Quick question... land law.

If the deed says "N's children's horses can graze" then I agree that is only a personal advantage

I think as a matter of general strategy, it's fine to say something like 'well, this probably isn't an easement for x,y, z reasons', but then go on to say 'but if that is wrong, the effect would be [that it binds the purchaser of the servient land, or whatever]', because then, if the examiner thinks you are wrong about the first part, you will still get marks for discussing the other aspects. Of course, you shouldn't do that if you are completely certain that the right is not an easement, because then you would be wasting time and effort on the next part of the discussion.

That would be amazing! Should I PM you?

Yes, PM me tomorrow at 3pm roughly (after my seminar) I'd be in a library and I'll forward them to you.
PM me your email address and the notes you need. I'll send them to you tomorrow. When I've sent them I'll send you a PM to let you know x
