About David Josiah-Lake

David graduated with honours from the Guildford School of Law in 1990 before being admitted as a Solicitor in 1992, since which date he has specialised in all areas of family/relationship and children law – latterly concentrating primarily on the financial implications of living together whether as a married couple, civil partners or as unmarried cohabitants (and the financial and other consequences of relationship breakdown).

David’s reported cases

David was the lead Solicitor in the case of Re L [2008] EWHC 2149 (Fam). This case is the first and remains to date the only reported case concerning the posthumous retrieval and storage of gametes for use by a surviving partner in IVF treatment. The gametes were harvested following an interim order by Court (Mrs Justice Macur). Subsequent legal proceedings were brought by L against the Human Fertilisation and Embryology Authority (HFEA) and the Dept. of Health to enable her to access and to use the stored gametes in IVF treatment discussed but not yet underway at the time of her husband’s sudden and premature death. Whilst use of the gametes retrieved without consent in the UK is strictly prohibited, use of such gametes abroad is possible subject to the grant of a licence from the HFEA in this regard and this was the issue before Mr Justice Charles. The HFEA expressed concern about the case and David’s response can be found here https://www.bionews.org.uk/page_91660
