Remember that taking property includes more that just simple conveyance of title. You may have suffered a taking of property if the government builds a super highway or landfill next to your business property, thereby destroying its usefulness. Although it doesn't happen often, sometimes the government will exceed its authority and attempt to take property to be applied to some private business enterprise and not for public use. If the government is properly exercising its eminent domain authority, your property can be taken. The only question remaining is whether the price offered for your property equals its fair market value.
Many property owners litigate with the government to establish a fair price.
If you receive a notice that your property is to be taken by eminent domain, be sure to contact an attorney. It is almost always wise to reject the government's first offer, and at least threaten to litigate the matter of price. Also, consult with an attorney if the government does not directly take your property, but does something that destroys its value. You may be entitled to compensation. For example, you may be entitled to compensation, if the city puts in a landfill across the street from your restaurant.
