This book goes over the set of laws and/or urban-territorial legal instruments of national scale produced in Bolivia since 1871, focusing on land property and its social role, which is the main study object of what is known as Urban Law. Through examining the urban legislation classified in five areas, this book first presents the existence of laws for intervening urban property between 1930 and 1950 and the following reluctance of the government to discuss this subject and its reconsideration in the decades of 1970 and 1980. Likewise, the article shows the permanent lack of urban legislation and the role of the state in urban matters after 1970, but also the permanent presence of the social role of property in the discussion over urban issues, at least until 1990.
