(a) In all cases where two (2) or more fence or no-fence districts adjoin at one (1) or more points, it shall be unnecessary for the districts to construct or maintain a boundary fence at the points where the districts adjoin each other. The terms "fence district" and "no-fence district" shall mean any territory within which the running at large of stock or animals of any kind is prohibited, regardless of whether it is termed a fence district, a no-fence district, a stock law district, or any other name.
(b) In all such cases, all of the provisions of the law under which each of the adjoining districts is operating shall be applicable to the districts, despite the fact that there is no boundary fence at the point where the districts adjoin.
