Montana Title 41. Minors § 41-1-404. Financial responsibility of minor

Consent of the minor shall not be subject to later disaffirmance or revocation because of minority. The spouse, parent, parents, or legal guardian of a consenting minor shall not be liable for payment for such service unless the spouse, parent, parents, or legal guardian have expressly agreed to pay for such care. Minors so consenting for such health services shall thereby assume financial responsibility for the cost of said services, except those who are proven unable to pay and who receive the services in public institutions. If the minor is covered by health insurance, payment may be applied for services rendered.
