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 people being tested. 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 registering online and shipping the specimens to us.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible DNA testing service. 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. In order for the results of a DNA test to hold up in court, for child support, or to change the name on a birth certificate, the test must be done at a clinic using strict chain of custody procedures. Our Tustin DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Tustin, California - DNA Testing

Paternity Programs in Tustin, CA

In order for an unmarried Tustin father to gain parental rights and responsibilities over his child, as well as have his name placed on the birth certificate, he and the child's mother will need to properly establish paternity. Through the Orange County Parentage Opportunity Program (POP), both parents can sign a Voluntary Declaration of Parentage (VDOP) form to declare the biological father.

Because this is a completely voluntary process, it's crucial that a VDOP form is only completed once a paternity claim has been verified. In the event of any paternity uncertainty, both the mother and presumed father are recommended to first seek DNA testing services to accurately determine the biological father. Once confirmed, paternity can confidently be established to provide the father with parental rights as well as the ability for either parent to request child support services.

Rescinding a Declaration of Parentage in Tustin, CA

For instances where DNA testing was not used to confirm a paternity claim prior to signing a Declaration of Parentage form, a parent may learn later on that the presumed father is actually not the biological father. Having already signed the acknowledgment, the previously presumed father will still hold child support obligations, regardless of him now knowing he's not genetically related.

Through Orange County Child Support Services, a parent can submit a Declaration of Paternity Rescission Form up to 60 days after signing the original to have the paternity agreement removed. Demonstrating the importance of upfront DNA testing, the removal process becomes much more difficult and will likely require legal assistance to help make a claim in court after the 60-day mark.

Assistance Establishing Paternity in Tustin, CA

The paternity establishment process may not always be as simple as submitting a form. In instances where a parent declines to establish paternity on the belief of mistaken paternity or general refusal, paternity can then only be established using a court order. To do so, a parent must first file a petition to establish a parental relationship in Orange County Family Court.

Once a petition is filed, an Orange County judge can issue a summons to the opposing parent to complete the necessary steps to establish paternity. This most likely will include the use of DNA paternity testing to determine the child's biological father. Once paternity is established, the two parents may also move forward with child support, custody, and visitation agreements if necessary.
