DNA Testing for Surrogacy Cases

by | Jan 27, 2026 | Legal & Immigration

Since the introduction of The Surrogacy Arrangements Act 1985, surrogacy has become an increasingly popular way for many people across the UK to start a family. In fact, the number of parents welcoming a new baby via surrogate has quadrupled in the last decade, with over 500 children per year born through surrogacy. However, the process doesn’t come without a critical legal step: confirming the genetic relationship between the intended parents and the child. That’s where legally admissible DNA testing for surrogacy purposes becomes essential.

Why is DNA testing for surrogacy done?

DNA testing in surrogacy cases confirms the biological link between the intended parents and the child born via surrogate.

Under UK law, the surrogate is initially considered to be the legal mother of the child. As such, a Parental Order is necessary to transfer the legal rights, responsibilities and parentage from the surrogate to the intended parents. This establishes them their legal rights and responsibilities as the child’s legal mother and father.

Since 2014, surrogacy arrangements have accounted for 47% of all parental order applications made to family courts.

Requirements for a Parental Order

The DNA test is a necessity when the application for a Parental Order is submitted, but is also particularly useful in simplifying and speeding up the process.

The application has certain legal requirements that must be met in order to list the intended parents as the child’s legal parents. These include:

  • The application must be made within 6 months of the child’s birth
  • The intended parents must have the child living with them
  • The child must have been carried by a gestational surrogate (rather than a traditional surrogate)
  • The intended parents must prove that at least of them are genetically related to the child. This is usually evidenced by results of the legal DNA test within the application

Furthermore, if a couple uses a surrogate in another country, they will need to prove a biological relationship to the child in order to bring them back to the UK, and demonstrate that they have a right to British citizenship and a British passport.

Ensuring the DNA test is admissible

Once you have confirmed the need for a Parental Order, the first step in obtaining a DNA test is choosing a provider whose results will be legally admissible and, therefore, accepted by family court.

This means that the laboratory performing the DNA test must be UKAS accredited and Ministry of Justice approved – like NorthGene™. These accreditations ensure that a full chain of custody is maintained throughout the testing process whilst adhering to the highest standards. This ensures that sample integrity, identity and security are guaranteed, preventing any challenges to the results in court.

To confirm a genetic relationship to the child, available tests are paternity or maternity, to confirm the biological father and/or mother of the child. Moreover, NorthGene™ offers legally admissible non-invasive prenatal paternity testing, so you can gain some clarity regarding paternity during the pregnancy.

Peace of Mind

While securing a Parental Order is the primary driver for legally admissible testing, DNA analysis also provides invaluable reassurance for the intended parents.

Gestational surrogacy is completed via IVF, transferring the embryo of the intended parents to the surrogate. While extremely rare, issues like sample misidentification or mix-ups can occur in the clinical setting. The DNA test acts as a safeguard, providing full peace of mind that the new baby is genetically related to the intended parents.
