Legal vs. Non-Legal DNA Testing: What’s the Difference?
DNA Testing Insights | Beacon Specimen Collection Services
When you need a DNA test, one of the first decisions you may face is whether you need a legal DNA test or a non-legal DNA test.
Both types of testing can provide valuable information about biological relationships, but they are collected and documented differently. Choosing the right type from the beginning can save time, money, and the frustration of having to repeat the test later.
What Is a Non-Legal DNA Test?
A non-legal DNA test—sometimes called a peace-of-mind DNA test—is generally used when you want answers for personal knowledge rather than for a court or government proceeding.
For example, someone may choose non-legal testing to privately determine whether an alleged father is the biological father of a child or to better understand another family relationship.
Because the results are intended for personal information, the collection process does not require the same documented chain-of-custody procedures used for legal testing.
Non-legal testing may be appropriate when:
You simply want answers for yourself or your family.
The results will not be submitted to a court or government agency.
You do not anticipate needing the results for a legal proceeding.
What Makes a DNA Test “Legal”?
The difference isn't necessarily the DNA analysis itself. One of the most important differences is how the specimens are collected, identified, documented, and handled.
For a legal DNA test, strict procedures are followed to establish and document the identity of the individuals being tested and maintain the integrity of the specimens throughout the collection process.
This typically includes identity verification, documented specimen collection, required signatures and photographs when applicable, chain-of-custody documentation, and controlled handling and shipment of the specimens to the laboratory.
These safeguards create a documented connection between the individuals tested, the specimens collected, and the laboratory results.
When Might You Need Legal DNA Testing?
Legal DNA testing may be requested or required for matters involving:
Paternity and family law
DNA testing may help establish biological relationships in cases involving paternity, custody, child support, or other family-law matters.
Probate and inheritance matters
Testing may be used when establishing a biological relationship is relevant to an estate or inheritance matter.
Immigration DNA testing
In certain immigration cases, DNA testing may be requested to provide additional evidence of a claimed biological relationship. Immigration DNA testing has specific requirements and should be arranged according to the instructions applicable to the individual case.
Other legal proceedings
Attorneys or courts may request relationship testing when biological relationships are relevant to a legal matter.
DNA Testing Isn't Limited to Paternity
Paternity testing may be the most familiar form of relationship DNA testing, but it isn't the only option.
Depending on the circumstances, DNA testing can also help evaluate other biological relationships, including:
Grandparent relationships
Sibling relationships
Aunt/uncle relationships
Twin zygosity
Prenatal paternity
Immigration-related biological relationships
The appropriate test depends on which individuals are available for testing and what relationship needs to be established.
Should You Choose Legal Testing If You're Unsure?
If there is a reasonable possibility that you may eventually need the results for court, an attorney, immigration, or another official purpose, ask about legal testing before the specimens are collected.
A peace-of-mind test generally cannot simply be converted into a legal test afterward because the required identity verification and chain-of-custody procedures were not completed during the original collection.
That could mean paying for another test and completing another collection.
