Our partnership

Our legal advisory services and tax planning are provided by the ADVISES partnership of lawyers, auditors and tax advisors. In the fields of audit services and tax compliance we act through RSM Altavis GmbH Wirtschaftsprüfungsgesellschaft, Steuerberaungsgesellschaft as a member company of RSM International.



ADVISES stands for integrated advisory services in the fields of legal advice, tax structuring and financial consulting. The solution of legal, business and tax issues regularly requires a comprehensive approach. With a view to the commercial goals of our clients we therefore render our advisory services on an integrated basis with a high demand to our professional skills.


Entrepreneurs for Businesses

In the eyes of our clients, ADVISES is first and foremost embodied in the form of our partners and employees. ADVISES demands and fosters commercial thinking and actions from its employees and thereby ensures that we are entrepreneurs for businesses. We do not see the solution of legal and tax issues as an end in itself. It is the commercial aims of our clients, on which we are focused.


Mergers, Acquisitions and Corporate Restructuring

Advisory services in the field of mergers and acquisitions are a core competence of our team. With the benefit of many years’ experience, first class references and deep know-how, we advise not only in the field of company acquisitions.Advice tailored to the relevant particular needs also enables the fast and successful completion of complex corporate projects.


Many of our clients operate internationally and therefore also seek our advice on cross-border matters. By virtue of our active role in the NOMOS Lawyers International and RSM International networks, we can also offer our clients high quality integrated services across borders. All of our employees speak fluent English.
