You may get a letter (sometimes called a notice) from HM Land Registry if someone applies to register a change that affects your property, for example if your neighbour wants to add a right of way that crosses part of your garden.
In some cases the application will be about historical rights, including:
mine and mineral rights - the rights to mines and their contents underneath your property
chancel rights - the requirement for you to contribute to local church repairs
manorial rights - the rights of the lord of a manor to the land surrounding the manor
