My home sits at the end of a driveway shared by 2 other homes. All three homes were foreclosures and to our collective knowledge, no surveys exist. Additionally, no use and maintenance agreement currently exists for the drive. While I do not foresee issues with getting the neighbors to agree to the "access/use" portion of the agreement I worry that the neighbor who uses the smallest portion of the drive may push back on shared maintenance. Before chatting with my neighbors further, I would like to better understand the law around whether any one neighbor can "opt out" of such an agreement. Also, I would very much appreciate the best arguments for *why* such an agreement is actually in the best legal interest of all of us.
