Allodial title, a system in which real property is owned absolutely free and clear of any superior landlord or sovereign. True allodial title is rare, with most property ownership in the common law world (Australia, Canada, Ireland, New Zealand, United Kingdom, United States) being in fee simple. Allodial title is inalienable, in that it may be conveyed, devised, gifted, or mortgaged by the owner, but it may not be distressed and restrained for collection of taxes or private debts, or condemned (eminent domain) by the government.
