Jack Sperber has been representing private owners and condemning entities in eminent domain proceedings for 25 years. He does this work around the country, and has been involved in more than 30 trials, numerous evidentiary hearings, and more than 20 appellate arguments.
He focuses primarily on:
  • Serving as national eminent domain counsel to clients with large real estate portfolios.
  • Representing property owners in complex, high-value condemnation litigation.
  • Representing energy and utility companies in corridor acquisitions and other large energy projects and in defending against municipalization and other condemnation attempts affecting their own property.

Condemnation Proceedings

Jack represents landowners, developers, tenants and other entities in all aspects of eminent domain proceedings. Although he primarily represents private owners facing condemnation, he also works with condemnors. He understands the objectives of both sides and can readily recognize and anticipate issues his clients may encounter.
He has counseled national clients on eminent domain issues in more than 25 states, ranging from Fortune 500 companies to individual property owners.

Corridor Acquisitions

Jack represents utilities and energy companies in the acquisition of utility corridors and right-of-way for electric transmission lines, oil and gas pipelines, water pipelines, and other large energy facilities. He counsels clients and manages projects from inception through acquisition of the final parcel — whether by voluntary agreement or through disputed condemnation proceedings ending in the appellate courts.
Jack also represents utilities facing the condemnation of their assets by governmental entities seeking to use the assets to form their own municipal utility, and in defending against other takings of their property.

Firm Leadership

Jack sits on both the firm’s management board and its executive committee.
