i had a bit of trouble what you said becuase it was not very clear. What I think you asked though is whether the village claim area has to cover the personal claim fully to revoke it. All that needs to happen is the village claim needs to cover the little pole with the skull that marks the claim. Then you can revoke it.
Not even that. You just need to stand on a tile where village claim and personal claim overlap and you can revoke the claim (you have to click the claim pole, so you must see it too).
I wish personal claim decayed... This village I found that looks as if no one plays anymore (left 3 runestones.. still no reply.) and I was going to break a gate down and go inside, but they have it claimed off.. the ENTIRE village, has to be at least 200kLP or so to claim the area.. its bigger then 3minimaps >:x
