Feuhold (leasehold) was abolished in Scotland c20 years - but in practice it was nothing like English leasehold and most of them had lapsed anyway.
In principle it meant that you might to pay a few pounds per year to the feudal superior (iirc, the amount had been frozen years before). A few rogue people bought old feuholds and then tried to charge the "vassal" for changes to the "burden". The terminology is indeed archane: the superior, the vassal, the burden.
The title deeds of our house state some of the title conditions, which the superior had imposed, like (from memory) no mining (as the mineral rights belonged to the superior), no soap works, tannery, keeping of hens or cows, glue works..... 
All the houses built had to be different - although some only have minor differences, or were a mirror image of one further down the street. Before the houses were built, a double skinned wall for the back garden had to be built, in order to define the plot.
It's now a leafy conservation area and we have to get permission even to do tree surgery (let alone take down) on trees with a trunk with a diameter of more than 7.5cm
