Revoking a Voluntary Acknowledgment of Paternity (AOP) in Colorado: The 60-Day Rule

Signing a birth certificate at the hospital is supposed to be a joyful occasion. By signing a Voluntary Acknowledgment of Parentage (VAP, historically referred to as an AOP), unmarried parents legally establish the man as the child's father, placing his name on the official birth certificate. But what happens if you later discover evidence suggesting you are not the biological father? In Colorado, acting quickly is a matter of legal survival.

The state treats a signed AOP with the exact same weight as a judge's court order. If you allow the brief rescission window to close, untangling yourself from the legal and financial obligations of fatherhood becomes a monumental task. Whether you reside in Denver, Grand Junction, or Greeley, understanding the precise administrative steps to revoke an AOP is vital. If you are running out of time or facing a hostile situation with the mother, finding a skilled family law attorney in our US Lawyer Directory can provide you with the aggressive representation you need.

Understanding the 60-Day Automatic Rescission Window

Colorado law provides a very brief grace period for "buyer's remorse" when it comes to acknowledging parentage. Under C.R.S. § 19-4-105, either the mother or the father who signed the acknowledgment has exactly 60 days from the date the form was signed to legally revoke it. You do not need to provide a reason, you do not need a DNA test, and you do not need a judge's permission.

To utilize this 60-day rule, you must properly submit a rescission of the Form VR-12, Colorado, Colorado Department of Public Health and Environment, Voluntary Acknowledgment of Parentage. This document must be signed, notarized, and physically received by the Colorado Department of Public Health and Environment, Denver before the 60th day expires. Once accepted, your legal status as the father is erased, and your name is removed from the birth certificate.

Proving Fraud or Material Mistake of Fact After 60 Days

If day 61 arrives and you have not filed the rescission, the acknowledgment becomes a permanent, binding legal judgment. You can no longer simply mail a form to the health department. To challenge parentage after 60 days under C.R.S. § 19-4-105(2), you must file a formal lawsuit in the District Court using Form JDF 1514, Colorado, Judicial Branch, Petition to Disclaim Paternity or file a Form JDF 1525, Colorado, Judicial Branch, Motion to Modify or Set Aside a Parentage Order. You carry the heavy burden of proving that you signed the document because of fraud, duress, or a material mistake of fact. For instance, you must prove the mother intentionally lied to you about her fidelity, and that you reasonably relied on her lie when you signed the paper.

What to Do if the Mother Blocks the Revocation

Within the initial 60 days, the mother cannot block your administrative rescission; it is your unilateral right. However, if you are past the 60 days and must file a lawsuit, she can aggressively fight you. She might refuse to submit the child for a DNA test or argue that you always knew there was a chance you weren't the father but signed anyway. In these contested cases, your attorney must file a motion to compel a court-ordered genetic test and serve her with a formal summons to appear before a judge.

How Much Does it Cost to Rescind an AOP?

The cost of revoking your paternity depends entirely on whether you catch the issue within the first 60 days.

How Long Does the Process Take?

If you act within the 60-day window, the CDPHE usually processes your mailed rescission form within 2 to 4 weeks, swiftly updating the vital records. If you miss the deadline and have to file a lawsuit in District Court to prove fraud, the process slows to a crawl. A contested paternity case involving discovery, mandatory mediation, and a final hearing can easily take 4 to 8 months to resolve.
