in England". Allodium, meaning "land exempt from feudal duties", is first attested in English-language texts in the 11th-century Domesday Book, but was borrowed from Old Low Franconian *allōd, meaning "full property", and attested in Latin as e.g., , , in the Salic law (c. A.D. 507–596) and other Germanic laws. The word is a compound of *all "whole, full" and *ōd "estate, property" (cf. Old Saxon ōd, Old English ead, Old Norse auðr). Allodial tenure seems to have been common throughout northern Europe, but is now unknown in common law jurisdictions apart from the United States, Scotland and the Isle of Man. An allod could be converted into a fief, by the owner surrendering it to a lord and receiving it back as a fief. Allodial land title is common in the Isle of Man which has laws with Nordic origins. A version called udal tenure exists in the Orkney and Shetland Islands, also of Nordic origin. These are the only parts of the United Kingdom where allodial title exists, with the few exceptions. One such exception is the Scottish Barony of the Bachuil, which is not of feudal origin like other baronies but is allodial in that it predates (A.D. 562) Scotland itself and the feudal system, dating from the Gaelic Kingdom of Dál Riata. In recognition as allodial Barons par le Grâce de Dieu not barons by a feudal crown grant, the Baron of the Bachuil has the only coat of arms in Scotland granted a cap of maintenance with a "vair" (squirrel fur) lining (as opposed to ermine) by the Lord Lyon Court. Another exception is Somerset House which was vested in His Majesty explicitly not in fee simple, and is held to be allodial. Development of equitable title As late as the Tudor period, in order to avoid estate taxes, a legal loophole was exploited where land was willed to a trustee for the use of the beneficiary. However, trustees often abused this privilege, and heirs found that the courts of common law would refuse to recognize the "use" clause, and would instead grant title in law to the trustee. However, the courts of equity, which were developed by the sovereign to deal with obvious injustices in the common law courts, ruled that the heirs were entitled to the use of the property, and gave them title in equity.
