Claire McKenzie is a highly qualified family law attorney with a unique background that distinguishes her from her peers. Few attorneys possess her credentials, including being a Certified Public Accountant (CPA), a former tax manager for one of the largest international accounting firms, and a former senior trial attorney for the U.S. Department of the Treasury, where she represented the Internal Revenue Service.
This extensive knowledge base is invaluable in cases involving significant assets and complex business structures, which often require the expertise of multiple financial professionals. With Claire's expertise in valuation, unreported and underreported income, and forensic accounting, clients can reduce the time and costs of hiring outside experts. She has a reputation for noticing details others may overlook, understanding the best course of action, and achieving favorable outcomes for her clients.
As a senior partner at Schiller DuCanto & Fleck, Claire handles complex family law litigation, including asset identification and valuation, pre-and post-marital agreements, child custody and visitation, property division, and spousal and child support. She is frequently sought after for her financial and tax advice and often co-counsels on cases due to her ability to thoroughly analyze financial statements and their associated details. Claire is recognized for her meticulous attention to detail, identifying key issues early on, and formulating effective strategies for her clients. Despite her extensive qualifications, she remains compassionate, approachable, and warm, creating a special connection with clients during difficult times.
Claire has served as the former Chairman of the Tax Committee of the Chicago Bar Association and is a member of the American Institute of Certified Public Accountants, the Illinois Society of Certified Public Accountants, the Chicago Bar Association, and the American Bar Association. She also serves as a Trustee for Maine Township.

"There are many possible issues in high asset divorce, but financial matters are usually at the heart of a case. Keeping an eye on the economics is a natural way of thinking for me – and it's often a huge benefit for my family law and divorce clients."

Client Reviews
- "I needed the BEST divorce attorneys and was referred to Meighan Harmon. Claire McKenzie also joined the team. It took almost 3 years, cost almost 2 million dollars BECAUSE, my ex tried to play games, not release the assets when the divorce was finalized, lied under oath and a whole list of things he pulled because he left me and then, a month later, I HAD to file for a divorce. I am doing fine, with Claire McKenzie’s persistence and Meighan’s stunning performance in court. However, we were billed and I ended up splitting the cost of the entire divorce. You get what you pay for. Any less expensive law firm, I believe, could not have performed at this level. This was August 2012 until November 2014. Assets were not released until six months later, May 2015, which was what drove the fees through the roof! I am quite happy with the results."
