Adjoining landowners are owners of land with common boundaries, and have mutual rights, duties, and obligations related to their adjoining pieces of land.
In Arizona, adjoining landowners, also known as contiguous property owners, have certain rights and responsibilities concerning their shared property boundaries. These include maintaining boundary fences, managing shared resources like water, and not causing harm to the neighboring property. Arizona law, for instance, follows the doctrine of reasonable use regarding surface water, which affects how adjoining landowners may direct or use water on their land. Additionally, Arizona's 'spite fence' statute (A.R.S. § 33-211) prohibits a landowner from erecting a fence or structure out of malice that is intended to annoy or harm an adjoining landowner. Adjoining landowners also have the right to trim tree branches or roots that encroach onto their property from a neighbor's property, as long as it does not harm the health of the neighbor's tree. Disputes between adjoining landowners over boundaries or nuisances can be resolved through negotiation, mediation, or, if necessary, litigation. It is advisable for landowners to consult with an attorney to understand the full scope of their rights and obligations and to resolve any disputes that may arise.
