As for any territorial dispute the question you're asking is: will any of the people who've bought "moon estate" on this website be able to enforce the border (either individually or collectively)? Unless a superpower bought one of this estates, the answer is most likely no. I think those citing the "outer space treaty" and such are misled. The reason there's no private property on the moon right now is because there's absolutely no incentive to do so. If we start colonizing the moon, and in particular if we start mining it you can be sure that the story will be much more different. Look at the many territorial disputes around the arctic (and its valuable resources).
