The Colorado Constitution, Article 12, Section 8, requires persons holding a position of civil office to take a constitutional oath or affirmation of office, before taking public office.
Section 8. Oath of civil officers.
Every civil officer, except members of the general assembly and such inferior officers as may be by law exempted, shall, before he enters upon the duties of his office, take and subscribe an oath or affirmation to support the Constitution of the United States and of the state of Colorado, and to faithfully perform the duties of the office upon which he shall be about to enter.
Section 9. Oaths where filed.
Officers of the executive department and judges of the supreme and district courts, and district attorneys shall file their oaths of office with the secretary of state; every other officer shall file his oath of office with the county clerk of the county wherein he shall have been elected.
The Colorado Secretary of State provides a fillable PDF file of the Colorado Oath of Office form on the SOS website.
The oath or affirmation must be administered by an authorized official, including a Colorado notary public.

The signed oath of office must be filed with the secretary of state or the county clerk as described in 24-12-101(3).
Colorado Notary Oath of Office
In the past, a Colorado notary public took a Constitutional oath of office. Colorado statute CRS 24-21-521(5) now requires a notary to take an affirmation to faithfully perform all notarial acts in conformance with the law.
There is no longer a reference in the notary affirmation to support the Constitution. But, there is no prohibition against a notary taking a Constitutional oath of office.
