In Colorado, minors do not need parental consent to receive an abortion. However, state law does require that they notify their parents/guardian at least 48 hours before the procedure. A minor can choose to notify her parents herself (with a certification form), or she may choose to have her abortion provider send notification by certified mail. She may also ask a judge to excuse her from this requirement, particularly if telling her parents would place her in danger.
In other words, no. If you are under 18 and seeking an abortion in Colorado, you are required to tell a parent unless you are in danger or a victim of incest/abuse.
In some states, parental notification is not required. To learn more about abortion laws by state, check out this Guttmacher Institute Fact Sheet. If you are pregnant and not sure what to do, give Teen Clinic a call. We offer free, unbiased decision counseling and referrals.
