In Idaho, a perfected water right (one that is licensed or decreed) is treated as real property that is appurtenant to the land it serves, meaning it generally transfers with a conveyance of that land unless the seller specifically reserves it (Idaho Code § 42-220; § 55-617). Because water rights can also be severed and sold separately, never assume — confirm in the purchase agreement and the title work exactly which water rights are included. Pending applications, permits, and transfer applications are treated differently (more like personal property) and must be assigned rather than passing automatically. After closing, the new owner files a Notice of Change in Water Right Ownership with the Idaho Department of Water Resources (IDWR). Water rights are a specialized area, so for property with irrigation, stock, or surface-water rights, Kootenai Title Company and, where needed, a water-rights attorney can help you verify what conveys.
