    Successfully Prepare, Defend and Manage Large Appeals 03/20/2019 IAAO Webinar Series - While many assessors will routinely defend municipal assessments through an administrative appeal process or in court, there are certain properties that are, quite simply, different. At one point in her or his career, an assessor will be forced to mount a defense of such a massive assessment, coordinating with a team of municipal officials, legal counsel, and third-party experts.

    Through detailed discussion of real-life case studies, the presentation seeks to empower assessors to more fully understand the unique challenges involved in the "once in a career" abatement litigation. The goal of "preparing the mega case" is to help ensure that municipal assessors will be prepared to tackle those challenges head on and manage a team of professionals to ensure a successful defense.
