This will yield numerous benefits for the users such as the time needed to access the data and make a registration will be reduced and the citizens will be able to see at one place the ownership structure of a real property and its location in space

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
