Legal Paternal Lineage DNA Test
Paternal lineage (Y-STR) DNA Testing
Accurate proof of your paternal lineage
Wanting to confirm a relationship with a possible male relative? The Y-STR Paternal Lineage DNA Test can show if there is a relation between two males.
The Paternal Lineage test only works on biological males. Due to the Y chromosome being hereditary and passed down from father to son relatively unchanged over time (females do not have a Y chromosome). This test is limiting in that it cannot pinpoint the exact relationship between the two males that are known to share a common paternal ancestor. It only determines whether two males share the same paternal Y-STR marker. However, the test is helpful in excluding certain males from an alleged biological relationship.
If you are trying to prove the specific paternal relationship of an alleged father and son, please see our Legal Paternity DNA Testing page.
A Legal DNA Test is most often needed when dealing with matter of the court, such as a court order or in the cases of child custody. The legal DNA testing is a very different process compared to home paternity testing. Legal DNA testing follows a strict chain of custody and sample collection procedure, as well as different shipping and handling methods than non-legal testing.
Legal Paternal Lineage DNA tests require that everyone involved have their DNA collected by an impartial third party. This can be done at home or at facilities such as a medical office, health clinic, a hospital. Legal DNA test samples can be collected by anyone who does not have a vested interest in the outcome of the tests.
Child Support, Adoption, Child Custody, Court Orders, adding a name to a Birth Certificate are common reasons for a Legal DNA tests.
*Immigration DNA Testing is a separate process than both Home and Legal DNA, both in approach and sample collection. For more information on Immigration DNA Testing see our US Immigration DNA Testing Page.

Step 1: Order Your DNA Test Online (Contact Us)
Order your DNA test like you would any other product online. Fill in your name, email, phone, shipping address.
For any DNA test to be considered Court Admissible it must be shipped to and handled only by an uninterested and unrelated 3rd party.

This can be done anywhere, such as the third parties house, a medical facility, or law office. This third party can be anyone, a lawyer, notary, family friend, doctor, nurse, or pastor. But most importantly it must be someone with no interest in the results of the test.

Step 2: Get your DNA Collected
Make sure to bring a federally recognized government ID, such as a drivers license, passport, or military ID. In the case of a child being tested, a valid certified birth certificate copy must be brought. These should be copied or photographed by the collector. You will also be required to have a picture taken by the collector (or elect to bring one with you) at the time of the collection. The collector will help you fill out the paperwork, sign, include all copies and pictures (hard-copies or send electronic copies to Info@ValidityGenetics with the order number attached), and certify that the collection has taken place according to legal standards.
Step 3: Receive your Legal Paternity Results
After providing the sample at the collection site, the DNA test kit will be mailed in a secure and traceable package to our accredited home laboratory in El Paso, Texas. The professional laboratory technicians will handle your genetic samples according to the exacting standards set forth by our laboratory partner in preparing and processing the samples. Testing will be complete within two business days, the results will be double checked and verified for 99.99% accuracy, and after being signed off by our PhD lab directors we will issue a legal document to you via your email.
