How to inherit water rights in Chile: probate, the Registrar and the Public Water Registry

For many families in southern Chile, the water on the farm matters as much as the land itself. A parent had a well, shares in the canal or an old resolution granting so many liters per second, and everyone assumed it came with the land. When the parent dies, the children obtain the probate order (posesión efectiva), register the land and keep irrigating as always. Years later, when they try to sell or receive a letter from the DGA, they discover the water right is still in the parent's name, or was never registered in anyone's name.

A water use right can be inherited, but it has its own registry, a Registrar that may not be the same one as for the land, and a second registry at the General Directorate of Water (DGA). If nobody takes care of those steps, the inheritance of the water stays halfway done, and in some cases a deadline runs that ends with the loss of the right. This guide explains how to do it properly, in what order, and what changes depending on the state in which the deceased left the water.

Short answer: a water right passes to the heirs like any other asset in the estate, but to dispose of it they must record the probate order and the special inheritance registration in the Water Rights Registry of the Registrar where the intake or the well is located, and then report the change to the Public Water Registry. If the deceased's right was never registered, it must be registered before April 6, 2032, or it lapses.

Water is not inherited together with the land

Chile's Water Code treats a water use right as an asset separate from the land. It is transferred by public deed, possession of it is acquired by registration in a special registry kept by the Real Estate Registrar (Conservador de Bienes Raíces), and it can even be mortgaged on its own. So the fact that the heirs registered the farm in their names says nothing about the water: they are two assets and two separate registrations.

Inheritance is governed by the Civil Code, because the Water Code itself says so. And Article 114 of the Water Code requires recording in the Water Rights Registry the same acts that Article 688 of the Civil Code requires for an inherited property: the registration of the order granting probate, the special inheritance registrations and, later, the allocation made in the partition. Until those registrations exist, the heirs cannot dispose of the right: they cannot sell it or mortgage it.

Step 1: include the right in the probate

Everything starts with the probate order. If the deceased left no will, it is processed before the Civil Registry; if there is a will, before the court. We explain the procedure in our guide to posesión efectiva step by step. What matters here is that the water right must appear in the inventory of assets, just like the land, vehicles or bank accounts.

To include it properly you need its details: the resolution that granted it, if there is one, and the registration with the Registrar, with its page, number and year. If the family does not have them, they can be found at the Registrar and in the public registry published by the DGA, as we explain in our guide on how to check whether a property has registered water rights. A right left out of the inventory is not lost, but it forces you to amend or supplement the probate later, and that is time you can save.

Step 2: register with the right Registrar

This is where the most common mistake happens. The competent Registrar for water rights is not determined by where the land is, but by where the water is. Article 118 of the Water Code assigns it to the district where the intake of the main canal on the natural watercourse is located, and for groundwater to the district where the well is. If the farm irrigates from a canal that takes its water from a river several districts upstream, the inheritance of the right is registered with the Registrar of that other district, not the one for the property.

At that Registrar, the probate order is recorded and the special inheritance registration of the right is made in the name of all the heirs jointly. If the right is later allocated to one of them in the partition, that allocation is registered as well. When the Registrar objects to a registration, there are ways to challenge it; we cover them in our guide on what to do when the Registrar rejects a registration.

Step 3: report the change to the Public Water Registry

The Registrar gives possession of the right, but the DGA keeps its own registry, the Public Water Registry (Catastro Público de Aguas), and its regulations require changes of holder to be reported to it. This is not a minor step: a right that is not in the Public Water Registry cannot be the subject of any procedure before the DGA, and moving the point of extraction or transferring its exercise requires the final certificate from that registry.

There is also a deadline to keep in mind. Before April 6, 2032, the holder must have the receipt of the Public Water Registry record annotated in the margin of the registration with the Registrar. From that date on, the Registrar will not record the sale of the right without that annotation. For a family planning to sell the farm with its water in a few years, it is a requirement to meet beforehand.

When the deceased's right was never registered

This is more common than it seems. The deceased applied for the water decades ago, the authorities granted it by resolution and nobody took that resolution to the Registrar. The 2022 reform required those rights to be registered within a deadline, and Law 21.841, published on October 9, 2026, set it at April 6, 2032. If the right is not registered by then, it lapses automatically by operation of law. We explain this in detail in our guide on the 2032 deadline to register water rights.

In these cases the inheritance has a prior task: getting the right registered before that date. If the heirs take their time with the probate, with reaching an agreement or with finding the papers, the clock keeps running anyway. That is why we recommend reviewing the status of the water at the same time the probate starts, not afterward.

When the deceased used the water without title

Another common situation is the well or canal intake the deceased used for a lifetime without ever having a granted right. There is nothing to inherit at the Registrar, because the right does not exist yet. What exists is a use, and that use can be regularized before the DGA if it meets the requirements of the second transitory article of the Water Code: the water must have been in use when the Code came into force, with at least five years of uninterrupted use, without concealment or force and without acknowledging anyone else's ownership.

The law allows the use of predecessors in possession to be added, so the heirs can rely on the years in which the deceased used the water. But the application is only accepted until April 6, 2032. If the well only supplies drinking water and domestic subsistence uses for the household, it may not need a right at all; we explain this in our guide on wells without water rights.

Shares in a canal or water community

When water arrives through a canal run by a water community or a canal association, the deceased usually held shares in that organization. Those shares are also inherited and follow the same registration rules. It is also wise to inform the organization so it updates its register of members, because it is the organization that distributes the water, collects dues and calls meetings.

The reform requires each member to have an individual title registered. If the deceased did not have one, Law 21.841 opened a collective route: the organization can ask the DGA to regularize all users without an individual title who are up to date on their dues, with the approval of two thirds of the votes cast at a special meeting. For the heirs, keeping dues current is therefore a condition for using that route.

Selling the land, the water or both

Once the inheritance is registered, the heirs can sell. But the water and the land are still separate assets. Article 317 of the Water Code requires the deed for the sale of a property to state expressly whether it includes the water use rights, and if it does not, they are presumed not to be included. If the intention is to sell the farm with its water, the deed has to say so, with the registration details of the right. And if only the land is being sold, it is wise to make clear what happens to the water.

Something similar happens in the partition. If the farm is allocated to one of the heirs, it is advisable to allocate the water right to that heir expressly as well, so it does not remain jointly owned by everyone when the land has already gone to one person. We explain this in our guide to partition proceedings. And if the heirs live outside Chile, all of this can be done with a power of attorney; our guide to handling a Chilean inheritance from the United States explains how.

Frequently asked questions

Is there a deadline to register the inheritance of a water right?

The law does not set a specific deadline to register the inheritance of a right that was already registered in the deceased's name. But until it is registered, the heirs cannot dispose of it, and if the right is not in the DGA's Public Water Registry, it must be proven there before April 6, 2032. If the deceased's right was never registered, that registration must also happen before that date or the right lapses.

Can I sell the inherited land and keep the water?

Yes. They are separate assets and can be sold separately. What matters is that the deed states clearly what is being sold, because if it does not mention the water rights, the law presumes they are not included.

Which Registrar records the inheritance of the water?

The one for the district where the intake of the main canal on the natural watercourse is located, or where the well is if it is groundwater. It may be different from the Registrar where the land was registered.

What happens if the heirs cannot agree?

The right remains jointly owned by all of them, and any heir can request a partition. In the meantime, it is wise to at least register the inheritance and keep the canal dues current, so as not to miss deadlines or the chance of a collective regularization.
