Boundaries and fences

Coterminous owners are mutually bound equally to maintain: 1. The boundaries and monuments between them. 2. The fences between them, unless one of them chooses to let his land lie open as a public common, in which case, if he afterwards encloses it, he must refund to the other a just proportion of the value, at that time, of any division fence made by the latter. R.L. 1910 Sec. 6645.
