Property law (2022): Related topics: Lateral and subjacent support + Assignment


Season 17 Episode 46


Lateral and subjacent support, in the law of property, describes the right a landowner has to have that land physically supported in its natural state by both adjoining land and underground structures. If a neighbor's excavation or 

excessive extraction of underground liquid deposits (crude oil or aquifers) causes subsidence, such as by causing the landowner's land to cave in, the neighbor will be subject to strict liability in a tort action. The neighbor will also be strictly liable for damage to buildings on the landowner's property if the landowner can show that the weight of the buildings did not contribute to the collapse of the land. If the landowner is unable to make such a showing, the neighbor must be shown to have been negligent in order for the landowner to recover damages.

If the landowner owns everything beneath the ground on his property, he may convey to another party the rights to mineral deposits under the land and other things requiring excavation, such as easements for buried conduits or for water wells. However, such a conveyance requires the recipient to prevent any damage to the surface of the land caused by the excavation unless the conveyance itself grants express authority for the surface land to be damaged, "as reasonably necessary" for the recipient to exercise his extraction rights.

An assignment is a legal term used in the context of the law of contract and of property. In both instances, assignment is the process whereby a person, the assignor, transfers rights or benefits to another, the assignee. An assignment may not transfer a duty, burden or detriment without the express agreement of the assignee. The right or benefit being assigned may be a gift (such as a waiver) or it may be paid for with a contractual consideration such as money.

The rights may be vested or contingent, and may include an equitable interest. Mortgages and loans are relatively straightforward and amenable to assignment. An assignor may assign rights, such as a mortgage note issued by a third party borrower, and this would require the latter to make repayments to the assignee.

A related concept of assignment is novation wherein, by agreement with all parties, one contracting party is replaced by a new party. While novation requires the consent of all parties, assignment needs no consent from other non-assigning parties. However, in the case of assignment, the consent of the non-assigning party may be required by a contractual provision.
