We access our home by a privately owned road (through easements) shared by 15 owners. There is a bridge that is badly in need of repair. Half the owners are willing to share in the cost of the repair. The other half refuses. There is no road maintenance agreement. If the bridge fails, the only other access is by a circuitous poorly maintained road that would be difficult for emergency vehicles to use.
What legal remedy is there to make all owners pay a share in the cost?
