The Land Registration Act of 2002 says that, in certain circumstances, the person who owns certain overriding interests (such as manorial rights and chancel repair) may potentially lose them unless they are protected through registration at Land Registry before 13 October 2013. After that date they may potentially be lost if the surface land is subsequently sold without being made subject to them. One of the effects of these changes has been that the Church Commissioners have embarked on a programme of research, registration and protection at the Land Registry. This programme does not create any new rights or interests but is confined to researching and then properly registering and protecting rights they believe are theirs. You can object to the registration if you believe you have grounds to do so. An example of a valid objection would be if you could prove that the right or interest no longer existed, or had been transferred to you.
