Unmatched experience crafting the law through litigating and statutory drafting helps us develop unique approaches to complex matters.

At O'Keefe Lyons & Hynes, LLC, the approach is highly customized and not "off the shelf." Attorneys develop legal strategies based on extensive experience with property tax appeals, property tax litigation and tax planning. The strategies are always crafted according to each client's specific needs and changes in the property tax practice.

When the City of Chicago and Chicago Public Schools began to file underassessment complaints seeking assessment increases in the Board of Review and Property Tax Appeal Board and to intervene in taxpayers’ lawsuits in the Circuit Court, OLH did not simply defend market value. OLH is alone among property tax counsel in commissioning and copyrighting a comprehensive, county-wide Assessment-to-Sales Ratio Study by a University of Illinois economist and statistician to ensure that a uniform level of assessment be applied to market value. In certain cases, this proof has produced extraordinary settlements and tax refunds for clients.
