Understanding Paternity Test Results

Understanding the results of a paternity test is important for interpreting the genetic information accurately and addressing any questions or concerns you might have. Paternity tests are highly reliable, but interpreting the results requires some knowledge of genetic principles and the testing process.

What Does a Negative Paternity Test Look Like?

A paternity test is designed to confirm or exclude biological fatherhood by comparing DNA markers between the alleged father and the child. A negative paternity test result indicates that the tested individual does not match the genetic markers of the child. This is usually presented in the test report through a low Combined Paternity Index (CPI) and a probability of paternity approaching 0%. The Genetic System Table will display various loci (specific locations on the DNA) where the child’s and alleged father’s genetic markers are compared. Significant mismatches in these markers confirm that the alleged father is not the biological father.

Can a Negative Paternity Test Be Wrong?

While negative paternity test results are highly accurate, there is still a very small chance of error. Possible errors can arise from sample contamination, lab errors, or issues during sample collection. Accredited laboratories like DNA Diagnostics Center (DDC) follow rigorous procedures to ensure accuracy and minimize errors. If you believe the results are incorrect, you can request a retest or additional analysis to confirm the findings. It’s also essential to ensure that the testing process was correctly followed to rule out any procedural mistakes.

What Percentage of Paternity Tests Are Negative?

Negative paternity tests are relatively uncommon but do happen. The majority of paternity tests confirm the biological relationship between the alleged father and the child. However, the percentage of negative results can vary depending on the specific circumstances and the accuracy of the testing process. It’s important to remember that the primary goal of paternity testing is to provide accurate results based on genetic evidence.

If You Never Married Your Partner

1. You Never Claimed the Child Legally

If you and your partner were not married and you did not sign a Voluntary Acknowledgement of Paternity document or the birth certificate, but you wish to maintain your relationship with the child, pursuing legal guardianship is an option. This process involves filing a petition with the court to become the child’s legal guardian.

Legal Guardianship Requirements

To qualify for legal guardianship, you must meet several criteria:

  • Legal Adult: You must be at least 18 years old.
  • Capacity to Care: You need to demonstrate that you have the time, resources, and ability to care for the child.
  • Financial Stability: You should be able to provide for the child’s needs.
  • Physical and Emotional Capability: You must be physically and emotionally capable of fulfilling the responsibilities of a guardian.
  • Positive Influence: You need to show that you would be a positive role model and influence in the child’s life.

The court will evaluate these factors and make a decision based on the best interests of the child. If the biological parent(s) consent to your guardianship, the process is generally smoother. If the biological parents do not consent, guardianship might still be pursued if the parents are deemed unfit to care for the child.

2. You Claimed the Child Legally

If you signed the birth certificate or a Voluntary Acknowledgement of Paternity, the situation becomes more complex. In many jurisdictions, even if a paternity test shows you are not the biological father, you may still be required to provide child support if you have previously acknowledged paternity. Reimbursement for past child support payments is usually not available. Some states offer a legal process to disestablish paternity, which can relieve you from future support obligations but often does not include reimbursement for past payments.

Disestablishing Paternity

Disestablishing paternity is a legal process that can be complex and varies by state. It typically involves:

  • Filing a Petition: You will need to file a petition in family court to challenge paternity.
  • Providing Evidence: You must provide evidence, including the results of the paternity test, to support your claim.
  • Court Hearing: A court hearing will be held to review the evidence and make a determination.
  • Legal Advice: Consulting with a family-law attorney is crucial to navigate this process effectively.

If You Are/Were Married to Your Partner

In cases where the child was born during your marriage, you are typically presumed to be the legal father. This presumption holds even if a paternity test reveals you are not the biological father. The emotional impact of this discovery can be profound, as it challenges the foundation of your relationship with the child.

Emotional Considerations

The emotional fallout from discovering you are not the biological father can be significant. Many men experience feelings of betrayal, anger, and confusion. It’s important to acknowledge and address these emotions, whether through counseling, support groups, or personal reflection. The decision to continue supporting and maintaining a relationship with the child, despite the paternity results, can be a deeply personal one.

Maintaining Relationships

For many fathers, the emotional bond with the child they have raised remains strong regardless of biological ties. In cases like Chris’s, where the child is the result of an affair but has known only one father figure, maintaining that relationship can be beneficial for the child’s emotional well-being. Many men choose to continue supporting and loving the child, recognizing that their role as a father extends beyond biological connections.

Confirm Paternity Before Signing Legal Documents

To avoid the complications of a negative paternity test result, it’s advisable to confirm paternity before signing legal documents such as birth certificates or Voluntary Acknowledgements of Paternity. This proactive approach helps prevent legal and emotional challenges down the line.

Prenatal Testing

Non-invasive prenatal paternity testing is an option for confirming paternity before the child is born. This test uses a blood sample from the mother and the alleged father to determine paternity with high accuracy. Early testing can provide clarity and prevent potential legal disputes or emotional distress.

Child Support After a Negative Paternity Test

Understanding your obligations regarding child support after a negative paternity test is crucial. In many jurisdictions, if you have legally acknowledged paternity, you may still be required to pay child support, even if a paternity test reveals you are not the biological father. However, some states have provisions for modifying or terminating child support obligations based on new evidence of paternity.

Modifying Child Support Obligations

To modify child support obligations, you typically need to:

  1. File a Motion: Submit a motion to the court requesting a modification of support obligations.
  2. Provide Evidence: Present the paternity test results and any other relevant evidence.
  3. Court Review: Attend a court hearing where a judge will review the evidence and make a decision.
  4. It’s important to consult with a family-law attorney to understand the specific procedures and requirements in your state.

Custody and Visitation Rights

Your rights to custody or visitation are generally not affected by a negative paternity test if you have been an active parent. Courts prioritize the child’s best interest, and maintaining a stable relationship with the child is often considered crucial. If you wish to pursue changes to custody or visitation arrangements, legal advice and court intervention may be necessary.

Addressing the Emotional Impact

Dealing with the emotional impact of a negative paternity test requires a thoughtful approach. Some strategies include:

  1. Counseling: Seeking therapy or counseling can help process emotions and provide support during this challenging time.
  2. Support Groups: Joining support groups for fathers or individuals in similar situations can offer valuable emotional support and guidance.
  3. Open Communication: If appropriate, communicate openly with the child’s mother or other involved parties to address any concerns or questions.

Maintaining a Healthy Relationship

For those who choose to remain involved in the child’s life, maintaining a healthy and supportive relationship is important. Focus on being a positive influence and providing emotional stability for the child, regardless of biological ties.

Receiving a negative paternity test result is a complex and multifaceted experience that can have significant legal, emotional, and practical implications. Understanding your options and taking appropriate steps can help you navigate this challenging situation. Whether you seek to maintain your role in the child’s life, address legal responsibilities, or challenge the results, consulting with legal and emotional support professionals can provide valuable guidance tailored to your specific circumstances.

Frequently Asked Questions

1. What should I do if a paternity test shows I’m not the biological father?

If a paternity test reveals that you are not the biological father, the next steps depend on your legal and emotional situation. You may need to consult a family-law attorney to understand your legal obligations and rights. If you have been actively involved in the child’s life, you might want to explore options for legal guardianship or custody to maintain your relationship with the child.

2. Can a paternity test be wrong?

While paternity tests are highly accurate, errors can occur due to factors such as sample contamination or incorrect handling. However, such errors are rare. If you have concerns about the accuracy of the results, it may be advisable to undergo a second test or consult with a genetic counselor for further clarification.

3. What happens to child support obligations after a negative paternity test?

If a paternity test shows you are not the biological father, you may still be responsible for child support if you have previously acknowledged legal paternity. Some states allow for the disestablishment of paternity, which could end your obligation to pay child support, but reimbursement for past payments is generally not available. Consulting a family-law attorney can help you navigate this process.

4. What does a negative paternity test result look like?

A negative paternity test result indicates that the alleged father is not the biological parent of the child. The report typically shows a Combined Paternity Index (CPI) of zero or a very low value, and the conclusion section will state that the alleged father is “excluded” as the biological father.

5. What percentage of paternity tests are negative?

The percentage of paternity tests that return a negative result can vary. In general, a low percentage of tests are negative, especially when there is a high level of suspicion about the biological relationship. For specific statistics, you might refer to data from testing laboratories or research studies related to paternity testing.

    My son is 11 months old and I am in the BC. I have been there since the very beginning, doctor visits, delivery room, etc. He is my world. I left the mother after a second domestic violence issue where she attacked me while holding the baby who was 6 months at the time. She also turned into a major drug addict as well. DCF is involved and see the baby is well taken care of in my care and after trying to talk to her and trying to get her to drug test have stated she shouldn’t have an authority over an child. Refusal of drug tests counts as positive drugs tests so it marks her for 3 positives. She has now tried to have a emergency removal of my son back to her and the judge stayed that if DCF says the child can go back then he does and refused to see or hear my evidence I have on the drug use and violence. She has also filed to have a paternity test done to determine if I am the father or not. There is a possibility he may not be mine due to a time she did cheat. As I stated earlier I did sign the BC and I do believe and treat him as my own. If it turns out he isn’t, will I lose him forever? I don’t want to lose him.

    Hi, I live in Illinois and I have always wondered if this now 18 year old girl is my child. My and her mother entered into a relationship while in college when we were 20 & 21. We broke up like most do, and I found out a short time later she was pregnant and in a new relationship shortly after our breakup. She at the time denied the baby was mine and that I didn’t need to worry. She ended up marring the man she dated after me, had the baby girl and more kids even after that. They have been happy and married ever since. I did reach out after the said baby was born, and she again said it wasn’t mine! I’ve lived wondering for the past 18 years of her first born was mine or not. I recently reached out to the child outside of the mother’s and father’s knowledge and got a paternity test. Results should be back soon. What are my next steps if I am her biological dad, and next legal recourse, if any? I’m sure this will disrupt all their lives a lot, and will bring clarification to this child and me. Can the parents stop me, if she still lives with them? What are all the limitations? I am unmarried, and do my own thing living on my own. Both other parents are well off, and I’m doing well myself. Just looking for answers and to find out if she is mine or not.

      Hi, Jack. Because the young woman you tested with is an adult, she was eligible to have a DNA test done without her parents’ consent. As for next steps, all your questions are best answered by a family-law attorney where you live.

    Bonjour, 1st, sorry for my english…
    I am divorced but later learned that 2 of my four kids are not mine (#1 and #3). My Daughter learned the news the same time as me, she was 21 and took it lets say pretty well but made a comment “I am glad I discovered this now and not younger or in high school or during university, It will have been very hard”. Because of this comment, I have not told my 15 year old son.
    He is very very attached to me but one day I will have to tell him. I know there is no good or best time I believe to tell the truth but I will have to. I am afraid that he will say what haven’t you tell me earlier, or you lied to me all those years etc… I am scare of that but I think after my daughter comment it is the less bad way to do, so I will wait.
    Also, we talk about the kids but the father in all of this… what about him? It is not easy for him, for me. I married her for love and she was pregnant from someone else and I feel (I know it can sound terrible and selfish, and I adore my kids) like some how she stole my life because I will not have married her if I knew it was not my kid…
    All of this to say that it is not easy for both side but the truth need to be said and the right moment if there is one will come as an evidence.
    Merci for reading
    I

    I have a son, his father did a paternity DNA test and it came out to be nagetive, but the problem is, my son look like his father. And am sure is was a wrong DNA test because they didn’t even show the percentage and they just told me that my son is mine but not the father his father. I wanted them to prove it to me, but they told me they can’t. Please show me what to do.

      Hello, Prudence. The laboratory should be able to go over the test report with you and explain through the data why it is an exclusion. You may want to do a test with a different lab.

      Hi, Lily. If the test is a court-admissible one that requires a chain-of-custody process and witnessed DNA collection and submission, then you can be confident it’s his DNA being tested.

    My soon to be husband just had a woman come forward and say that her almost 6 year old is his. He does not believe it’s his and says if it is that he does not want to be a part of the child’s life. Is he able to sign his rights away to this child

    My ex Gf contacted me and told me I have a 1year old son so we did a DNA test and the results shows that I’m not the biological father. She now wants to take me to court because she’s not satisfied with the results. What can I do as this is soo much stress… I want her to leave me alone

    Reply
    • DDC

      Hi, Grant. You are under no obligation to do anything or agree to anything unless the court compels you to. If the court finds reason to order a legal paternity test with witnessed DNA collection and you don’t comply, you risk having the court rule you to be the biological father even if a test would have shown you’re not.
