Which of the following has been the main cause of land grant disputes over time?
a. more than one government made land grants in new mexico.
b. spanish land grants did not establish clear boundaries.
c. people do not understand the laws relating to land grants.
d. more than one person wishes to control the same piece of land.

The correct answer is D) more that one person wishes to control the same piece of land.

The statement that describes the cause of land grant disputes over time is more that one person wishes to control the same piece of land.

One of the main reasons men and nations are confronted is the dispute of land. Before and after the Industrial Revolution, people were disputing portions of land to be farmed. Others did not want their property to be divided. The issue is that more that one person wishes to control the same piece of land. Many times the government has to intervene in order to dictate a resolution to the various disputes about land. So land grants can be divided into three: Private Grants, Community Grants, and Hybrid Community Grants.
