From the Wiki: >>Most property ownership in common law jurisdictions is fee simple. In the United States, the land is subject to eminent domain by federal, state and local government, and subject to the imposition of taxes by state and/or local governments, and there is thus no true allodial land. Some states within the U.S. (notably, Nevada and Texas) have provisions for considering land allodial under state law, and the term may be used in other circumstances.
