We understand that international corporate or financial crime investigations are stressful experiences, whether you’re under investigation yourself or simply giving evidence. Our lawyers can advise and represent you if you’re already involved in an investigation or if you’re worried that you might be in the future.

International investigation or litigation can have a serious impact on your personal and professional lives. You may even face extradition. We’ll work to reduce the impact for you, your career, and your loved ones.

Our lawyers are highly experienced with these sensitive investigations and will always try to resolve your case as quickly and discreetly as possible.

For a confidential discussion, with no obligation, call us on 0370 1500 100, or send us an online enquiry and we’ll get back to you.

Sheffield conveyancers are simply the best!

Fast friendly and efficient service from Sheffield team all dealt with electronically due to distance with buying on south coast... The price quoted was fair, fixed and compared favourably against other large firms. Would definitely use again and recommend to anyone.
