It shall be the duty of all owners of land whose lands lie outside or abuts or lies adjacent to the boundary of the corporate limits of any town or city, to separate said land from adjoining lands by a partition fence to be constructed upon the line or lines dividing or separating said lands whether said lands were divided heretofore or may hereafter be divided. This only applies to a fence that separates two (2) adjoining parcels of property when at least one (1) of the adjoining parcels is agricultural land.

If any landowner fails to build, rebuild or repair such fence after receiving notice as provided for by law, the township trustees wherein said land or line is located, shall build, rebuild or repair such fence in a manner as provided for by law.
