Certainty is the most valuable asset in legal cases. Whether you’re navigating the complex dynamics of family law or the details of inheritance disputes, DNA provides the definitive proof needed. It has become a critical tool in cases where relationships or identity are central to court proceedings. For legal professionals, it is fundamental to not only understand what legal DNA testing is, but also how to ensure its legal integrity and admissibility.
As a Ministry of Justice and ISO 17025 accredited laboratory with over 30 years of experience, NorthGene™ is your trusted partner. In this blog, we explore the essential knowledge and practical insights you need to confidently ensure the validity, reliability and legal compliance of DNA test results.
DNA in different types of legal matters
DNA testing has become an indispensable tool in resolving various legal disputes, having big impacts on case outcomes. While its applications are diverse, two areas stand out for their use of DNA testing:
Family law
DNA tests are paramount for resolving disputes concerning paternity, child custody and child maintenance. They are also essential in amending birth certificates and, most critically, for safeguarding the welfare of children in cases where they have removed from their home environment.
The confirmation of biological relationships through legal DNA testing has many implications for participants. For fathers, it can present opportunities for child contact and visitation, and for mothers, it can represent the first step in obtaining financial support. Moreover, establishing these relationships directly influences decisions surrounding guardianship, parental rights and responsibilities, with the child’s best interests in mind.
However, it is important to advise participants that a confirmed biological relationship does not automatically grant parental responsibility. The Children Act 1989 clearly details who is automatically granted it and how it can be acquired, such as through a Parental Responsibility Agreement or a Court order.
Inheritance and probate
DNA tests are also relevant in probate matters, enabling individuals to conclusively prove their biological relationship to a deceased person to establish their claim to an inheritance. In cases of intestacy or disputed wills, this can be decisive in resolving the issue and assist executors and administrators in fulfilling their duties accurately:
- Intestacy – where an individual dies without a valid will. In these cases, the Laws of Intestacy distribute inheritance based on biological relationships, to the deceased’s spouse and children. DNA testing is used in these cases to identify and confirm relationships where the claimant’s link to the deceased is challenged.
- Disputed wills – even with a will, challenges can still arise, particularly if an unknown relative comes forward to claim a share of the inheritance. DNA testing provides evidence to support or deny these claims.
Furthermore, the confirmation of biological relationships presents participants with new opportunities to discover and potentially reunite with family members.
Legal requirements
To ensure DNA test results are admissible in the UK court of law, legal professionals must be aware of various key requirements:
- Accreditation – when conduced for legal purposes, DNA tests must be carried out by laboratories accredited to ISO 17025. This UKAS accredited certification ensures that the laboratory adheres to the highest standards of quality, reliability and competence in its testing and analytical processes.
- Chain of custody – a strict chain of custody is paramount throughout the entire process – from sample collection to testing and analysis. This eliminates any risk of tampering or contamination and ensures that the samples are collected, handled and tested in a controlled environment.
- Consent – this must be obtained in order to proceed with the test. When testing the DNA of children, this consent must be provided by those with parental responsibility. This may be the mother, the father named on the birth certificate, or the social worker involved in the case. It is important to note that in cases where an individual does not consent to provide their DNA sample, this refusal cannot be used as evidence against them.
Common challenges
Several challenges can be encountered by legal professionals when working on a case that requires a DNA test. NorthGene™ is equipped to alleviate these hurdles:
- Choosing a reliable, accredited laboratory
One of the most common challenges that legal professionals face is choosing a testing provider that not only delivers accurate results but also adheres to the stringent legal requirements for court admissibility. NorthGene™ directly addresses this concern as a Ministry of Justice approved laboratory. Our services are designed to ensure the highest levels of accuracy, confidentiality and efficiency, providing reassurance that all tests completed to high standards within strict legal timelines.
- Providing the key information
To ensure an efficient process when registering a case with NorthGene™ for sample collection, some key details need to be provided:
- Where sample collection is expected to take place, such as the participant’s home, your offices or prison.
- Contact details for the participants so that sample collection can be arranged directly and efficiently.
- Clear details of those who are due to receive the results report, such as the solicitors representing each party in the case.
- Who is signing for the child if they are under the age of 16:
- If someone other than the mother is signing, we need proof of parental responsibility – for example, if the father is known and signing for the child, the birth certificate is sufficient.
- In cases where the child has been removed from the home, an Interim Care Order (ICO) and the contact details of the involved social worker signing consent are required.
- Ensuring data protection and confidentiality
Maintaining data protection and confidentiality is a crucial concern in sensitive legal cases involving DNA. At NorthGene™, we only communicate with the lead solicitor of the case. We do not share any case details with other solicitors who may be working with the participants unless they are explicitly listed as key contacts on the registration form. This approach ensures full confidentiality and adherence to legal and GDPR standards throughout the process. Our expert team is trained to uphold these principles at every stage.
Collecting DNA test samples
To ensure the integrity of the DNA samples, they must be collected by an independent, impartial third party, such as a GP, registered collector or social worker. This prevents any possibility of tampering or compromise and ensures that the results are legally admissible.
NorthGene™ streamlines this process and facilities all sample collection arrangements. We accommodate various locations for collection, including your legal offices, the participants’ homes or even secure facilities like prisons (in these instances, we need the Prison ID number). Once you register your case and specify the preferred sample collection location, our sample collectors will get in touch with the participant within one working day to schedule a convenient appointment.
Upon receipt of the samples at our Deeside-based laboratory, results are processed and issued the next working day. The report will only be issued to the individuals listed on your initial registration form. It is then the responsibility of these recipients to pass the results on to the participants, ensuring the highest level of privacy and confidentiality.
