216.The five categories of interests set out in paragraphs 10 to 14 are of ancient origin, and of unusual character so that a buyer would not normally expect to see them. They can be very difficult to discover and can be exceptionally onerous. The overriding status of these rights will be phased out after ten years of this Schedule coming into force. The transitional period will give persons with such interests time to apply free of charge for their interest to be noted in the register. Franchises and manorial rights are the categories of interests most commonly found. Franchises originate in a royal grant, such as a right to hold a fair. Manorial rights are a very specific category of rights granted before 1926 and include a tenant’s right of common and a lord’s sporting rights. A Crown rent is a right to rent which was reserved to the Crown on the granting of a freehold estate, whether or not the right still belongs to the Crown. The right in respect of an embankment or sea or river wall is a liability falling on a person whose property fronts the sea or a river. It can arise in a number of ways, such as on grant or by custom. The only right to payment in lieu of tithe that still exists is a corn rent, although it is the rarest of all the categories listed and not all corn rents fall within it.
