The South Angus Survival company and others advertise on the internet selling small pieces of land. The companies doing so often sell a doubtful title. The land in Caithness is of little value being mainly peaty bog areas. The ownership of a few centimetres of land entitles you to nothing in this country. I always advise anyone who wants to help the countryside to make a donation to the John Muir Trust http://www.jmt.org/ rather than buy a small piece of land to get certificate for their living room wall.
The titles handed out with some sales of land would be laughed at in this country and in fact there arre web sites dealing with the matters of purchased titles. The section on Fake Titles might give you some liinks http://www.caithness.org/links/faketitles.htm
Look at this web site and decide if you woudl trust it http://www.informedinvestor.ic24.net...Different.html
There must be something about the American and some European countries mind set as They seem to be targeted by the companies selling these small pieces of land. It is not yet illegal to sell tiny pieces of land but it seems very odd to us here in Caithness.
There is also the danger that the government might one day decide to sweep away all of the titles to small pieces of land as it would make planning to do anything with the area almost impossible if an area was owned by millions of tiny land owners.
It would be interesting to know why you would want to buy a few centimetres of land in Scotland. We never hear of such practices in other countries but perhaps it does go on.
