Legal Sibling DNA Testing
Court ordered sibling DNA testing.
Verify your relationship with your family
A Legal Sibling DNA Test is used to determine whether two siblings share a parent when more direct methods such as a Paternity or Maternity DNA Test are not available.
The sibling DNA test uses statistical analysis to compare the DNA of potential siblings. This DNA test can have three possible conclusions: Full Sibling, Half-sibling, and Unrelated. These are based on percentages or sibling-ship indexes.
We always include the known parent in the testing process, especially when testing for legal reasons. Her DNA will speed up the testing process in our laboratory and increase the accuracy of the results.
Not including the known parent can lead to an inconclusive result.
If both siblings are male and are looking to discover if they share the same biological father we recommend a Legal Paternal Lineage Test, as it is more accurate.
Legal Sibling DNA tests require that everyone involved have their DNA collected by an impartial third party. This can be done 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, and adding a name to a Birth Certificate are common reasons for a Legal SiblingDNA Test
*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.

Steps For A Legal Sibling Test
STEP 1: ORDER YOUR Legal Sibling 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 3rd party will take responsibility for collecting the samples, verifying the identity of the participants, and returning the samples to our lab. This can be done anywhere, such as the third parties house, a medical 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.
Detailed instructions can be found here.
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 DNA 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.
