What chain of custody protects
Chain of custody is an unbroken written trail showing who handled each sample, when, and how it was sealed. It protects every participant, because it makes it very difficult for anyone to question whose DNA was tested.

Service in Franklin, Tennessee
When a result needs to stand up in front of a court, an agency, or a records office, how the samples were collected matters as much as the science.
Overview
Legal paternity testing uses the same laboratory analysis as a private test, wrapped in a careful documentation process. Every participant shows identification, is photographed, and signs consent. A neutral collector seals the samples and records each handoff.
This record is what separates a legal result from a private one. Without it, a result generally cannot be relied on for official decisions. DNA Paternity Solutions explains each requirement up front so nothing comes as a surprise on collection day.

Some participants live in different places or cannot attend at the same time. Collections can often be arranged separately, as long as each one follows the same documented procedure.
Your attorney or the requesting agency decides how a result is used. The collection itself should simply follow the procedure that party expects.
