Soo Yeon Lee is a partner at Mauck & Baker, LLC, a law firm located in downtown Chicago. She concentrates her practice in the areas of tax, business, real estate, and trust and estate law. A better way to describe her practice is that Soo Yeon Lee focuses on the areas of law that are of recurring importance to business owners and modern families. In order to be an even better attorney, she has sought out expertise in different areas of law across a wide range of legal and business boundaries over the course of her legal career. She now works with creative, entrepreneurial, and successful clients in a complex and ever-changing marketplace. 

A Trusted Advisor and a Zealous Advocate for her clients, with integrity and skillfulness, is what she strives to be. 


Within many of Soo Yeon Lee's practice areas there is an aspect involving tax. This layer is present in every transaction: whether it be a major business transaction or an individual's everyday real estate transaction or estate plan. She has acquired the requisite knowledge across different tax areas as well as different substantive areas of law (real estate and trust and estate law). This makes her truly unique and rare counsel. She regularly counsels on the tax aspect of real estate, tax planning for business transactions, estate and gift tax, non-profit tax counsel (real estate tax and sales tax exemption), private foundation, and charitable giving. This is the culmination of her practice, which is the product of her many years of vast experience and wide expertise, reserved for clients who understand and appreciate the unique value she provides.  


Soo Yeon Lee began her legal career as a litigator. She analyzes disputes accurately and assesses the risks involved, which is so critical in the early stages of any dispute. Given that she has handled hundreds of cases encompassing a wide range of issues and facts, she thoroughly understands the complex anatomy of a case in dispute. This ability of risk assessment and deep knowledge as to how a dispute would play out makes her a well-informed and thoughtful litigator, finding the unexpected support necessary to craft a strong legal position. 


Real Estate

In any business, real estate--whether owned or leased--is one of the most important and most valuable assets. She is especially passionate about real estate because real estate is critical to the success of a business or any non-profit and their ability to deliver on its mission. From choosing the right ownership and title vesting, to various management issues, tax strategies, and ultimate disposition, she provides comprehensive representation for the interests of her clients and skilled counsel in negotiating and conducting transactions in regard to many matters involving real estate.


Outside General Counsel for Business

The more Soo Yeon worked with business owners, the broader range of business and legal issues she resolved. The issues range from selecting the right type of entity, to buying a business, to various operations, to employment practice, to intellectual property rights, and to ultimate sale or disposition of the business. As a consequence, she began acting as outside general counsel for many businesses. Clients stay with Soo Yeon for years because they value the dependable, consistent, and solid business counsel through business ups and downs, recessions, and various crises. She gets to know her clients and thinks proactively for them. 

Trust and Estate

All of Soo Yeon's clients have one thing in common: the non-negotiable need to provide for their families and preserve their legacy of hard work. Thus, what started as the real estate component of estate planning for her clients became a fully integrated trust and estate practice. Soo Yeon Lee has a specialized knowledge in tax law that is relevant to her clientele. In this manner, she serves as the "family office" for her clients as she believes the concept of a "family office" is not reserved to high net worth individuals or families, but can be adapted to benefit average but successful and growing families. Furthermore, her ability to seamlessly communicate in both English and Korean makes her a top choice for multi-generational and multi-cultural families with ties to Korea. 

Korean-American Legal Hybrid

With her skills as a native speaker and first-hand experience of the Korean culture, Soo Yeon Lee is highly sought after as an advisor and advocate in the Chicago Korean business community. She provides legal services to many Korean businesses concerning everything from their day-to-day operation to litigation. She also bridges the US-Korean gap for her multi-cultural clients. The countries have very different legal systems which require seamless calibrations to simultaneously navigate. She wants to serve people like her; people with family in South Korea and the U.S. who encounter the same complexities that she has. Given her background and experiences in both countries, she can easily see the challenges and opportunities that others may not.

Bar Activities

Soo Yeon Lee is a very active member of Section of Real Property, Trust and Estate Law (RPTE) of American Bar Association (ABA). This ABA Section is one of the largest professional real estate, and trust and estate lawyers' organizations. She is a Section Council Member (2019-2022) and Associate Departmental Editor of the Probate and Property Magazine, after wearing a variety of leadership hats since 2012. 

Beyond her usual areas of practice, Soo Yeon Lee is committed to public service through extensive community involvement. She is currently serving on the Board of Directors for Age Options, a not-for-profit organization that advocates, plans, coordinates, and funds services in all suburban Cook County, Illinois. She is also committed to pro bono work in, among others, the areas of consumer credit and insolvency issues, foreclosure, landlord/tenant law, guardianship and small claims. From 2009-2015, she served as a member of the Board of Directors for Korean American Community Services (now Hana Center), a not-for-profit organization dedicated to offering educational, legal, health and social services for the local community in Chicago. She also served as the Director of Pro Bono Legal Clinic of the Korean American Bar Association of Chicago (KABA) from 2008 to 2012 and was an arbitration panelist in the Circuit Court of Cook County for several years.
