Local authorities play a vital role in protecting children and making decisions that shape their future. When concerns about a child’s welfare lead to care proceedings, professionals are often required to assess complex family circumstances within tight timescales, while balancing the child’s best interests with the legal duty to explore appropriate family placements. In many cases, establishing biological relationships is not straightforward. Families are increasingly diverse, records may be incomplete, and key individuals may be absent, deceased or unwilling to participate in proceedings.
When uncertainty exists around family relationships, legal DNA testing can provide objective biological evidence that supports informed decision-making and helps cases progress with greater confidence.
The challenges facing local authorities
Local authorities are expected to explore whether a child can be cared for safely within their wider family network before long-term alternative care arrangements are made. However, the family structures encountered in care proceedings are rarely simple. Social workers and local authority teams may be presented with extended families involving half-siblings, grandparents, aunts, uncles and other relatives, all of whom could play an important role in a child’s future.
Before a placement can be fully assessed, it is often necessary to establish if a biological relationship exists. While family accounts are important in these cases, they may not always provide the certainty required to support legal proceedings. In these situations, DNA testing forms one part of the wider evidence base, helping professionals verify family relationships where questions remain unsolved.
When biological relationships need to be confirmed
Under the Children Act 1989, local authorities have a duty to consider whether a child can safely remain with their wider family network before alternative care arrangements are pursued. Kinship care can offer children greater stability, continuity and the opportunity to maintain important family connections.
Difficulties often arise when local authorities are assessing potential kinship carers or supporting applications for Child Arrangements Orders or Special Guardianship Orders, particularly where the biological relationship between a child and the proposed carer cannot be easily demonstrated. This may occur in in instances where parents are be absent or deceased, paternity is disputed, relatives have had limited previous involvement in the child’s life or documentation is limited. Delays or uncertainty in establishing family relationships can have significant consequences. One such consequence is sibling separation, with an estimated 37% of children in care living apart from at least one sibling.
Legal DNA testing can help establish these relationships, providing evidence that supports further assessment of suitable family members and enabling care planning to progress without unnecessary uncertainty.
How legal DNA testing supports decision making
Legal DNA testing provides biological evidence that can support decision-making at key stages of care proceedings. By helping to confirm family relationships where documentation or family accounts are inconclusive, it enables local authorities to progress assessments with greater certainty.
Depending on the circumstances, testing may be used to:
- identify potential kinship carers when a parent is unavailable for testing
- confirm grandparent, avuncular or sibling relationships
- support assessments for Special Guardianship Orders or Child Arrangements Orders
- resolve disputed parentage where biological relationships are central to care planning
- provide evidence suitable for use within family court proceedings.
Selecting the appropriate test is essential, as every family situation is unique.
Choosing the appropriate DNA test
While parentage testing remains the most familiar form of DNA analysis (confirming paternity or maternity), he most appropriate testing approach depends on the circumstances of each case.
Where parentage needs to be established before birth, NorthGene™ also offers non-invasive prenatal paternity testing. Available from as early as 8 weeks into pregnancy, non-invasive prenatal paternity testing enables biological parentage to be confirmed safely before birth, supporting earlier assessments for kinship care, parental responsibility and family court proceedings.
However, it is not always possible to confirm these relationships where a potential parent is unavailable or unable to participate in proceedings. In these circumstances, alternative relationship tests can help establish biological links between a child and members of their extended family. Depending on the circumstances, this may include:
- Grandparentage testing to establish a biological relationship through the maternal or paternal line when a parent is unavailable for testing.
- Avuncular testing to determine whether an individual is the biological aunt or uncle of a child.
- Siblingship testing to establish whether individuals share one or both biological parents.
Because these relationships involve less shared DNA than direct parentage testing, it is essential to ensure the results are interpreted accurately. Working with a Ministry of Justice approved and UKAS accredited laboratory, like NorthGene™, gives local authorities confidence that testing is carried out to recognised legal standards and that the resulting reports are suitable for use throughout family proceedings.
We also offer non-invasive prenatal paternity testing, allowing families and local authorities to onfirm parentage early and support early assessments for kinship care, parental responsibility or family court, from as early as 8 weeks into pregnancy.
Providing evidence that meets legal standards
For local authorities, the quality of the evidence is just as important as the result itself. DNA test results presented during family proceedings must be collected and processed in accordance with recognised legal standards to ensure its integrity and admissibility.
As a Ministry of Justice approved and UKAS accredited laboratory, NorthGene™ carries out legal DNA testing under strict chain of custody procedures. Samples are collected by our network of independent third party sample collectors, identities are verified and every stage of the testing process is carefully documented. This provides local authorities, social workers and legal teams with the confidence that the resulting report can be relied upon throughout are proceedings.

Supporting better outcomes for children
Legal DNA testing does not replace professional judgement, instead, it provides reliable evidence that supports the work already being carried out by social workers, legal professionals and the courts.
By helping to resolve uncertainty around family relationships, DNA testing can strengthen kinship assessments, support timely decision making and ensure that potential family carers are not overlooked. Whether by identifying suitable relatives or resolving disputed family relationships accurate biological evidence supports decisions that prioritise children’s welfare while helping proceedings to move forward with greater confidence.
