John J. Casey, JD, LLM

Mr. Casey began his practice concentrating in the areas of estate planning and estate administration, business transactions, and real estate. He later expanded those concentrations to include complex litigation under the False Claims Act.  Mr. Casey was part of a team that both filed and then prosecuted actions under the Illinois False Claims Act against internet retailers that failed to collect and remit use tax to the State of Illinois.  

After gaining valuable litigation experience, Mr. Casey joined a premier boutique estate planning firm located in Oak Brook, where he worked exclusively on estate planning and administration matters directly under the firm’s principal, a designated Fellow of the American College of Trust and Estate Council.  

Thereafter, Mr. Casey’s practice continued with a focus on trust and estate administration matters at Mayer Brown, LLP.  Mr. Casey prepared complex estate, gift, generation-skipping, fiduciary, and split-interest trust information returns, in addition to handling numerous estate administration matters for the firm. 

Mr. Casey’s experience in such litigation and estate planning and administration provides him valuable insight into strategies used to counsel clients before possible litigation, whether related to income, estate or gift tax matters, on behalf of trusts or estates (or in defense thereof), or in estate planning matters relating to the foregoing.

Mr. Casey obtained his Juris Doctor degree in 2006 and was admitted to the Illinois Bar in 2007.  He completed his Masters of Law in Taxation (LL.M.) at Chicago-Kent College of Law in 2014.

As a part of his course studies for this LL.M. degree, Mr. Casey received the CALI Excellence for the Future Award, as the highest scoring student enrolled in the law school Employee Benefit Plans course. 

Mr. Casey has participated as a speaker in presentations on estate planning, and trust and estate administration.
