Lawyer specializing in international commercial and business law

Your specialist lawyer for commercial law and business law

International trade law and international business law pervade all areas of economic life today. Many areas of business law and commercial law have already been standardized within the European Union. However, the laws can still differ from state to state, unless the law has been standardized. This must be taken into account when entering international trade. As an experienced lawyer and specialist lawyer for international business law, I support you, in particular with the following topics of international business and commercial law:

  • Drafting contracts when purchasing goods, components and services
  • Enforcement and defense of claims in the event of supply chain disruption
  • Enforcing and defending against price increases due to increased energy and material costs
  • Examination, negotiation and judicial enforcement of liability claims
  • Liability issues in the event of breaches of duty by managing directors
  • Contractual instruments for securing the purchase price
  • Design of distribution systems
  • Subcontracting Agreements
  • Confidentiality and secret protection agreements with contractual penalties
  • Non-compete agreements and customer protection agreements under European antitrust law

With my law firm, I cover the entire area of German contract law, including the German Civil Code and the law governing general terms and conditions, as well as international contract law. Every company that is active in cross-border trade should ensure that international commercial law is taken into account in every purchase contract or contract for work and services. As a specialist lawyer for international commercial law, I can include and apply the details of international commercial law when drafting a contract. My skills as a lawyer also include cross-border sales of branded products within the European Union, antitrust law, liability for defects and cross-border corporate law. Furthermore, as a lawyer, I can offer you individually tailored contracts and solutions for various industries and business areas.

Advising the CEO on contract negotiations

Clear contract design
I ensure that the contract is clear and that legal options are optimally used.

Whether your company sells your products or purchases goods, components or raw materials to manufacture your products, there are important legal areas to consider. Therefore, international contract law, international commercial law, defect rights, limitations of liability, infringement of third party rights such as trademark and patent rights, questions of insurance and coverage and the applicability of German law are always important topics for companies. As a lawyer, I regulate them clearly and sensibly in every contract. If conflicts arise, provisions in your international treaty should resolve them. As your lawyer, I will help you to formulate your respective contract, be it a purchase contract or a contract for work, internationally and securely in German and English. New developments and problem areas such as supply chain problems, increases in energy and material costs and securing purchase price claims must always be addressed

decision-making process

I support you in choosing the right place of jurisdiction.

Contract law covers preventive conflict situations. In the event that clarification is not possible, your contract should therefore also make a decision on the jurisdiction of a German court or international commercial jurisdiction. However, the legal requirements and the way the courts work differ from country to country. Not all countries offer equally fast and efficient legal protection in court. Sometimes arbitration can be a better choice for conflicts abroad. As your lawyer, I will support you competently in this decision-making process.

International contract law

Assistance with international contract law

International contract law has many facets. International private law determines which law applies. Your contract, be it B2B or e-commerce, should clearly state the applicable law. In international trade, you shouldn't leave anything to chance. UN sales law, also known as CISG, is automatically applied when choosing German law if it is not expressly excluded in the contract. With my law firm for international commercial law at your side, you can be sure that your company does not overlook any important points in contract negotiations and the assertion of claims.

International trade law also affects the law of general terms and conditions. The inclusion of your purchase or sale conditions and the rejection of the terms and conditions of your contractual partner can be decisive, for example in the case of obligations to examine the goods and complaints and retention of title in the European Union. Today, contract law is increasingly affecting international commercial contracts, especially in e-commerce and B2B platforms. As your lawyer, I am up to date and will reliably inform you about new legal regulations at home and abroad.

International Sale of Goods and Liability

Advice on the international purchase of goods and possible liability risks

As a specialist lawyer for commercial and corporate law and as a specialist lawyer for international commercial law, I have geared my commercial law firm to the international purchase of goods as well as advice and legal representation in liability risks. German sales law, UN sales law and contract law play a central role in my advice in order to correctly assess liability risks in the event of defects in products or maintenance services in international trade and to derive claims.

If you deliver your products to other companies in the European Union, securing your purchase price claim from your customers is of particular importance. As a preventive measure, as your lawyer, I set the right course for securing your legal position in contract negotiations in an international context. If a judicial enforcement of your claims abroad is necessary, you can fall back on my large international network of friendly law firms.

If you are unjustly sued, I will set up your legal defense strategy for you as a lawyer and explain the opportunities and possible risks to you. I will also give you legal advice on the delivery conditions according to Incoterms®, the international clauses in goods trading, cross-border sales and purchasing cooperations or serial damage to products and the associated recall.

If a managing director has made a mistake, I will advise you as a lawyer on enforcing or defending a claim, especially in negotiations with the D&O insurer.

Internationale Gründung

International foundation of sales companies

Depending on the sales structure and particularly depending on tax considerations, you should consider establishing sales companies in one or more EU countries. Questions of commercial law arise from the founding of a sales company through the processing of deliveries to modifications of your sales system.

When founding a company in another EU country as a sales company, it can be challenging to meet the different legal requirements. Failure to review and structure your project under commercial law can lead to delays or even failure. It is therefore advisable to consult an experienced specialist lawyer for international business law at an early stage in order to provide support in founding the company and structuring business relationships abroad.

As a specialist lawyer for international commercial law, I support companies in founding companies with international sales. I advise my clients comprehensively on legal issues and help them to draft commercial contracts that meet their needs and take all important legal aspects into account.

Firstly, the legal framework abroad should be thoroughly checked to ensure that you have all the necessary permits and licenses and comply with local and international laws and regulations. It is important to know the tax requirements of the country where the company will operate. As a specialist lawyer for commercial and corporate law, I work together with a network of tax specialists on questions relating to sales tax, corporation tax and trade tax law. As an experienced lawyer, I also check any contracts you enter into with suppliers, customers or business partners abroad to ensure that they comply with applicable laws and regulations. In addition, I advise my clients on setting up subsidiaries abroad and on reviewing joint venture agreements where necessary.

My experience in international commercial law and my extensive knowledge of the legal framework help me to meet the legal needs of my clients. As a certified specialist in commercial and corporate law and a certified specialist in international business law, I work closely with my clients to ensure their needs and goals are understood and met.
