Oregon Revised Statutes Domestic Relations § 109.575

(1) A relative caregiver acting pursuant to an affidavit under ORS 109.580 may consent to medical treatment and educational services for a minor child that a minor child cannot otherwise legally consent to if, after reasonable efforts have been made to obtain the consent of the legal parent or guardian to the treatment or services, the consent of the legal parent or guardian cannot be obtained.

(2) A relative caregiver providing consent under this section is liable to the health care provider or school for payment for any medical treatment or educational services provided to a minor child pursuant to the consent.

(3) The consent of a relative caregiver under this section shall be superseded by any contravening decision of the legal parent or guardian, provided the decision does not threaten the life, health or safety of the minor child.

(4) If the minor child stops living with the relative caregiver, the relative caregiver shall immediately notify any health care provider or school that has been given an affidavit under ORS 109.580. The affidavit is invalid immediately upon receipt by the health care provider or school of the notice under this subsection.

(5) An affidavit under ORS 109.580 expires one year after the date it is given to a health care provider or school by a relative caregiver. If the date the affidavit is given to a health care provider or school is unknown or uncertain, it shall expire one year after the date the relative caregiver signs the affidavit.

(7) A relative caregiver acting in good faith with reasonable grounds to provide consent for medical treatment or educational services pursuant to an affidavit under ORS 109.580 is not subject to criminal or civil liability that might otherwise be incurred or imposed for giving consent to the medical treatment or educational services.

(8) Nothing in this section relieves a legal parent or guardian of liability for payment for medical treatment or educational services provided to a minor child pursuant to the valid consent of a relative caregiver under this section.
