Many people incorrectly assume that signing an informed consent waiver prevents them from suing for medical malpractice if the procedure goes wrong. Informed consent waivers do NOT prevent patients from suing for medical malpractice if the doctor is negligent in performing the medical procedure. No release form can ever bar an injured patient from suing for medical negligence. The law does not allow doctors (or anyone else) to make themselves immune from negligence liability through waivers.
