Onyoja specialises in family law and is developing a practice in international child abduction cases. She appears in proceedings concerning cross-border disputes and has represented parents in the UK and abroad in Hague Convention cases, Brussels II Revised and internal abductions.
Onyoja accepts instructions on a wide range of cases involving children in both private and public law proceedings at High Court and County Court level. She frequently appears in highly sensitive cases concerning domestic violence and child abuse, representing parents, local authorities and children, through their Children's Guardian. She also receives instructions in matrimonial finance disputes and injunction hearings under the Family Law Act 1996.
Onyoja has regularly given talks at seminars and in conferences on the 1980 Hague Convention with particular focus on the Article 13 (1)b) defence and the best interests of the child. She has been selected to speak at the 2017 Journal of Private International Law Conference, Rio de Janeiro, Brazil, with publication of her paper in the journal to follow. In academia, Onyoja has also delivered tutorials to undergraduates at the School of Law, University of Aberdeen.
