This bill establishes new procedures for the maintenance and cost-sharing of private roads held in common ownership by multiple landowners. It repeals and reenacts RSA 231:81-a, introducing definitions for key terms such as "private road," "maintenance," "equal," and "equitable." The bill clarifies the responsibilities of landowners regarding road upkeep, including requirements for written notice before maintenance work, emergency repair protocols, and the allocation of costs based on ownership and usage. It also specifies that roads governed solely by easement, deeded access, or license are excluded from these provisions.

Additionally, the bill outlines enforcement mechanisms for disputes over costs or maintenance responsibilities, allowing for mediation and court petitions for equitable relief. It prohibits any obstructions or signage within road boundaries without unanimous consent from all owners and establishes that no rights can be acquired through adverse use after the bill's effective date. The act is set to take effect on January 1, 2027, and includes a severability clause to ensure that if any provision is found invalid, the remaining provisions will still be enforceable.
