Is someone saying that you have a child? If you don't think you are the father, then you need to consider a paternity test. If someone else is saying that they are the father of a baby that you believe to be yours, a paternity test is also needed. If a test is performed and you believe that the paternity is inaccurate, you will want to challenge the results. Essentially, there are three primary ways in which you can challenge a paternity test.

1. The Lab Results Were Fraudulent or Tainted.

Lab results are not always 100 percent accurate, and this can be for a number of reasons. If there is proof that there has been second-rate work in the lab in previous months or years, then you may be able to use this to challenge the test. In some cases, labs make administrative errors and could have accidentally switched your lab results with someone else's or simply input the wrong information. After all, it is possible for people to make mistakes. Also, keep in mind that if an individual poses as you and takes the test, they have committed a fraudulent act.

2. Sterility or Infertility.

If you can prove that you're infertile or sterile, you may be able to prove that there is no way you can be the father. If it is 100 percent impossible for you to help a woman conceive a baby, then you are clearly not the father no matter how much she or anyone else wants to say that you are. If this sounds like a factor in your particular situation, then this is something that could help take your case to the next level. Schedule an appointment with primary care physician to have testing done and obtain your results in writing to provide to the mother or the court.

3. The Mother Cheated.

If you know you aren't the father, then someone else is. If you have proof of the mother's infidelity, then you will have leverage to challenge the paternity test. You will want to document any names of men that you believe or know that the child's mother has been with or could be the father. The more proof that you can gather, the more likely you'll be able to successfully challenge a paternity test.

Each state has its own set of rules regarding what can and cannot be done when challenging paternity tests. Therefore, it is generally in your best interest to consult with an experienced family law attorney like one from Law Office of Shelli Wright Johnson who has experience with paternity cases to discuss your specific circumstances and determine how to proceed.
