Not in most cases. A consent form will never be interpreted by a court to constitute consent to medical malpractice – a doctor is always required to treat you with a professional degree of care, regardless of whether you sign a consent form or not. Just about the only situation in which a consent form could be relevant would be if your claim asserted that you were not given the opportunity to consent to a particular treatment, and that you would not have consented to the treatment if you had known of its risks.
