Mark Twomey QC

Silk 2017 | Joint Head of Chambers

About

Described by clients as “at the top of the tree” Mark is a new silk who handles difficult cases producing “lucid, measured and informed legal comment which induce total confidence”. Lawyers appreciate his “pellucid, cutting-edge legal thought”.

Chambers and Partners say that Mark is “Incredibly intelligent and brilliant in an understated way as he has it all carefully figured out. He’s very analytical and he will fight fiercely for the client even when you know all the odds are against you.”

Mark’s client-focused approach separates him from other silks. A charming and subtle advocate who delivers excellent client care, Mark has a genuine interest in his clients and works tirelessly to advance the best possible case for them. He has a reputation for being a trusted advocate – both to solicitors and judges – and for providing insightful and carefully analysed arguments. His approachable and calm advocacy style suits his clients in public child law and has enabled him to gain the trust of those clients he represents who are in the most difficult of personal situations.

Experience

Mark handles both public and private children law work including care and adoption issues, as well as finance matter such as TOLATA. Mark also advises local authorities and claimants in relation to Human Rights Act claims, particularly those involving Section 20.

Mark comes from a background in mixed common law and has specialized solely in family law for the last 12 years, before being appointed QC in 2017. His practice includes the most complex of cases, including those involving severe injuries, international movement of children and abduction, and BIIR. He regularly appears at all levels of court, including the Supreme Court and Court of Appeal, on landmark cases that become leading authorities in their areas.

His recent cases include:

  • A High Court case, pursuing grave findings on behalf of one of the two applicant Local Authorities, involving three parents and three guardians in a case relating to incest, sexual abuse and international child trafficking
  • Child trafficking in care proceedings, looking at conflict before child trafficking regulations and the obligations arising under BIIR, and the issue of habitual residence
  • A BIIR case, addressing the correct approach to applications made under Article 15 and involving the issue of international adoption rights in the UK, in particular the adoption of foreign nationals—do UK courts have the right to order the adoption of the children of foreign nationals against the parents’ wishes?
  • Cases of inflicted or accidental injuries, most recently one involving the poisoning of a child by salt
  • The correct approach, decided on appeal, to be taken to assessments of parents under section 38 [6] Children Act 1989
  • A Court of Appeal case relating to the Possession Order made following domestic violence in the family home

Mark is a leader in the field of family law, holding high level appointments in the family law community and frequently delivering training or commentary on contemporary issues in Adoption, Contempt of Court, BIIR and Abduction, including to the Local Government Lawyers Association, the ALC, to solicitors and within Chambers. He is interviewed regularly by the BBC in relation to legal issues concerning children.
