent from my daughter since she is only 17 years old. She is single and lives on her own independently. But now she is complaining about feeling sick after treatments that the doctor gave her for her pregnancy. I think as her mother I should be the one that must give consent to a doctor for my minor daughter's medical care and treatment.
