Criminal Defence
Our criminal defence team represents clients facing serious charges including murder, fraud, and terrorism. With decades of experience in high-profile cases, we provide robust legal representation from police station through to Crown Court trials. Our solicitors have successfully defended clients in complex cases involving Guantanamo Bay detentions and the Grenfell Tower Inquiry. We combine technical legal expertise with strategic advocacy to achieve the best possible outcomes for our clients.
Extradition
We specialise in extradition law, advising clients facing removal to countries across Europe and the United States. Our team handles cases from pre-arrest investigations through to High Court appeals, with a proven track record in negotiating settlements and representing clients at Westminster Magistrates Court. We provide urgent 24/7 support for extradition matters and have successfully challenged requests based on human rights grounds and proportionality arguments.
Sexual Offences
Our specialist solicitors defend clients accused of rape, sexual assault, and historic abuse allegations. We employ a meticulous approach to evidence analysis, including digital forensics and expert witness testimony, while maintaining sensitivity to the complex nature of these cases. The team has particular expertise in defending allegations involving vulnerable complainants and navigating the challenges of historic cases with limited contemporaneous evidence.
Proceeds of Crime Act
We advise on all aspects of confiscation proceedings under the Proceeds of Crime Act 2002, including restraint orders, enforcement proceedings, and applications for certificates of inadequacy. Our solicitors challenge asset seizures and represent clients in complex financial crime cases involving the Serious Fraud Office and HMRC. We have successfully negotiated reduced confiscation orders and secured variations to existing court orders.
Road Traffic Offences
Our motoring law specialists handle cases ranging from drink driving to totting-up disqualifications. Led by Mark Troman, the team provides local knowledge of London and South East road conditions while challenging penalty points and disqualifications through exceptional hardship arguments. We offer fixed-fee packages for guilty pleas and contested trials, with transparent pricing and clear guidance on sentencing options.
