He is routinely instructed in matters with an international element and usually cases involving allegations of dishonesty, sharp practice or breach of trust. As well as conducting contentious work which has its genesis in investigations undertaken by the SFO, FCA, CMA and NCA, he has considerable experience in cross-border investigations, corporate and internal investigations. In addition, he maintains a busy advisory practice, providing opinions on ABC, AML, export controls and economic sanctions.

Oliver’s practice has always had a strong emphasis on Asset Forfeiture and the Proceeds of Crime, appearing for the Crown, defence, third parties and receivers. He has advised and acted for a variety of enforcement agencies (CPS, HMRC, UKBA, SFO & NCA), local councils, receivers and liquidators, both in the Crown Court and different divisions of the High Court. His experience has included undertaking work under all three confiscation regimes (DTA 1994, CJA 1988 & POCA 2002).

Oliver has a particular expertise in acting for receivers, third parties, companies, liquidators, administrators and those applying for compensation and release of monies from restraint, receivership and confiscation orders and those caught up with civil recovery of the proceeds of crime (KitallidesBark & Co v KhanSFO v Bates (‘Operation Anderson’).

Oliver is regularly invited to speak at ABC, AML and asset recovery conferences.
