How to Do a Paternity Test When the Father and Child Live in Different States
You do not need to live in the same home, city, or state to complete a paternity DNA test.
A multiple-location paternity test allows the father and child to receive separate collection materials, collect their samples independently, and return them for laboratory testing without having to meet in person.
This type of testing may also be called long-distance DNA testing, a split DNA test kit, or a DNA test shipped to different addresses. The wording may vary, but the purpose is the same: making paternity testing possible when the participants live apart.
My Forever DNA® offers multiple-location testing for families who need a private, manageable way to complete relationship DNA testing across different homes, cities, states, or locations.
Key Takeaways
- The father and child do not need to live in the same state to complete a paternity DNA test.

When Do You Need a Multiple-Location Paternity Test?
A standard at-home paternity test works well when participants can collect their samples in the same household or coordinate collection easily.
A multiple-location paternity test is more useful when that is not practical.
Common situations include:
- The alleged father lives in one state and the child lives in another.
- Parents live in separate households.
- The father and child live in different cities.
- One participant lives far enough away that meeting in person would be difficult.
- Participants need collection materials sent to separate addresses.
- Work, travel, military service, or family circumstances make shared collection impractical.
- One participant is outside the United States and shipping arrangements need to be reviewed.
Distance does not prevent the laboratory from comparing the required DNA profiles.
The main difference is how the samples are collected and returned.
If everyone can collect samples at the same location, a standard at-home paternity DNA test may be the simpler option.
How Does a Paternity Test Work When Participants Live in Different States?
The process is designed so each participant can complete their part independently.
1. Choose the Correct Test
Start with the relationship you need to test and whether the results are for personal knowledge or official use.
For a standard father-child relationship test, choose a multiple-location paternity testing option.

2. Provide the Required Addresses
Separate collection materials can be prepared for the participants who need to test from different locations.
If your case involves several participants, international addresses, or another unusual situation, contact My Forever DNA® before ordering so the setup can be reviewed.
3. Each Participant Receives Their Collection Materials
Each participant receives the instructions and materials needed for their part of the test.
There is no need for the participants to meet or exchange samples with one another.
4. Each Person Collects Their Sample
Most standard paternity testing uses cheek swabs.
Each participant should follow the instructions included with their testing materials carefully, keep their sample correctly identified, and avoid mixing samples between participants.
5. Samples Are Returned Separately
Each participant returns their sample according to the instructions provided.
The samples do not need to be mailed on the same day.
Laboratory analysis can begin once all required samples for the case have been received and accepted for processing.
6. The Laboratory Performs the Relationship Analysis
Once the required DNA profiles are available, the laboratory compares the child's DNA with the alleged father's DNA to evaluate the biological father-child relationship.
The fact that the samples were collected in different states does not change the relationship being tested.
7. Results Are Delivered
After laboratory testing and review are complete, the results are provided according to the contact information and testing process associated with the order.
For a broader explanation of at-home DNA testing from collection through results, see How At-Home DNA Testing Works.
Do Both Participants Need to Collect Their Samples at the Same Time?
No.
One participant can collect and return a sample before the other participant is ready.
What matters is that all required samples eventually reach the laboratory and are accepted for processing before the relationship analysis can be completed.
This is one reason multiple-location testing works well for separated households and long-distance families. Participants can complete their collection independently without coordinating a single appointment or meeting.
Returning both samples promptly can still help prevent unnecessary delays.
What Comes With a Multiple-Location DNA Test?
The exact materials can vary depending on the relationship test and option selected.
Standard at-home collection generally includes the materials and instructions needed for cheek swab DNA collection and sample identification.
Because multiple-location testing involves separate participants, each person needs the information and collection materials required to complete their part of the case independently.
Rather than relying on a general article for exact kit contents, check the current product information for the test you are considering.

Is a Paternity Test From Different States as Accurate as a Standard Test?
Living in different states does not make the biological relationship harder for the laboratory to evaluate.
The participants' locations affect the collection logistics, not the biological relationship being tested.
Once usable DNA profiles from the required participants are available, the laboratory performs the relationship analysis associated with the selected test.
Important factors include:
- Correct sample collection
- Proper sample identification
- Avoiding contamination
- Returning all required samples
- Providing complete case information
- Informing the testing provider if possible fathers are close biological relatives

At-Home vs. Legal Paternity Testing Across State Lines
Multiple-location testing can be arranged for both personal and legal situations, but the process is different.
Informational At-Home Testing
A standard at-home multiple-location paternity test is generally intended for personal knowledge.
Participants collect their own samples privately from their respective locations.
This may be appropriate when you want:
- Personal relationship answers
- Peace of mind
- Private family clarity
- A convenient testing process without meeting in person
Because the participants collect their own samples, their identities and collection are not independently verified through a legal chain-of-custody process.
Legal Paternity Testing
If the results are needed for:
- Court proceedings
- Child support
- Custody
- Immigration
- Inheritance
- Birth certificate changes
- Another official requirement
you may need a legal DNA test with documented chain of custody.
Legal testing across different states can require coordinated verified collection procedures for each participant.
Do not complete a standard self-collected home test first if you already know that legally admissible results are required.
Can a DNA Test Be Shipped to Two Different Addresses?
Yes. That is one of the primary purposes of multiple-location DNA testing.
Separate collection materials can be sent to different addresses so each participant can complete their part of the test independently.
People may search for this using phrases such as:
- DNA test shipped to two addresses
- Split DNA test kit
- DNA test for people in different states
- Long-distance paternity test
- Paternity test when the father lives in another state
- DNA testing in two locations
These phrases generally describe the same testing need: the participants cannot conveniently collect their samples together.
Can the Father Live in Another State?
Yes.
A father can participate in a paternity test even if he lives in another state from the child.
The father collects his sample from his location, while the child's sample is collected separately.
Once the required samples are received for the same case, the laboratory can perform the paternity analysis.
This setup is common for:
- Separated parents
- Shared custody situations
- Long-distance families
- Adult children and fathers living in different states
- Families who cannot travel for testing
Does the Mother Need to Participate?
Many standard paternity tests can be completed using the child and alleged father's DNA without the mother's participation.
If the mother lives separately from the other participants, that alone does not prevent testing.
However, unusual family circumstances may affect which participants are recommended.
This is especially important when possible fathers are closely related to one another.
For more detail, read DNA Testing for Father and Child Only: How It Works Without the Mother.
Can Multiple-Location Testing Be Used for Other DNA Relationships?
Yes.
The same general collection format can also be useful when participants in other relationship DNA tests live apart.
Depending on the available testing option, this may include:
- Sibling DNA testing
- Grandparent DNA testing
- Maternity DNA testing
- Aunt or uncle DNA testing
- Other supported relationship DNA tests
The biological relationship determines which test should be ordered. Multiple-location collection simply addresses the fact that the required participants are in different places.
If you are unsure which relationship test applies to your situation, browse At-Home DNA Tests or contact My Forever DNA®.
What If One Participant Cannot Provide a Cheek Swab?
Multiple-location testing and alternative-sample testing solve two different problems.
Multiple-location testing is for situations where the participants can provide normal samples but live in different places.
Discreet or alternative-sample testing is for situations where one participant cannot provide a standard cheek swab and another approved DNA source may need to be considered.
Possible alternative samples can include personal items containing biological material, but viability varies.
If the issue is the sample rather than the distance between participants, read Alternative DNA Samples: What Can Be Used for DNA Testing?.
You can also explore Discreet DNA Testing.
What If One Participant Lives Outside the United States?
International situations can require additional planning because shipping availability, customs procedures, delivery time, and return logistics may vary by destination.
If one participant is outside the United States, contact My Forever DNA® before ordering so the available testing and shipping options can be reviewed for your specific locations.
How Long Does a Multiple-Location DNA Test Take?
The total timeline depends on more than laboratory processing.
It can be affected by:
- Shipping to each participant
- How quickly each person collects their sample
- Return shipping from each location
- When all required samples reach the laboratory
- Whether the samples are accepted for processing
- Whether another sample or additional testing is required
Because there are multiple participants and locations involved, the slowest part of the process may simply be waiting for every required sample to arrive.
Check the current product information for the most relevant turnaround estimate rather than relying on a fixed timeline in a general article.

Frequently Asked Questions About Paternity Testing in Different States
Can I do a paternity test if the father lives in another state?
Yes. Multiple-location paternity testing allows the father and child to collect their samples separately from different locations.
Do both participants need to collect their samples on the same day?
No. Each participant can complete their sample collection independently. Laboratory analysis generally waits until all required samples for the case have been received and accepted.
Can a DNA test kit be sent to two different addresses?
Yes. Separate collection materials can be sent to different addresses when participants live apart.
Is a long-distance paternity test less accurate?
The distance between participants does not change the biological relationship being analyzed. Accuracy depends on appropriate samples, correct collection, and laboratory analysis.
Can a paternity test be done across state lines for court?
Legal testing across different states may be possible, but it requires chain-of-custody procedures and verified collection. Arrange legal testing before collecting samples if the result is needed for an official purpose.
Does the mother need to test?
Many standard father-child paternity tests can be performed without the mother's participation. Tell the testing provider about any unusual family circumstances before ordering.
Can siblings or grandparents use multiple-location testing?
Multiple-location collection may also be available for supported sibling, grandparent, maternity, aunt or uncle, and other relationship DNA tests.
What if one participant cannot provide a cheek swab?
That may require an alternative-sample testing option rather than a standard multiple-location kit. Review the Alternative DNA Samples Guide.
What if one participant lives internationally?
Contact My Forever DNA® before ordering so shipping and testing logistics for the destination can be reviewed.
What if more than two people need kits sent to different locations?
Contact My Forever DNA® before ordering. The appropriate setup depends on the relationship test, number of participants, and addresses involved.
Start a Paternity Test From Different Locations
The father and child do not need to travel or meet in person simply because they live in different states.
A multiple-location paternity test allows each participant to complete collection from their own location and return their sample as part of the same relationship test.
If your situation involves different addresses, long-distance family members, or participants in separate states, start with the multiple-location testing options below.
