Corporate Representation & Corporate Defense

In recent years, companies in particular came more and more into the focus of law enforcement agencies and regulators. Companies operating on a national or international scale nowadays face an enormous increase in regulatory density and risks when doing business. That includes a large variety of business-related penal provisions as well as very strict tax and administrative obligations. The economic consequences directly caused by fines and levies, as well as the damage of the companies due to reputational damages or the exclusion from public tenders, can lead to severe financial consequences or even to an existential threat. An efficient risk minimization strongly requires tailor-made preventive advice and, in case of proceedings by law enforcement authorities or even dawn raids, the immediate involvement of an experienced economic defense lawyer as a corporate representative.

The corporate representation includes the base defense of the company to avoid fines or profit levies and in appropriate cases the internal investigation and of the facts. At the same time, Kanzlei Klengel advises on the enforcement of claims for damages or their efficient rejection and in appropriate cases assists the company in taking employment-related consequences.

In extensive proceedings, Juergen Klengel draws on a huge and well-developed national and international network of sophisticated inter- and extra-disciplinary colleagues. The law firm regularly works together with other excellent lawyers from other areas of law as well as accounting firms and tax consultants. If a parallel defense of organs or employees of the company is necessary, Kanzlei Klengel intervenes experienced defense attorneys from Frankfurt, Germany and other countries and ensures by this coordination a comprehensive and competent representation of the involved company and the individuals.

Based on his deep expertise and thorough approach, Juergen has led many internal investigations within companies on various criminal law matters. These matters were often multi-jurisdictional and related e.g. to international bribery, embezzlement or serious compliance breaches. Offering clear and pragmatic advice, Juergen also advises and represents clients seeking to recover assets lost due to criminal offenses.

The law Firm has also an extraordinary expertise and experience in the field of representation and defense in preliminary and criminal proceedings in which, in addition to the German authorities also foreign supervisory authorities or law enforcement agencies, such as the US Security and Exchange Commission (SEC), the US Department of Justice (DOJ), the UK Serious Fraud Office (SFO), the UK Financial Conduct Authority (FCA) or domestic and foreign tax authorities, are involved.

If the company has been harmed externally or by its own employees, the firm advises the management and the company on the strategic determination of the best course of action. This includes clarifying the facts and several important legal issues. Amongst other questions, it e.g. has to be decided with great care whether or not and at which point the enforcement authorities should be informed and involved actively.
