Legal Name Changes
The Colorado statutes governing name changes can be found at C.R.S. § 13-15-101 et. seq. Colorado uses form pleadings. The official pleadings issued by the Colorado Judicial Branch are available here.
For more information about how to change your name, what to do after your name change, and to get sample pleadings you can visit the Colorado Name Change Project.
If you are between the ages of 18 and 69 and have never been convicted of a felony, you may be able to use this interactive site to help you generate your own Colorado name change forms.
The Colorado Courts have special procedures for children, people 70 and older, and people who have been convicted of a felony. Form more information, please see the Colorado Judicial Branch.
Gender Marker Change for Colorado ID
The DMV allows Coloradans to amend the gender marker on their ID or driver’s license with form DR-2308. Adults can self-attest to their gender identity without certification from any other party, such as a health care provider. Minors must have the their parent or guardian’s attestation and certification from a licensed medical or mental health care provider from any state and they will attest that you have undergone surgical, hormonal, or other treatment for gender transition or that you have an intersex condition. Medical sex reassignment surgery is not necessary to change your gender marker on your ID or birth certificate in Colorado. Note that this form may only be completed by a licensed medical or mental health care provider. You can change your gender marker to male, female, or X.
Note: changing your gender marker with the DMV on your ID does not change your gender marker on your birth certificate. You do not have to amend your birth certificate before you can amend the gender on your ID or driver’s license.
Gender Marker Change for Colorado Birth Certificate
The Colorado Department of Health and the Environment (CDPHE) oversees birth certificates and other vital records. Information about how to amend the name and gender marker on your birth certificate is available here. You will need the Birth Certificate Correction form and the Sex Designation form. Note that sex designation can be changed by self-attestation for adults. Minors can change their sex designation on their birth certificate with a certified statement from a licensed medical or mental health care provider from any state, attesting that, in their professional opinion, the sex designation on your Colorado birth certificate does not accurately reflect your gender identity and your sex designation should be changed accordingly. You can change your sex designation to male, female, or X. For minors, their parent or guardian must sign the Birth Certificate Correction form.
Gender Marker Change for US Passport
If it is easier to change your gender marker on a US passport than to amend your Colorado birth certificate, you may want to get a passport that reflects your correct gender. A passport is an all-in-one identity and lawful presence document. That means if you have an unexpired passport, you can show that to employers as proof of your identity and eligibility to work in the United States. It also works for travel and all other transactions where you need to demonstrate your age, identity, or citizenship. Passports are valid for ten years for most people, whereas no state ID or driver’s license may be issued for more than eight years.
For more information, check with the US Department of State.
