A Comprehensive Guide to Obtaining a DNA Test in a Texas Court


In recent years, the role of DNA testing has become increasingly prominent in legal proceedings, particularly in family court cases. Whether it’s establishing paternity, determining familial relationships, or resolving issues related to child custody, a DNA test can provide concrete evidence to support or challenge claims. If you find yourself in a situation where a DNA test is crucial to your case in a Texas court, this comprehensive guide will walk you through the process, legal considerations, and steps involved in obtaining a court-ordered DNA test.

Understanding the Need for a DNA Test

Before delving into the procedural aspects, it’s essential to understand when and why a court may order a DNA test in Texas. Typically, these tests are requested in cases involving:

  1. Paternity Disputes: When the biological father of a child is in question.
  2. Child Custody Battles: DNA tests may be ordered to determine the biological relationship between a parent and a child, impacting custody decisions.
  3. Inheritance Claims: In cases where familial relationships are contested for matters of inheritance.
  4. Adoption Proceedings: DNA tests can play a role in verifying biological relationships in adoption cases.
  5. Immigration Cases: Establishing biological relationships is crucial in certain immigration proceedings.

Initiating the Process

Step 1: Consult with an Attorney

Given the complexity of legal matters, especially those involving DNA testing, it is advisable to consult with an experienced family law attorney. They can provide personalized advice based on the specifics of your case, ensuring that you navigate the legal landscape effectively.

Step 2: File a Petition

Your attorney will guide you through the process of filing a petition with the appropriate court. This legal document formally requests the court to order a DNA test and outlines the reasons supporting your request. Ensure that all relevant details and supporting documentation are included in the petition.

Legal Considerations

Texas Family Code

The Texas Family Code governs family law matters in the state. Specifically, Section 160.501 addresses genetic testing to determine parentage. Familiarize yourself with this section, as it outlines the legal framework for obtaining a DNA test in paternity cases.

Best Interests of the Child

Texas family courts prioritize the best interests of the child when making decisions. If the court deems it necessary to establish paternity through DNA testing for the welfare of the child, they may order it.


In some cases, all parties involved may voluntarily agree to a DNA test. However, if one party refuses, the court may intervene and order the test.

The Court Process

Preliminary Hearings

After filing the petition, the court may schedule a preliminary hearing to review the case and determine if there are sufficient grounds to order a DNA test. This hearing allows both parties to present their arguments.

Court-Ordered DNA Testing

If the court finds merit in your case, they will issue an order for DNA testing. The order will specify the type of test, the individuals involved, and the authorized testing facility.

Selecting a DNA Testing Facility

The court order will likely include guidelines on choosing an accredited DNA testing facility. It’s crucial to select a reputable and certified laboratory to ensure the admissibility of the test results in court.

Collecting Samples

Once the testing facility is selected, all parties involved will need to provide DNA samples. This typically involves a simple and non-invasive process, such as a cheek swab.

Admissibility of Results

Upon completion of the DNA test, the results will be provided to the court. It’s essential to work closely with your attorney to ensure the proper presentation of the results and their admissibility in court.


Obtaining a DNA test in a Texas court involves a multifaceted legal process, emphasizing the importance of understanding the relevant laws, court procedures, and best practices. Navigating this journey successfully requires collaboration with a knowledgeable family law attorney, adherence to legal protocols, and selecting a reputable testing facility. By following the steps outlined in this guide, you can approach the process with confidence and increase the likelihood of achieving a fair and just resolution to your case.
