Legal vs. Personal DNA Testing: Which Do You Need?

The difference comes down to how the results will be used. A legal DNA test follows strict chain-of-custody procedures: sample collection includes identity verification of all parties and secure handling from collection to the laboratory. Those results may be submitted as evidence in court for matters like child support, custody disputes, or changes to a birth certificate.

A non-legal test is for personal peace of mind and doesn’t require chain-of-custody protocols, which makes the process simpler. In Michigan, unmarried parents can establish paternity either by voluntarily signing an Affidavit of Parentage or through a court order that may require a DNA test. Wayne County family court proceedings involving paternity, custody, or child support may require court-admissible results, so it’s worth confirming which type you need before your appointment.

What DNA Testing Is Used For

DNA testing covers a wide range of personal and legal needs. The most common use is confirming biological relationships, including paternity, maternity, siblingship, and grandparentage. Beyond relationship confirmation, DNA testing supports legal proceedings, assists with immigration documentation, and helps people explore their ancestry and genetic history.

Most DNA sample collections use a non-invasive cheek swab, sometimes called a buccal swab. In certain cases, alternative specimens such as hair follicles or fingernails may be used. Results for relationship DNA tests typically take several business days depending on the test type and laboratory processing.

What Makes a DNA Test Legally Admissible

Not every DNA test result can be used in court. For results to be used in Michigan family court proceedings involving child support, custody, or name changes on a birth certificate, the test must follow legal chain-of-custody protocols: identity verification of all parties at collection, standardized sample handling, and secure transfer to the laboratory. Our certified collectors follow these procedures, and when you need Court-Admissible DNA testing, we provide proper documentation so your results can be submitted where they’re needed.
