Under eminent domain and condemnation laws, the government may have the rights to take your property, pay you a fair value for it and use it for a project that is deemed necessary for the general good of the country.
You've received notice that your property is subject to condemnation, or eminent domain. That means a government agency wants to take your property for a public use, such as a road.
The government notifies you of its intent to take possession of your land to use for a government project. This is legal in some situations, using eminent domain laws.
