Recently Discovered Mineral Rights in Montana or North Dakota? Here's What You Need to Know

September 30, 2026

If someone from an oil or gas company just called you or sent you a letter about mineral rights that belonged to your parent, grandparent, or another family member who passed away, you might have just learned about property your family owns that you didn't even know existed. This happens a lot in eastern Montana and western North Dakota. Families in these areas often kept their rights to oil, gas, and minerals even after they sold the land above ground.


Good News and a Challenge


The good news: if a company is contacting you about these mineral rights, they may be worth real money.


The challenge: before you can lease them, sell them, or get paid from them, you usually need to legally transfer ownership from the person who died to the rightful heirs. That's where our law firm can help. Our lawyers are licensed in both Montana and North Dakota, and we regularly help families complete the legal work needed to prove ownership and transfer inherited mineral rights.


Why Is an Oil Company Calling Me About a Relative Who Died?


Oil and gas companies do research on who owns mineral rights before they drill wells or buy leases. Sometimes they find out that the person listed as the owner died years ago—maybe even decades ago—and the mineral rights were never officially passed down to the next generation. The company or their representative will then try to find that person's descendants.


For you, the call might be a surprise: "Your grandmother owned mineral rights here, and we think you may have inherited part of them." The company might want to lease the minerals, buy them, or figure out who should get royalty payments. But just because they found you doesn't mean the legal paperwork is done. That's where a lawyer who knows probate, real estate, and mineral law comes in.


Your Family Can Still Own Minerals Even After Selling the Land


Mineral rights can be separated from the land on the surface. Here's an example: imagine your family owned a ranch in Richland County, Montana, back in the 1950s. When they sold the ranch, the deed might have said they were keeping some or all of the oil, gas, and mineral rights called “reserving.” Years later, your family might not own any land in that county anymore, but they could still own valuable mineral rights under property that someone else now owns.


Those rights can pass down through your family. The problem happens when the paperwork doesn't get updated along with the family tree. A mineral interest might still be listed under your great-grandparent's name, even though they died 40 years ago. Multiple generations may have passed away since then, which means you might need to rebuild the ownership chain before today's heirs can prove clear ownership.


"They Found Me" Doesn't Mean the Title Is Clear


If an oil company or landman already tracked you down as a possible heir, they've done some detective work—but there's often still legal work to finish. Depending on your situation, figuring out who owns what can involve looking at:


  • The deed or other document that created or kept the mineral rights
  • Old mineral deeds and transfers
  • Probate records for the person who died
  • Wills and trusts
  • Death certificates
  • Family relationships and who the heirs are
  • Whether probate happened in a different state
  • Whether multiple generations of owners have died
  • Whether the mineral rights were mentioned in an earlier estate
  • What fraction each heir or beneficiary owns
  • The right legal process to put the mineral rights in the current owners' names


Every case is different. A simple one might have one person who died and a few easy-to-identify heirs. A complicated case might involve several generations, many descendants, or probate in multiple states.


You Might Need an Extra Probate or Estate Proceeding


One common situation: a person who lived and died outside Montana or North Dakota but owned mineral rights in one of those states. For example, say your grandfather lived in Minnesota when he died, but he kept mineral rights in eastern Montana. His Minnesota estate might have been fully handled years ago, but the Montana mineral rights might never have been addressed. You might need additional legal proceedings in Montana to officially pass down that Montana property. The same thing can happen with North Dakota mineral rights.


What you need to do depends on the facts—where the person lived, whether they had a will, whether an estate was opened before, how long ago they died, and what the mineral records show. Our lawyers can review your situation and figure out what legal process will work.

 

What If the Mineral Owner Died a Long Time Ago?


Inherited mineral-rights cases often involve people who died decades ago. The first step is usually figuring out exactly what the person owned and what happened to it after they died. Sometimes the chain is straightforward. Other times, you have to trace ownership through multiple generations.


For example:


Original Owner → Child → Grandchild → Current Heirs


If each person in that chain has died, you may need to look at the legal effect of each death to figure out who owns the mineral rights today and what percentage each person owns.
