You do a land charges search. You do this via the land registry's online eservices website. You have to sign up. It costs a couple of pounds.
You do this for unregistered land.
Is the land registered? If so it will (should if land registry picked it up on first registration) be on the register of title.
Amy questions or queries?
Happy to assist further.
If the covenant was not registered then it is void
I state above how you check the land charges register at the land registry.
But it only applies to unregistered land. It has no relevance to registered land.
If the restrictive covenant was not registered on the register land charges it will be void.
I am just following up. Do you have any questions or queries? Hope I explained the position clearly, happy to assist further if necessary.
