In much of north Texas, it’s common for the owners of the surface rights to own little—or sometimes none—of the mineral rights beneath their land. This separation didn’t happen by accident. Historically, Texans believed that the minerals under the soil—especially oil and gas—might one day bring significant financial value. So, when land was sold, owners often kept the mineral rights for themselves.

Over time, those mineral rights were passed down through families. Each generation might divide their interest among several heirs, and those heirs might divide it again. After decades of inheritances, sales, and subdivisions, a single property could end up with a long list of mineral owners, each holding only a fractional share.

How did we get here?

That’s a question that could fill an entire Texas history book, but here’s the short version.

In the early to mid‑1800s, not long after Texas joined the Union, people from Mexico were crossing into Texas to collect salt—yes, plain old salt, which legally counts as a mineral. Landowners weren’t thrilled about strangers taking resources from their property. Over the next 80 or so years, a series of laws, court decisions, and eventually a ruling from the Texas Supreme Court established a key principle:

The owner of the surface estate also owns the mineral estate beneath it—unless those rights are legally separated.

This legal framework created two distinct “estates”:

• Surface estate – the land itself

• Mineral estate – the resources below it

And importantly, the mineral estate was deemed dominant over the surface estate. That means mineral owners have the legal right to use the surface as reasonably necessary to access and produce their minerals.

So yes—Texas’ entire system of split estates, fractional mineral ownership, and mineral dominance can be traced back, in part, to people crossing the border to gather salt.

That’s a good place to pause. If you’re curious to dig deeper, searching for “Texas mineral rights history” will open up a fascinating rabbit hole.
