Contracts
Customized Contracts Are Crucial for Success in the U.S. Market

Successful business operations in the United States require clear, well-drafted contracts that protect your interests and ensure compliance with U.S. laws. 

Improperly drafted or executed contracts and corporate documents can expose your business to serious legal and financial risks in the United States. Ambiguous terms, missing clauses, or non-compliance with U.S. federal and state laws may result in costly disputes, breach of contract claims, or even regulatory penalties.

Our Miami-based legal team assists European entrepreneurs, foreign investors, and international businesses with preparing, reviewing, and negotiating business agreements tailored to your specific needs.

Risks
The Risks of Using Your European Contracts Without Adapting Them to U.S. Law

For European entrepreneurs and foreign investors, these risks are even greater. Contracts drafted under European laws often fail to meet U.S. legal requirements and may not be enforceable in American courts. What works under German, French, or other European contract laws may be invalid or incomplete under U.S. state and federal regulations.

Additionally, direct translations of European contracts into English frequently lead to ambiguities, misinterpretations, and clauses that lose their intended meaning. These linguistic and legal mismatches can result in serious misunderstandings, unfavorable obligations, or even invalid agreements in the U.S.

To help control costs, we can often use your existing European contracts as a starting point - then tailor them to U.S. federal and state law so your agreements are clear, compliant, and enforceable in the U.S. market.

frequent asked questions
FAQs
Why Is It Important to Draft Customized Contracts Instead of Using Templates?

Generic contract templates often fail to address the specific needs of your business, the jurisdiction in which you operate, or the complexities of international transactions. For European entrepreneurs and foreign investors doing business in the U.S., this can create serious legal and financial risks.

Customized contracts are tailored to your business model, industry, and cross-border requirements, ensuring they comply with U.S. law, protect your interests, and reduce potential disputes. Working with an experienced U.S. business attorney ensures your agreements are clear, enforceable, and aligned with your goals.

How Does Working With a U.S. Business Lawyer Differ From Using a Company Registration Agency?

Unlike ordinary registration agencies that only handle basic filings and are not lawyers, our firm provides comprehensive legal supportfor starting, structuring, and managing your U.S. business. While an agency may submit your LLC or corporation registration, they typically don’t review your contracts, analyze tax implications, or ensure compliance with U.S. federal and state laws.

With us, you benefit from:

  • Strategic legal advice tailored to European entrepreneurs and foreign investors.

  • Entity selection guidance - helping you choose between an LLC, corporation, or alternative structures based on your business goals and tax considerations.

  • Custom contracts and documents instead of generic templates, ensuring enforceability and risk protection.

  • Post-formation legal support, including compliance monitoring, contract reviews, and ongoing guidance as your business grows.

In short, we don’t just register your company - we build a solid legal foundation to protect your investments and support your long-term success in the U.S. market.

How Do Governing Law and Jurisdiction Clauses Affect International Contracts?

For European companies and foreign investors, governing law and jurisdiction clauses are critical in U.S. contracts. They determine:

  • Which state’s laws will apply to the agreement.

  • Where disputes must be resolved — in the U.S., your home country, or via arbitration.

  • How enforceable your contract will be across different jurisdictions.

Choosing the wrong jurisdiction can lead to costly litigation or make enforcement abroad difficult. Our attorneys draft and negotiate contracts with cross-border enforceability in mind, ensuring your business interests are protected internationally.

What Should Foreign Investors Consider Before Signing a U.S. Business Contract?

Before entering into any U.S. business agreement, foreign investors should carefully review:

  • Governing law & jurisdiction - which state’s laws apply and where disputes will be resolved.

  • Liability & indemnity clauses - to avoid unexpected financial risks.

  • Termination conditions - ensuring clarity on when and how agreements can end.

  • Regulatory compliance - especially if contracts involve multi-state or international transactions.

Our Miami-based business attorneys specialize in helping European clients understand U.S. contract terms, negotiate favorable conditions, and reduce legal risks.

What types of companies do you work with?

We work with a wide range of clients, including European entrepreneurs, foreign investors, and international businesses seeking to establish or expand their presence in the United States. Our clients include:

  • Startups and small businesses opening their first LLC or corporation in the U.S.

  • Medium-sized companies expanding into Florida, Miami, or other U.S. markets.

  • International investors managing real estate holdings or forming investment entities.

  • Established corporations requiring ongoing support with contracts, compliance, and corporate governance.

Our goal is to provide tailored legal solutions that meet the needs of companies at every stage of growth - from formation to expansion and long-term operations.

What documents are most often required when starting a company in the US?

When forming a company in the United States, several key documents are typically required to establish your business and ensure legal compliance. These may include:

  • Articles of Organization (for LLCs) or Articles of Incorporation (for corporations) - officially registering your company with the state.

  • Operating Agreement (for LLCs) or Bylaws (for corporations) - defining ownership structure, management roles, and decision-making rules.

  • Employer Identification Number (EIN) - required by the IRS for tax purposes, hiring employees, and opening a U.S. bank account.

  • Shareholder Agreements - outlining the rights, obligations, and protections of company owners.

  • Business Licenses and Permits - depending on your state, industry, and location.

  • Registered Agent Appointment - a U.S.-based representative to receive official notices and legal documents on behalf of your company.

Obtaining an EB-2 NIW immigrant visa

I applied to Artem's agency to obtain an EB-2 NIW immigrant visa. I applied and have never regretted it. From the very beginning of our communication Artem and his team made the best impression on me. At all stages of the case preparation they provided maximum assistance in information gathering, collection and preparation of letters, advice, and everything in general. All communication was as open, friendly and prompt as possible.

I also got the impression that what they were doing was as interesting to them as possible. It is interesting to develop, interesting to solve non-standard problems, interesting to learn something new. With this approach, the potential of these guys is almost limitless, they have a great future, you can see it and it is very encouraging. I am very glad that I was lucky to find this agency.

Yes, I forgot to say, the result of the case submission was approval, and from the first time.

I wish the whole agency team and Artem personally to conquer new heights, success and prosperity, you are great guys!

I can only recommend Susanne as a lawyer. She provided us with advice and support and assisted us in establishing our business in Florida. Susanne did not just offer simple consultations but worked with us to develop solutions and established the necessary contacts for our business.

Leone Zhgun, P.A. was a true support for us in the process of obtaining the E2 Visa. Not only did they handle the documentary preparation and meticulous compilation of necessary documents, but their advice was also extremely professional. The entire team, led by Artem, assisted us with all our questions, and if we didn't understand something, Susanne was able to translate from English to German. We were also well-prepared for the upcoming interview at the embassy. I can only recommend the firm and look forward to continuing our collaboration.
