About the official source
This is a statewide map, not a county site. NM Office of the State Engineer County Parcels 2025 layer (ArcGIS Map Viewer) covers parcels across New Mexico, and San Miguel County is one part of it. Because a state agency compiles this layer from local data, check with the San Miguel County assessor or recorder before relying on a recent change. As of our October 2026 test, anyone could open it without signing in or paying.

Before you rely on the lines
Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
