Legal & official testing

DNA evidence for
court and official use.

Legal DNA tests follow a documented chain of custody so the result can be relied on by family courts, the Child Maintenance Service, solicitors and local authorities in England & Wales. The laboratory analysis is the same as a peace-of-mind test. What changes is how the samples are collected and evidenced.


Why it stands up

What makes a result
court-admissible.

A court needs to be certain the samples came from the named people and were never interfered with. The legal route evidences every step, which is why a peace-of-mind result can never be upgraded to a legal one later.

Witnessed collection

Samples are taken by a trained, independent professional. No sample is collected unsupervised, so no one can question who provided it.

Verified identity

Every adult presents photo ID, which is checked and recorded at the appointment. Children are identified through a person with parental responsibility.

Documented chain of custody

Samples are sealed, signed and tracked from collection to the laboratory bench, with every transfer recorded.

Accredited analysis

Analysis is carried out by ISO 17025 accredited partner laboratories and reported in a format suitable for legal proceedings in England & Wales.

Common questions

Before you
instruct a test.

  • Who must consent? Every adult tested consents in writing at the appointment. For a child, consent must come from someone with parental responsibility. Testing never proceeds without it.
  • Where are samples collected? At our Dartford clinic or an arranged appointment convenient to the parties. Separate appointments can be arranged so parties never need to meet.
  • How long do results take? Results are ready within 3 to 5 working days of the laboratory receiving all valid samples, and are released only to the people and professionals you authorise.
  • Is a home kit ever acceptable for court? No. Unwitnessed samples cannot evidence who provided them, so peace-of-mind and home-kit results are for personal use only and cannot be upgraded later.
