“All Right, Title, and Interest” Means All—Unless the Instrument Expressly Reserves It; Limited Exhibit Descriptions Require Lease-Specific Scope Analysis

Introduction

In Mcardle Family Partnership v. Antero Resources Corporation (4th Cir. Apr. 20, 2026) (unpublished), the McArdle Family Partnership (MFP) alleged that it owned certain oil-and-gas royalty-related interests in West Virginia leasehold estates and that Antero Resources Corporation, Key Oil Company, and Franklin L. Butler breached contract by failing to pay royalties. The dispute turned largely on title: whether a 1996 assignment from James Drilling Corporation and the Shearers to Key Oil had already conveyed the relevant interests, leaving nothing for James Drilling to assign to MFP in 2008.

The key issues were (1) how broadly to read a conveyance of “all right, title and interest” where the instrument contains no explicit reservations, and (2) how to treat leases (the Hudson leases) where the assignment’s Exhibit A described only specific portions of the leasehold acreage rather than the leases in full.

Because the Fourth Circuit designated the opinion “UNPUBLISHED,” it is “not binding precedent in this circuit,” but it is instructive on conveyancing interpretation, especially in royalty-interest disputes.

Summary of the Opinion

The Fourth Circuit affirmed summary judgment for Defendants as to the Towner and Stone leases, holding the 1996 assignment unambiguously conveyed “all” of the assignors’ interests in those leases to Key Oil, with no reservations. Thus James Drilling had no overriding royalty interests left to convey to MFP in 2008.

But the court vacated and remanded as to MFP’s alleged 1/64 net profits interest in the Hudson leases. Unlike the Towner and Stone leases, Exhibit A did not assign the Hudson leases wholesale; it identified “specific parts” of the Hudson leasehold estates. Because MFP claimed an interest across the entire Hudson acreage, the district court erred by treating the limited 1996 Hudson description as necessarily extinguishing any net profits interest for all Hudson acreage.

The court also noted it relied on contract interpretation principles and, “Unlike the district court,” based no part of its decision on “the doctrine of extinguishment by merger.”

Analysis

Precedents Cited

• Young v. Equinor USA Onshore Props., Inc., 982 F.3d 201 (4th Cir. 2020): The court cited Young for de novo review of cross-motions for summary judgment and for de novo review of contract interpretation underlying summary judgment. This citation framed the appellate posture: the Fourth Circuit owed no deference to the district court’s interpretation of the assignment.
• Francis v. Allstate Ins. Co., 709 F.3d 362 (4th Cir. 2013): Cited for the Erie principle in diversity cases—federal courts apply the forum state’s substantive law, including its choice-of-law rules. Here, that meant West Virginia law governed interpretation of the assignment.
• Faith United Methodist Church & Cemetery of Terra Alta v. Morgan, 745 S.E.2d 461 (W. Va. 2013): Quoted for the proposition that deeds are construed using general contract interpretation principles. The Fourth Circuit treated the 1996 assignment as a contract-like instrument whose text controls.
• Meadows v. Belknap, 483 S.E.2d 826 (W. Va. 1997): The court relied on syllabus point language: where a conveyance includes “no words of limitation,” it passes “the fee simple or the whole estate or interest” unless the instrument shows a contrary intent. This was central to the “all right, title and interest” analysis.
• DWG Oil & Gas Acquisitions, LLC v. S. Country Farms, Inc., 796 S.E.2d 201 (W. Va. 2017), quoting Hall v. Hartley, 119 S.E.2d 759 (W. Va. 1961): The Fourth Circuit invoked the West Virginia rule that an exception or reservation reducing a clear grant must be expressed in “certain and definite language.” This directly undercut MFP’s attempt to find an implied reservation of overriding royalty/net profits interests.
• McArdle Fam. P'ship v. Antero Res. Corp., No. 24-1347, 2025 WL 1167651 (4th Cir. Jan. 31, 2025): Mentioned as the prior appeal dismissed for lack of jurisdiction, explaining why a Rule 54(b) final judgment was later entered to permit appellate review.
• Dictionary Authorities (Black’s Law Dictionary, 12th ed. 2024): The opinion quoted definitions of “overriding royalty interest” and “net profits interest” to clarify the nature of the claimed interests, reinforcing why precise drafting and clear reservation language matter.

Legal Reasoning

1) Towner and Stone: “All” meant all, and no implied reservation survived

The 1996 assignment’s granting clause conveyed to Key Oil “all of [the assignors’] right, title and interest” in the leases and leasehold estates described in Exhibit A, followed by the phrase “except as hereinafter provided.” But the instrument included no subsequent exceptions. Applying Meadows v. Belknap and DWG Oil & Gas Acquisitions, LLC v. S. Country Farms, Inc. (quoting Hall v. Hartley), the court treated the grant as unqualified and rejected the notion that a duty to “comply with the terms and conditions” of the leases could implicitly reserve overriding royalty interests or net profits interests to the assignors.

Because Exhibit A specifically included the Towner and Stone leases (with identifying details such as acreage, dates, location, recording references, and well numbers), the consequence was straightforward: whatever interests James Drilling and the Shearers had in those leases in 1996 were conveyed to Key Oil then. Therefore James Drilling could not convey overriding royalty interests in those leases to MFP in 2008.

Notably, the Fourth Circuit affirmed without adopting the district court’s alternative “merger” rationale, emphasizing that the result followed from plain-language conveyancing rules.

2) Hudson: a limited Exhibit A description prevented a global “nothing left to convey” conclusion

The Hudson leases differed because Exhibit A did not assign “the entirety” of the Hudson leasehold estates. Instead, it identified “specific parts” (five 40-acre portions plus areas within 1,000 feet of existing wells). MFP, however, alleged a 1/64 net profits interest in production from the entire Hudson acreage and traced that claim to a 1961 conveyance referring broadly to “any and all of the income” derived from oil and/or gas produced and sold from the two Hudson leases.

The district court reasoned from the 1996 assignment to a categorical conclusion: James Drilling had no corporate net profits interest in the Hudson leases that could have been conveyed in 2008. The Fourth Circuit found that step insufficiently analyzed because the premises were narrower than the conclusion: a partial assignment of “specific parts” does not automatically prove that no net profits interest existed (or survived) with respect to unassigned portions, or that the net profits interest—if defined across the full leases—was entirely transferred by an assignment describing less than the whole.

Accordingly, the panel vacated summary judgment on the Hudson net-profits claim and remanded for the district court to address the relationship between (a) the scope of the claimed net profits interest and (b) the scope of what the 1996 assignment actually conveyed as to Hudson.

Impact

• Drafting and title litigation: The opinion reinforces a strict, text-centered approach: broad “all right, title and interest” language will be treated as comprehensive unless the instrument uses “certain and definite” reservation language. Parties seeking to retain ORRIs or NPIs should not rely on contextual clauses (e.g., compliance-with-lease terms) as substitutes for explicit carve-outs.
• Exhibits can control scope: Where an assignment incorporates an exhibit that narrows the described subject matter (as with “specific parts” of a leasehold), courts may require a granular, acreage- and interest-specific analysis rather than assume the assignment resolved all interests across the entire underlying lease.
• Procedural lesson in complex, multi-count oil-and-gas cases: The litigation posture (including the earlier jurisdictional dismissal and later Rule 54(b) judgment) underscores the importance of finality and careful claim segmentation for appellate review in multi-claim royalty disputes.
• Persuasive—not binding—authority: Though unpublished, the decision may be cited for its reasoning in similar disputes, especially in federal courts applying West Virginia conveyancing law.

Complex Concepts Simplified

• Overriding royalty interest (ORRI): A share of production or revenue carved out of the lessee’s interest, typically free of production costs. It is a burden on the working interest and usually continues as long as the underlying lease continues.
• Net profits interest (NPI): A right to a portion of profits—payable only if profits exist—so its value depends on how “profits” and allowable costs are defined.
• Exception vs. reservation: Both reduce what the grantee receives compared to the broad grant; West Virginia requires that such reductions be stated in clear, definite terms when the granting clause is clear.
• “All right, title and interest”: Conveyancing shorthand for a complete transfer of whatever the grantor owns in the described property. Without an express carve-out, courts generally will not infer one.
• Rule 54(b) judgment: A mechanism allowing entry of final judgment on fewer than all claims in a case, enabling an immediate appeal despite other claims remaining.

Conclusion

The Fourth Circuit’s decision delivers two complementary lessons under West Virginia conveyancing principles: (1) a clear assignment of “all right, title and interest,” with no stated exceptions, will be enforced as a complete transfer—foreclosing implied reservations of royalty-related interests; but (2) where the assignment’s exhibit limits what is conveyed (as with “specific parts” of a leasehold), courts must analyze whether and how that limitation affects claims to interests alleged across the entire lease acreage. The result—affirmance as to Towner and Stone, vacatur and remand as to Hudson—turns on the text and scope of the 1996 assignment itself.
