Specimens we can test for DNA

The easiest and most reliable way to obtain a DNA sample for paternity testing is to swab the inner cheeks of the alleged father and child or children. These skin cells are known as buccal cells, and they rub off easily onto cotton swabs and remain in place for analysis by our laboratory.

Other specimen samples, such as hair follicles, fingernails, and garments that might contain someone's DNA, can also be tested. An Alternative Specimen DNA Test is done by ordering one of our testing kits online and shipping the specimens back to us.

Legal DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. Accurate results for DNA paternity testing with 99.99% confidence or greater take about a week.

When deciding which type of DNA test is right for you, consider first what you might do with the results. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Brownsville DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Presumption of Paternity in Texas

When a child is born to a married couple, the mother's husband is presumed to be the child's biological father. According to attorneys at Brownsville-based Gracia Law Firm, the presumption of paternity applies when the married parents are still together at the time of the child's birth, as well as:

search
When a child is born within 300 days of the termination of marriage between the child's mother and ex-spouse
search
When an individual marries a child's mother and voluntarily asserts himself as the father on the birth certificate or vital record
search
When a man lives in the same home as the child for the first two years of the child's life and holds the child out as his own

Unless there's a court adjudication or the presumed father completes a Denial of Paternity (DOP) form and the child's actual biological father signs an acknowledgment of paternity (AOP) form, the presumed father will retain all rights and responsibilities that come with legal paternity.

Texas Rules for Establishing Paternity Between Unmarried Couples

When a child is born out of wedlock in Texas, steps must be taken to establish legal paternity. Until they are, the child has no legal father. The Uniform Parentage Act, established under Texas Family Code Chapter 160, provides two primary ways for unmarried couples to establish paternity. The first is for both to sign an Acknowledgment of Paternity (AOP) form with the Vital Statistics Office. This has the same effect as a court order establishing paternity. In Brownsville, the vital statistics office is located on the first floor of City Plaza, located at 1034 E Levee Street, Brownsville, TX 78520. Filing the AOP form requires a $6 processing fee. Both parents must be present and provide valid identification for notarization.

Denying Paternity in Texas

According to attorneys at the Brownsville-based Law Office of Cerise Reyna de Garduno, the Texas Family Code allows the courts to terminate a parent-child relationship in the case of mistaken paternity. If a man has been ordered to pay child support but does not believe he is the child's biological father, he can file a petition asking the courts to terminate the relationship. If the courts find that the man meets the legal requirements, they will order both the man and the child to submit to DNA testing. If the test results show that the man is not the child's biological father, the courts may terminate the relationship and the support obligation.
