Judicial Warning & Naming 0f Serial Sperm Donor ‘Who Fathered 180 Children’

In a recently published family law case In the Matter of D [2023] EWFC 333, His Honour Judge Jonathan Furness KC took the unusual step to publicly name a serial sperm donor and warn the public and vulnerable women seeking to get pregnant of the dangers of unregulated private sperm donation. This followed a highly contested 2-year legal battle, described as a 'nightmare' and 'horror story', between a female same-sex couple and a prolific sperm donor who applied to court to be named on the child's birth certificate, obtain parental responsibility and contact with the child.

Genetic Testing: A Non-Biological Father, Mistaken Birth Registration & Parental Responsibility Void Ab Initio

The recent case of KL v BA [2025] EWHC 102 (Fam) brings into focus the complex legal issues that arose when genetic testing showed that a non-biological father was registered in error on a child's birth certificate. The central issue in the case was whether the effect of a declaration of non-parentage in respect of the non-biological father who had mistakenly been registered as the child's father rendered his acquisition of parental responsibility void ab initio (never having had any legal effect) or whether this could only be removed by court order.

Genetic Testing, Political Uncertainty & Citizenship: Family Law In Focus

As we start 2025, the evolving realities of direct-to-consumer DNA tests, political uncertainty and demand for foreign citizenship are increasingly calls to action. As people seek to understand and address these challenges it can create complex inter-related personal and legal questions. Such questions are increasingly drawing together and necessitating solutions that require specialist family law expertise. Successfully navigating a path through these choppy waters can require expert management and bespoke family law strategies to address the implications of genetic testing, legal and biological parentage, an application for a Declaration of Parentage and rectification of a birth certificate.

Posthumous Conception In Focus

The law governing posthumous conception in England and Wales sets out clear legal requirements designed to protect an individual's right to consent to the use of their eggs, sperm or embryos in treatment after their death. Eggs, sperm and embryos represent a special class of reproductive cells. They are very private and intimate, representing unique reproductive building blocks in human conception and an individual's genetic legacy. As such, the law is designed to prevent the unauthorised use of a person's gametes (or embryos comprising these) in treatment without their specific consent in life and after death. However, the prescriptive legal framework governing posthumous conception is not without its challenges in real life. What can be done to overcome these challenges?
