Mineral Rights

Ask a Texas landman what mineral rights means and you'll get a straightforward answer. Ask a Louisiana one, and the answer starts with the word servitude.

Most of what people call mineral rights around the country traces back to common law fee ownership, where minerals get severed from the surface and owned outright, forever, the same as a piece of land. Louisiana runs on civil law instead, inherited from its French and Spanish legal history, and it doesn't recognize that kind of permanent, standalone mineral fee. What Louisiana landowners actually hold is a mineral servitude, a real right distinct from land ownership, and that difference shapes everything from how long you can hold minerals to how you sell them.

That single distinction is the starting point for understanding what an owner actually holds in Louisiana, and how it connects to the more specific interest types, servitude, royalty, and working interest, that show up in leases and deeds.

The Mineral Servitude, Not the Mineral Fee

Under the Louisiana Mineral Code, a mineral servitude is the right to explore for and produce minerals from a tract of land. It's created either by the landowner reserving it when selling the surface, or by granting it separately to someone else while keeping the surface. Critically, it's not ownership of the minerals in place the way Texas or Oklahoma law would describe it, it's a limited real right, and that right has to be exercised periodically or it extinguishes.

That limitation is the single biggest thing an out-of-state buyer or heir needs to understand about Louisiana minerals. A servitude that sits unused for ten consecutive years prescribes automatically, and the mineral rights revert to whoever owns the surface. There's no equivalent clock in most other oil and gas states.

The Landowner's Underlying Claim

Even when a servitude is outstanding, the surface owner retains an underlying interest in the minerals, sometimes described as the landowner's residual claim, which becomes a full ownership interest again the moment the servitude prescribes. This is different from the common law model, where a severed mineral estate can sit dormant forever without ever reverting to the surface.

It's why a Louisiana title check has to look at two things a Texas title check might not need to: who currently holds the servitude, and whether that servitude is still legally alive under the ten-year rule.

The Basic Real Rights the Mineral Code Recognizes

Beyond the servitude itself, Louisiana law recognizes a mineral royalty as its own basic real right, a share of production without the burden of exploration and development costs, and it can exist independently of a lease. The Mineral Code also recognizes the executive right, the authority to negotiate and grant mineral leases, which can be separated from the mineral servitude itself in some ownership structures. Working interests, by contrast, aren't a real right under Louisiana law at all, they're a contractual position created by a mineral lease.

Understanding which of these you actually hold, servitude, royalty, executive right, or a lessee's working interest, determines what decisions are yours to make and what a buyer is actually purchasing from you.

Why This Matters When You're Deciding to Sell

A buyer purchasing your Louisiana minerals is purchasing whichever real right you hold, subject to Louisiana's rules on prescription, and subject to whatever's recorded against it in the parish conveyance records, existing leases, prior partial sales, or unresolved succession issues. Getting the classification right up front, servitude versus royalty versus a fraction of either, avoids confusion later when it's time to draft a purchase agreement.

If you're not sure which type of interest you hold, the deed or the succession judgment that put the interest in your name is the place to look first, and the specific interest-type guides below go deeper into each one.
