Dispute Resolution Law Firm in Austria


If you have a problem requiring legal action, our team can assist you in analysing risk, managing disputes and seeking constructive solutions in your best interests. CMS´s sector-focused lawyers are not just litigators or arbitration specialists but business-minded problem solvers. Using our global experience and local knowledge, we can safeguard your interests before state courts, arbitral tribunals and in alternative dispute resolution.

Dispute resolution law firm - in Europe and worldwide

We can handle your dispute across almost any European jurisdiction, obtain judicial assistance in foreign proceedings and deal with enforcement procedures for foreign judgements and arbitral awards.

If you want your dispute to stay out of court or arbitration, we can guide you tactically in achieving this. We routinely act in all business areas before state courts and as counsel in international and domestic arbitration proceedings. Our partners also regularly act as arbitrators.

A further risk you may face is the threat of an external investigation amid allegations of corporate wrongdoing. Our specialists can support you 24/7 through sensitive investigations by criminal and regulatory authorities, including negotiating settlements where appropriate.
