Legally speaking how does a "shared drive" operate ? House we've looked at has drive passing through its land - the house is one side main garden the other - which is also access for a further property beyond the detached garage of the house. It is described as a shared drive, rather than the second property having a right of way over it, so wonder how the driveway land would be registered and arrangements regarding its maintenance would work (for example, cost to install lighting which would be of equal benefit).
