Frequently Asked Questions About Corporate Litigation in Illinois

  • Q: What types of disputes does a corporate litigation attorney handle?

    A: Corporate litigation encompasses a wide range of business disputes: breach of contract claims, partnership and shareholder disputes, trade secret misappropriation, business tort claims (fraud, tortious interference), non-compete enforcement, real estate disputes, and disputes between businesses and their vendors, customers, or competitors. Angelini & DiLeo Law represents business clients at every stage of litigation — from pre-suit demand letters and negotiation through trial and, if necessary, appellate proceedings.

  • Q: Can a business dispute be resolved without going to court?

    A: Many business disputes are resolved through negotiation, mediation, or arbitration — often faster and at significantly lower cost than courtroom litigation. Whether alternative dispute resolution is available depends on any arbitration clause in your contract, the nature of the dispute, and the opposing party's willingness to engage. Our attorneys evaluate all available resolution paths and recommend the approach most likely to achieve your business objectives efficiently, while remaining fully prepared to litigate aggressively if that is what the situation demands.

  • Q: My business partner and I are in a dispute. What are my options?

    A: Partner disputes can threaten the survival of the business itself if not addressed carefully. Your options depend on the terms of your partnership agreement, operating agreement, or shareholders' agreement — which is why having well-drafted governance documents matters so much. Resolution paths include negotiation, buyout of one partner's interest, mediation, or in severe cases, judicial dissolution. Our attorneys advise business owners in partner disputes from the earliest stages, working to protect the business and your interests while pursuing the most practical resolution.
