The development of trust law in Victorian England, which led to many of the rules of equity still in force today, followed a social and economic evolution where the typical settlors were no longer members of the landed gentry but professionals and businessmen living in the cities and settling movable wealth, mainly financial assets, rather than landed estates. A similar development is taking place in the first decades of the twenty-first century, where the typical settlors are successful business people from various areas of the world, whose background is not the Anglo-American legal system and who have often accumulated an impressive wealth by running their own business. Their families may have interests in various parts of the world and succession planning is required in order to hand over the business to the next generation.
