Louisiana is a civil-law jurisdiction. Estates do not "probate" in the common-law sense; they go through a "succession," governed by Title XII of Book III of the Louisiana Civil Code and the procedural rules at La. C.C.P. arts. 2811 et seq. Successions are filed in the district court of the parish of the decedent’s domicile.
Two principal tracks are in routine use:
1. Succession with administration (La. C.C.P. arts. 3091 et seq.) — used when creditor exposure exists, when heirs do not unanimously consent to non-administered handling, or when the estate is otherwise contested. The court appoints an administrator or executor and supervises the administration.
2. Succession without administration / "judgment of possession" (La. C.C.P. arts. 3001–3008) — used when all heirs are competent adults, accept the succession unconditionally, and there are no creditor concerns. The court enters a judgment of possession placing the heirs in title without administration. This is the most common track for clean inherited mineral estates.
For mineral interests of meaningful value, a judgment of possession that specifically describes each mineral interest by parish, section, township, and range — followed by recording of the judgment in every situs parish — is the standard workflow. The judgment of possession (with descriptive schedule attached) is the document mineral lessees and parish recorders rely on to update title.
Three production groupings drive the bulk of contemporary Louisiana mineral-succession volume:
1. Haynesville Shale (northwestern Louisiana) — De Soto, Caddo, Bossier, Red River, Sabine, and Bienville parishes. Modern horizontal Haynesville development is the dominant ongoing activity; the play has been continuously active since 2008 with renewed intensity tied to LNG-export demand. Major operators include Aethon, Comstock, Indigo, Rockcliff, and BPX. Document packages typically process in 30–60 days for complete submissions.
2. Tuscaloosa Marine Shale and central Louisiana legacy — East and West Feliciana, Avoyelles, Pointe Coupee, and Catahoula parishes. Smaller-scale activity with mixed legacy and modern interests.
3. Gulf Coast and southeastern Louisiana — Terrebonne, Lafourche, Plaquemines, St. Mary, and Iberia parishes. Long-history conventional and offshore-adjacent production with many multi-generational interests.
A Louisiana-specific consideration: the parish of De Soto has been one of the most active mineral-recording parishes in the United States since the modern Haynesville era began. De Soto title work moves through the parish clerk’s office at high volume, and curative for missing successions on inherited interests is a routine workload there.
The Louisiana Mineral Code (La. R.S. 31:1–215) governs the substantive nature of mineral rights in Louisiana and differs structurally from the common-law mineral-estate doctrine used in every other producing state.
Key distinctions for estate practice:
— A "mineral servitude" (La. R.S. 31:21 et seq.) is the closest Louisiana analog to a severed mineral estate. It is a real right but not a fee estate; it gives the holder the right to explore for and reduce minerals to possession.
— A "mineral royalty" (La. R.S. 31:80 et seq.) is a cost-free share of production, similar to a common-law nonparticipating royalty interest, but classified as a real right under the Civil Code.
— A "mineral lease" (La. R.S. 31:114 et seq.) creates a real right in the lessee analogous to a common-law oil-and-gas lease.
— The Mineral Code’s prescription regime (La. R.S. 31:27–62, 85–91) imposes a 10-year prescription of nonuse on mineral servitudes and mineral royalties. If no qualifying use occurs for 10 consecutive years, the servitude or royalty extinguishes and the underlying mineral right reverts to the landowner.
This 10-year prescription is the most consequential Louisiana-specific feature for inherited interests. A mineral servitude held by a decedent that has been entirely passive for 10 years — no production, no reworking, no recorded interruption — may have already extinguished by operation of law before the succession is opened. At intake on a Louisiana mineral-asset succession, confirm whether each servitude has been used within the prior 10 years; if not, the interest may no longer exist regardless of how it appears on the historical chain.
Louisiana does not currently impose a state inheritance tax. The Louisiana inheritance tax was effectively phased out for deaths after July 1, 2004, and Louisiana does not have a state estate tax.
For mineral-asset successions, the consequences:
— Federal estate tax applies if the gross estate exceeds the federal exclusion ($13.99M per decedent for 2025; the indexed amount — confirm the current-year figure on the IRS Rev. Proc. release).
— No Louisiana estate-tax filing is required at any value.
— The mineral appraisal supporting the federal Form 706 is the only valuation document required for tax purposes.
For non-Louisiana-domiciled decedents who owned Louisiana mineral interests, no Louisiana inheritance-tax filing is required, but ancillary succession proceedings in the situs parish are required for title purposes — the home-state letters do not bind Louisiana real property.
Note on ongoing tax: Louisiana levies a severance tax on oil and gas (gas at a fluctuating rate tied to a statutory formula; oil generally at 12.5%) and parishes levy ad valorem tax on producing minerals. These appear on the royalty owner’s pay stub or are netted in operator accounting. They are operational severance items — not estate-tax items — but practitioners reconstructing pre-DoD royalty income for the federal Form 706 valuation should expect to see them.
Ancillary Louisiana succession for a non-domiciliary decedent uses the same Code of Civil Procedure machinery as a domiciliary succession. The personal representative or heirs file a petition for ancillary probate of the will (if any) and for ancillary appointment in the situs parish district court.
A few practical notes:
— For an unconditional acceptance by all heirs with no creditor concerns, an ancillary judgment of possession can be obtained without formal administration — mirroring the domestic non-administered track.
— The judgment of possession must specifically identify each mineral interest. A general residuary clause is insufficient for parish-clerk recording purposes; the schedule must list interest by parish, section, township, range, and conveyance reference.
— The judgment must be recorded in every Louisiana situs parish; minerals in three parishes = three recordings.
— Lessees in the major Haynesville parishes have well-established protocols for processing recorded judgments of possession.
Common curative tasks alongside succession:
— Recording of the judgment of possession in every situs parish.
— Confirmation that no servitude or royalty has prescribed under the 10-year nonuse rule.
— Affidavits of identity to clear name discrepancies in the chain.
— Coordination with operators for release of suspense royalty post-recording.
— Late-royalty interest accrual under La. R.S. 31:138.1 can also become a succession asset where the decedent had pending claims.
Five issues recur on Louisiana mineral-succession work:
1. Missing prescription of nonuse. A mineral servitude or royalty that has not been used in 10+ years may have extinguished by operation of law before the succession is opened. The interest may not exist regardless of how it appears on the historical chain. Confirm use within 10 years at intake.
2. Insufficient property description in the judgment of possession. A general residuary clause is insufficient for parish-clerk recording. Each interest must be specifically described by parish, section, township, range, and conveyance reference.
3. Failing to record the judgment of possession in every situs parish. Louisiana recording is per-parish; a Haynesville estate with interests in De Soto, Bossier, and Caddo parishes requires three recordings.
4. Treating Louisiana mineral interests as common-law mineral fees. Louisiana mineral servitudes and royalties are real rights under the Civil Code, not fee estates. Drafting estate documents using common-law mineral-fee language can create ambiguity and curative cost.
5. Underestimating Haynesville production volatility for federal Form 706 valuation. Haynesville wells exhibit steep early decline curves; a single year of pre-DoD royalty data may overstate or understate sustained income. Provide the appraiser with three to five years of stub data when available, plus operator decline-curve context.
Under the Louisiana Mineral Code (La. R.S. 31:27–62 for servitudes and 31:85–91 for royalties), a mineral servitude or mineral royalty extinguishes by operation of law if no qualifying use occurs for 10 consecutive years. Qualifying uses include production, drilling, reworking, and certain recorded acts of interruption. For a decedent’s mineral interest that has been entirely passive for 10+ years, the interest may have already prescribed before the succession is opened — meaning it no longer exists regardless of how the historical chain appears. At intake, confirm whether each servitude or royalty has been used within the prior 10 years.
No. Louisiana phased out its inheritance tax for deaths after July 1, 2004 and does not impose a state estate tax. Federal estate tax applies if the gross estate exceeds the federal exclusion; no separate Louisiana filing is required at any value.
Yes for title purposes. The Texas letters do not bind Louisiana real property; ancillary succession proceedings must be opened in the De Soto Parish district court. For an unconditional acceptance by all heirs with no creditor concerns, an ancillary judgment of possession can be obtained without formal administration. The judgment must specifically describe each mineral interest by parish, section, township, range, and conveyance reference, then be recorded in De Soto Parish.
A Louisiana mineral servitude (La. R.S. 31:21 et seq.) is a real right giving the holder the right to explore for and reduce minerals to possession, but it is not a fee estate in the minerals themselves. By contrast, a common-law severed mineral estate is itself a fee. The most consequential practical difference is the 10-year prescription of nonuse: a Louisiana servitude that goes 10 years without qualifying use extinguishes by operation of law, with the right reverting to the landowner. Common-law mineral fees do not have an analogous self-executing reversion mechanic in most states.
Each mineral interest must be specifically identified by parish, section, township, range, and conveyance reference in the schedule attached to the judgment. A general residuary clause covering "all mineral interests of the decedent" is insufficient for parish-clerk recording purposes and will create curative work for any subsequent lease or transfer. Build the schedule from a complete inventory of the decedent’s mineral interests before the judgment is rendered.

Ohio is one of the few producing states where inherited mineral rights can genuinely be lost to the surface owner through inaction. The Dormant Mineral Act sets out exactly how that happens — and exactly how heirs can stop it. If your family once owned minerals in eastern Ohio, the time to check is before a notice arrives, not after.
Mississippi mineral interests — Tuscaloosa Marine Shale royalties along the southwestern fairway, legacy Mississippi Salt Basin oil and gas across the south, and shallow conventional production scattered statewide — pass through estate proceedings under the Mississippi Code (Title 91) in the chancery courts. The defining institutional feature of Mississippi mineral practice is the chancery-court system itself: equity-rooted, county-based, and procedurally distinct from the common-law probate courts found in most other states.
Arkansas mineral interests — dormant Fayetteville Shale royalties across the Arkoma fairway, legacy Smackover oil and brine in the south, and the contemporary lithium-extraction pivot in the Smackover — pass through probate under Title 28 of the Arkansas Code Annotated. The defining feature of Arkansas mineral practice is the gap between the play’s 2008–2016 Fayetteville heyday and its current low-activity baseline, which routinely surfaces unaddressed succession gaps in inherited interests.
West Virginia mineral interests — dominantly Marcellus and Utica royalties in the northern panhandle and north-central counties — pass through estate proceedings under Chapters 41 (wills) and 44 (decedents’ estates) of the West Virginia Code. The defining feature of WV mineral practice is the layered nineteenth-century severance history: an estimated 1.3 million distinct mineral interests, many traceable to severances recorded in the 1880s–1910s, generate disproportionate curative volume per estate.
