Water and Water Rights

The answer depends entirely on what kind of water right is attached to the property, and the distinction matters more than most buyers expect.

If a property you are considering has a well, do not assume the water right comes with it just because the well is physically on the land. Confirm in writing, in the deed itself, that the water right is explicitly conveyed. If the deed is silent on it, get that addressed in writing before you close, not after.

New Mexico water law is specific about what happens when a water right changes hands, and it is stricter than most buyers expect. Under state law, NMSA 1978 § 72-1-2.1, a new owner must file a Change of Ownership form with the New Mexico Office of the State Engineer, using the form prescribed for that purpose (OSE Form WR-02), every time ownership of a declaration, permit, license, or adjudicated water right changes.

This is not paperwork you can skip or put off indefinitely. New Mexico's administrative code is explicit: the State Engineer will not accept a Change of Ownership form unless it comes with a copy of a recorded warranty deed or other instrument of conveyance showing the water right in the new owner's name. Once the OSE accepts the filing, the new owner also has to record a copy of that change-of-ownership form with the county clerk in the county where the water right is located. Skipping this step does not just create a paperwork gap. It means the State Engineer's own records, the official record of who owns what water right in New Mexico, will still show the previous owner, which can complicate everything from future sales to disputes over use.

An acequia is a community-run irrigation ditch, in many cases centuries old, introduced through Spanish colonial settlement and still governing water distribution across parts of Taos County today. If a property comes with acequia rights, you are not just gaining water access. You are becoming a parciante, a member of a governance structure with real legal obligations, not just a social expectation.

New Mexico's Acequia Act, NMSA 1978 Chapter 73, Article 2, gives each acequia's elected commissioners the authority to set assessments for maintenance, adopt bylaws, and enforce them. The mayordomo, the elected official who manages day-to-day water distribution, has real legal power behind that role: state law allows an acequia to suspend a parciante's water rights for failing to provide labor or pay assessments toward ditch maintenance, and a mayordomo can pursue a civil penalty in magistrate court against a member who fails to do either. Damaging the ditch or taking water against the mayordomo's order is treated as a criminal misdemeanor, prosecutable in magistrate court, with the possibility of an injunction on top of that.

In practice, this usually shows up as an annual community ditch cleaning that every parciante is expected to either show up for or pay an assessment in lieu of. Skipping it is not a minor faux pas. It is a real, enforceable obligation under New Mexico law, and a newcomer who treats it as optional is the fastest way to start a relationship with the neighbors on the wrong foot. Before buying a property with acequia rights, ask to see the specific acequia's bylaws, since obligations and assessment amounts vary by ditch, and confirm whether the property's membership status with that acequia is current.

A private well in Taos County almost always comes paired with a private septic system, and both are the homeowner's responsibility to maintain, not a utility's. Well water quality is not routinely regulated or tested the way municipal water is, so a water test before you close, checking at minimum for coliform bacteria, nitrates, and total dissolved solids, is worth doing even though nobody will require it of you. Budget for septic inspection and maintenance as a real, recurring cost of rural ownership, not a one-time item at closing.

A standard title search and title insurance policy is built around land ownership, and it typically does not extend the same assurance to water rights attached to that land. That gap matters in New Mexico specifically, where water and land are legally distinct kinds of property that happen to often travel together. If water rights are a meaningful part of why you are buying a particular property, raise this directly with your title company and ask exactly what is and is not covered, rather than assuming a clean title report on the land means the water right is equally secure.
