FEU, in Scotland, the common mode of land tenure. The word is the Scots variant of "fee" (q.v.). The feudal system still dominates Scots conveyancing, but its forms are now extensively modified by the Titles to Land (Consolidation) (Scotland) Act 1868, the Conveyancing (Scotland) Act 1874, the Conveyancing (Scotland) Act 1924, and some other statutes. It now contains three variants of holding. Burgage holding is the system by which land in royal burghs is held. Blench holding is by a nom inal payment, as of a penny Scots to be rendered upon demand only. In feu holding proper there is a substantial annual payment in money in return for the enjoyment of the land. The Crown is the first overlord or superior, and land is held of it by Crown vassals, but they in their turn may "feu" their land, as it is called, to others who become their vassals, whilst they themselves be come mediate overlords or superiors. This process of sub-infeuda tion may be repeated to an indefinite extent, except in cases where sub-infeudation has been conventionally prohibited prior to 1874. If the vassal does not pay the annual feu-duty for two years, the superior, among other remedies, may obtain by legal process a decree of irritancy, whereupon tinsel or forfeiture of the feu follows. Casualties, which are a feature of land held in feu, are additional payments to the superior, contingent on the happening of certain events. By the Feudal Casualties (Scotland) Act 1914 all such casualties as may not have been redeemed or commuted by Jan. r, 193o, shall be extinguished and discharged.
