A business dispute often includes a broad range of issues, which can result in a variety of consequences. Whether you are the CEO of a large company or a small business owner in Chicago, you will likely run into issues that could result in legal problems on a regular basis.

Chicago, IL 60601

Some problems might never materialize fully, while others may end up in disputes. These problems include conflicts between shareholders and partners, competitors, counterparties, and even third-party employees.

When you face business disputes, it is crucial to make strategic and informed decisions to curb unnecessary costs as well as mitigate potential liabilities. The appropriate approach might change a dispute into a great opportunity. On the other hand, the wrong approach can damage a company’s entire operation.

Business Litigation Law Firm for Clients in Chicago and Throughout the USA

Oberheiden P.C. is a law firm that handles business litigation in Chicago and throughout the USA. We assist companies in protecting their best interests when they encounter legal problems. Our litigators possess extensive expertise in representing companies and industries in all kinds of disputes; they have many years of experience in handling settlement negotiations and matters in civil courts.

Oberheiden P.C.’s litigation team includes previous senior officials and investigators with several federal agencies, providing unmatched knowledge about the opportunities and risks presented by business disputes. By keeping our team entirely in-house, it is possible for us to effectively and efficiently develop and execute any litigation strategy to protect our clients.

Typical Business Dispute Types That Oberheiden P.C. Handles

While there are many unique factors in each individual case of business litigation, most disputes result from several primary issues. We represent business owners, businesses, and other related clients in lawsuits about:

1. Partnership Disputes

A dispute between limited liability company members (or LLC members) and partners is often disruptive and can even threaten the viability of the company. Such disputes need to be handled as soon as possible. A disagreement over financial management or a company’s direction can spill over into a business’s operations, leading to direct negative consequences for employees, customers, and clients.

When experiencing partnership disputes, businesses need to review partnership agreements. Does the agreement offer any resolutions? If the answer is no, then does the agreement specify any venues to seek a resolution? Does it offer ways that partners can protect their investments or the entire partnership? These key questions need to be answered before attempting to resolve the dispute informally.

It is often most helpful to everyone if the partnership dispute is resolved informally. This lowers costs and prevents the public from getting involved. In appropriate situations, Oberheiden P.C. works closely with clients to find common ground and leverage, then continues working diligently to obtain the best results without ending up in formal litigation. However, we are a business litigation law firm and will not hesitate to pursue claims in Chicago, in Illinois state court, or even federal district court if need be.

2. Shareholder Disputes

Similarly, a shareholder dispute presents a number of concerns and considerations. Due to the nature of corporate structure, these disputes may present extra complexities. We represent clients in disputes between individual shareholders, and we also handle shareholder derivative litigation that targets alleged wrongs by board members or corporate executives. Our lawyers’ expertise includes obtaining positive outcomes in disputes involving shareholders in both private and public companies. We have already achieved beneficial results in all federal and state trial litigation stages, alternative dispute resolutions, and informal negotiations.

3. Employment Disputes

When it comes to employee disputes, companies that want to obtain a favorable result must think about various practical and legal considerations. It is essential to determine the claims an employee has made against their company. Employees possess various rights under Illinois and federal law, so companies should take their time instead of rushing to judgments even if they think they understand the situation completely.

Oberheiden P.C. attorneys represent Chicago employers in all dispute types such as wrongful termination. Our attorneys handle litigation in federal and state court, and they will also take care of administrative proceedings before the Illinois Department of Labor as well as the Equal Opportunity Employment Commission (EEOC).

4. Customer Disputes

The challenges presented by disputes with clients and customers are unique. A company needs to protect its financial interests. However, the company must decide if it should look for ways to resolve the dispute amicably or if it should sue for damages. The answer may not be clear, which is why the right legal counsel can be beneficial for a business in this situation.

At Oberheiden P.C., we represent companies regarding all customer litigation types, whether they be disputes initiated by customers or the company. Our attorneys aid clients in making strategic decisions and take necessary legal actions to safeguard them. We ensure that our clients have all the information they may need to make the best decisions now and in the future.

5. Contract Breach

Contact breach claims can involve various issues, and both parties may possess grounds for alleging performance deficiencies. A disagreement over the applicability of a contract’s provisions, of the parties’ intentions, or contractual remedies and rights could end up in a legal dispute. It’s essential to develop a well-informed strategy even if the parties are mandated to use ADR. This strategy should be guided by thorough comprehension of the business and legal implications involved.

These might be the most prevalent business dispute types, but there are many other issues which might lead to litigation between businesses, competitors, and contracting parties. Other typical instances that could lead to business litigation are as follows:

  • Confidentiality breach
  • Franchise and antitrust disputes
  • Trade secret misappropriation
  • Fraud, including securities, consumer, and bank fraud
  • Intellectual property infringement
  • Disputes over business acquisitions and mergers
  • Non-solicitation and noncompetition covenants breach
  • Performance as well as payment obligation breach
  • Indemnity, representations, and warranties obligation breach
  • Tortious interferences with business opportunities and relationships

Even with these additional situations, the list of potential business litigation disputes goes on. Should you or your company experience any business dispute type in Chicago, we encourage you to contact Oberheiden P.C. Our attorneys will help you understand your options and implement effective strategies.
