The third Article of the Statute establishes that all lands of the Grand Duchy of Lithuania will be eternally in the Grand Duchy of Lithuania and never enter as a part of other states. It allowed the right to own land within the Grand Duchy of Lithuania to only its own families. Anyone from outside the Duchy gaining rights to a property would actually own it only after swearing allegiance to the Grand Duke of Lithuania. These articles were aimed to defend the rights of the nobility of the Grand Duchy of Lithuania nobility against Polish, Prussian and other aristocracies of Polish–Lithuanian Commonwealth.
