Anyone who receives notice that their property is threatened by eminent domain action should consult with an attorney who is very experienced in eminent domain law. Unfortunately, too many people obtain poor results after failing to hire an eminent domain attorney.
One of the first things that Penn DOT will do when they approach a landowner in an eminent domain case is say that they, themselves, have commissioned an appraisal that has set the value of the property, and that the landowner should settle for that amount.
