Time matters for owners in California. A severed interest left unused for 20 years can be terminated and returned to the surface owner under Cal. Civ. Code 883.210 to 883.270.
Quick answer: In California, a severed mineral interest is not permanent: it can revert to the surface owner if it goes unused. California lets a surface owner terminate a dormant mineral right after 20 years with no production, no taxes paid on it, and no recording, unless the owner records a notice of intent to preserve. The governing statute is Cal. Civ. Code 883.210 to 883.270. To keep it alive, record a notice of intent to preserve, or use the interest within 20 years (Cal. Civ. Code 883.220 and 883.230). If you may sell, confirm the clock has been met first.
A severed interest left idle for 20 years in California risks reverting to the surface owner under Cal. Civ. Code 883.210 to 883.270. As of June 2026.
California lets a surface owner terminate a dormant mineral right after 20 years with no production, no taxes paid on it, and no recording, unless the owner records a notice of intent to preserve. After 20 years of silence, no use, no lease, no production, no recorded filing, the surface owner can step in to clear the interest.
California scores 84 out of 100 on the Dormancy Risk Score and ranks number 2 of 51 for how easily an absent owner can lose a severed interest.
California treats the interest as dormant only if, for 20 years, there was no production or operations affecting the minerals, no separate property tax was assessed and paid, and no instrument creating, reserving, or transferring the interest was recorded. Under Cal. Civ. Code 883.230 the owner may record a notice of intent to preserve at any time, and may even record a late notice during a termination action by paying the surface owner litigation costs.
Enter the date the interest was last used, such as a sale, lease, recorded filing, drilling permit, or production, to see when it could lapse and exactly what resets the clock.

California has not enacted dedicated surface protection, so negotiated lease terms do most of the work if development disturbs the surface.
