Boundaries Act 1721

Where mears crooked,

Boundaries may, with consent of tenant and immediate owner in reversion in writing, &c. be made streight and in more convenient places,

and the lands exchanged on each side,

reversioner must be seised at least for life, remainder in tail to his sons.

Where the lands unequal in value, there may be a perpetual rent-charge on the greater proportion, to go as the land ought.

Exchanged lands, to same uses.

V. And whereas the bounds and mears between lands do often run in crooked lines, and sometimes through places inconvenient for making of such ditches or fences as aforesaid, and it would be most convenient for the occupiers and proprietors of such neighbouring lands to make the fence between them in a streight line, and to exchange the lands left out on one side of such streight line for the lands of equal value, worth, and purchase, took in on the other side thereof; which may happen to be impraticable for want of a sufficient estate in the proprietors of such neighbouring lands, or one of them, to make such exchange: be it therefore enacted by the authority aforesaid, That in such cases the persons, whose lands are so contiguous and to be bounded by a fence between them as aforesaid, may, and they are hereby impowered and enabled, by consent of the tenant or tenants of such lands, and the immediate owner and proprietor thereof in reversion expectant on the lease then in being, appearing by writing under hand and seal attested by three credible witnesses at least, to make the boundaries in streight lines in more convenient places, and to exchange the lands on one side of such streight line or fence for the lands of equal value, worth, and purchase on the other side of such right lines; so as such reversioner be seized of the lands, which he shall so grant in exchange, at the least for term of his own life, with remainder limitted over to the sons of his body begotten in tail male; and if it shall happen that the lands, left on one side of such streight line or fence, shall be of a greater value, worth, and purchase, than the lands took in on the other side thereof, then and in such case the proprietor, to whom the greater proportion shall fall, shall be enabled to charge the same with a perpetual rent-charge sufficient to countervail such difference or disproportion; which rent-charge shall go to such person and persons, and for such estate and estates, and to and for the same uses, as the land so charged ought to have gone; and the lands received in exchange shall go to such person and persons, and for such estate and estates, and to and for the same uses, as the lands given in exchange ought to have gone, in case no such exchange had been made.
