Take a look at the www.inversecondemnation.com blog for an outstanding list of myths about eminent domain that many lay folks believe, but which simply aren’t true. If your clients are facing the prospect of an imminent taking make sure they read it.
Though this list was written in the context of an impending referendum on whether to build a local rail line (which, if approved, will require many takings of privately owned land for the right-of-way in Hawaii), this is good advice in the context of imminent condemnation for any purpose, anywhere. Check out the post entitled Clearing Up Myths About Hawaii Eminent Domain Law and the Rail, dated November 2, 2008. Good stuff, that.
