Dormant Mineral Act

Severed mineral ownership creates a records problem. Minerals conveyed in 1918 pass by inheritance through four generations, the descendants scatter, nobody records anything, and a surface owner in the present day cannot find or contact the people who own what is beneath their land. Dormant mineral statutes are the legislative response: after a long enough period of inaction, the minerals go back to the surface.

Not every state has one, and the states that do differ on almost every operative detail. Treat the specific statute as controlling.

What typically counts as “use”

Statutes generally list saving events that reset the clock. Common ones:

• Actual production of oil, gas, or other minerals from the tract.
• A recorded lease, or a lease still in effect.
• A recorded conveyance, mortgage, or transfer of the mineral interest.
• Payment of taxes separately assessed on the mineral interest, where the state separately assesses minerals.
• A recorded statement or affidavit of claim, filed for the express purpose of preserving the interest.
• A court judgment or a probate proceeding that shows the interest in the record.

Receiving a royalty check does not always qualify by itself, and neither does knowing you own something. What generally matters is whether the public record shows activity.

The notice question

Some statutes require the surface owner to give notice — by mail if the mineral owner can be found, by publication if not — and give the mineral owner a window to file a claim. Others operate automatically, with lapse occurring by force of statute and no letter ever sent.

That distinction decides whether a family gets a chance to react. Indiana’s lapse act and Michigan’s statute have both produced the harsher pattern, and Kansas’s notice-by-publication procedure means the only warning may have appeared in a small-town newspaper. Ohio’s Dormant Mineral Act has generated extensive litigation over exactly which version of the statute applies and what notice was required. Our journal covers each: Ohio, Michigan, Indiana, and Kansas.

Louisiana is a different system

Louisiana does not use a dormant mineral act. Under its civil-law framework a severance creates a mineral servitude that prescribes for nonuse after ten years — a shorter clock, with its own rules on interruption. Do not reason from a common-law dormancy statute to a Louisiana interest.

Practical steps if you may hold dormant minerals

1. Identify the state and county and read that state’s statute, or have counsel read it. The period, the saving events, and the notice rules are all state-specific.
2. Pull the record in that county for the mineral interest: any lease, conveyance, affidavit, or probate filing in the relevant window.
3. Record something if the interest is still alive. Where the statute allows a claim or affidavit, filing one is inexpensive relative to what it protects.
4. Bring title current. An unprobated death in the chain is both a suspense problem and a dormancy exposure — the record does not show who owns the interest.
5. Move promptly if a notice arrived. These windows are short and, once closed, generally not reopened.

Why this shows up in valuations

Any careful buyer checks dormancy exposure in states that have these statutes, because it goes to whether the interest exists at all. An interest with a long quiet stretch in the record is not necessarily lost, but it does carry a question that has to be resolved.

If you think a family interest may have gone quiet — especially in Ohio, Michigan, Indiana, or Kansas — the useful first move is to find out what the county record actually shows. We do that research at no charge, and we will tell you plainly if the news is bad.
