Timely advice to avoid potential conflicts

Finding solutions and concluding agreements

Solutions on friendly terms do always prevail

Well-timed advice offers a lot of opportunities to avoid potential conflicts in the future as well as the opportunity to discuss and find most convenient solutions and proceedings for such potential conflicts in prior of being raised. We may represent and advise you in all legal matters such as negotiations with business partners, banks, insurances, potential opponents and in family law and employment law matters. Jointly with you, we are looking for mutual agreements. If such solutions may not be found and, if  litigation proceedings are inevitable, we may represent you at the court in accordance with your chances.

Trust is the basis for a successful cooperation. Therefore, our major approach for all legal support is the very close cooperation with you and in accordance with your personal and economical aims.

We represent and provide advice to private individuals, undertakings of all kind and independent professionals.

We may keep all correspondence in English or French, if required.
