We have gathered the most common questions our clients ask. Do not see your question?

Get in touch
  • 01 Do You Represent Businesses as Outside General Counsel?

  • 02 What Should I Expect During a High-Net-Worth Divorce in Illinois?

    Complex asset division, business valuations and tax consequences usually take the lead. We map the full financial picture first, then build a strategy around what matters most to you.

  • 03 How Do You Handle Cross-Border Matters Between Poland and the US?

    We work in both legal systems and coordinate with local counsel where needed, so company formation, contracts and succession questions are handled on both sides at once.

  • 04 Will I Always Be Able to Reach Someone at Your Firm?

    During business hours the phone is answered by a person, not a queue. You also know exactly which attorney is handling your matter.

  • 05 Do You Offer Initial Consultations?

    Yes. The first conversation is about understanding your situation and telling you honestly whether and how we can help.
