Questions of considerable importance frequently arise as to the notice necessary to terminate tenancies of this character.
The principle of all tenancies of this kind is that something has been done by the party estopped, amounting to an admission which he cannot be allowed to contradict.
In uncertain tenancies there must be reasonable notice - i.e.
There were special privileges surrounding tenancies of these lands, such as freedom from tolls and duties, exemption from danegeld and amercement, from sitting on juries, &c. Hence, the phrase "ancient demesne" came to be applied to the tenure by which the lands were held.
The interesting point to be noticed is that, without any formal break, leasing land for life and for term of years is seen to be rapidly spreading from the end of the 13th century, and numberless small tenancies are created in the 14th century which break up the disposition of the holdings.
