Disestablishing Paternity in Connecticut: What to Do if You Discover You Are Not the Biological Father

Discovering that you are not the biological father of a child you have been raising is a deeply emotional and legally complex crisis. In Connecticut, if you signed an Acknowledgment of Parentage (AOP) more than 60 days ago, or if you were declared the father through a default court judgment, the state views you as the legal father. Overturning this-known as disestablishing paternity-is one of the most difficult battles in family law. Whether you reside in New Haven, Bridgeport, or Greenwich, you must act quickly to protect your long-term assets and legal rights before the court decides that maintaining the status quo is in the best interest of the child.

Step-by-Step Process to Disestablish Paternity in CT

To successfully remove your name from the birth certificate and stop child support, you cannot simply show the judge a private DNA test. You must meet a very strict statutory standard under Connecticut law to reopen the case.

Step 1: Understanding 'Material Mistake of Fact, Duress, or Fraud'

Under the C.G.S. § 46b-450, specifically C.G.S. § 46b-483, once the statutory 60-day rescission window expires, an Acknowledgment of Parentage can only be challenged in court on three exclusive grounds:

• Fraud: The other party intentionally deceived you, knowing you were not the biological father, to induce you into signing the acknowledgment.
• Duress: You were threatened, coerced, or forced into signing the document against your free will.
• Material Mistake of Fact: Both parties genuinely believed you were the biological father based on erroneous factual assumptions.

Even if you demonstrate fraud, duress, or a material mistake of fact, the court will evaluate whether granting relief aligns with the best interest of the child under the statutory criteria of C.G.S. § 46b-475 before ordering genetic testing or setting aside parentage.

Step 2: Discovering the Truth via Commercial DNA Kits

Many men today uncover paternity discrepancies through commercial kits like 23andMe or AncestryDNA. While these tests are emotionally devastating, they are typically not admissible in a Connecticut Superior Court due to a lack of certified chain of custody. However, discovering this evidence triggers the clock. Once you know you might not be the father, you must file a petition to disestablish paternity immediately. Waiting years to file after seeing a commercial DNA result can cause the court to dismiss your claim under principles of laches or equitable estoppel.

Step 3: What if the Child is Now a Teenager?

Connecticut family courts prioritize the best interest of the child above biological ties. Under C.G.S. § 46b-475, if you have raised the child for many years, the judge may refuse to disestablish paternity, ruling that breaking the psychological bond and cutting off financial support would cause substantial harm. This principle of equitable estoppel, affirmed in W. v. W., 256 Conn. 657 (CT Supreme Court 2001), means that the longer you act as the father, the harder it becomes to disestablish legal parentage.

Step 4: Asset Protection for High-Net-Worth Individuals

For high-net-worth individuals in Fairfield County or Stamford, paternity fraud carries massive financial exposure, including substantial child support orders and legal inheritance rights. It is vital to consult a lawyer to challenge paternity as soon as doubts arise. A successful disestablishment terminates ongoing child support obligations and severs the child's legal right to inherit from your estate under Connecticut probate laws.

Step 5: Filing a Petition in Superior Court

To initiate the process, you must use our US Lawyers Directory to find a seasoned family law attorney. They will file a petition to adjudicate parentage or a formal Motion to Open Judgment in the Connecticut Superior Court, Family Division, New Haven, Connecticut Superior Court, Family Division, Bridgeport, or Connecticut Superior Court, Family Division, Hartford. If the judge agrees that there is sufficient prima facie evidence of fraud, duress, or mistake and that it serves the child's best interests under C.G.S. § 46b-475, the court will order official genetic testing under C.G.S. § 46b-497.

How Much Does it Cost in Connecticut?

Disestablishing paternity involves significant legal and procedural expenses. The court filing fee is $360 for an initial petition to adjudicate parentage under C.G.S. § 52-259(a), or $180 if filing a Motion to Open Judgment under C.G.S. § 52-259c(a). An official, court-admissible genetic test usually costs between $300 and $500. Because these cases require proving complex legal elements like fraud or mistake under C.G.S. § 46b-483, hiring private counsel is essential. Attorney fees for a contested paternity disestablishment case generally range from $5,000 to $15,000, depending on whether the mother or the Connecticut Department of Social Services, Hartford contests the proceeding.

How Long Does the Process Take?

This is not a quick process. From the moment your attorney files the initial motion to the final ruling by a judge, you can expect the litigation to take anywhere from 6 to 12 months. During this time, you must continue to pay any court-ordered child support. Stopping payments without a court order can result in you being held in contempt of court.
