Express 1/128 “Product Fraction” and Explanatory Parenthetical Rebut Van Dyke’s Double-Fraction Presumption; Future-Lease Royalty Construed as Fixed When Measured from the Whole Tract

Introduction

This Supreme Court of Texas decision arises from a Reeves County oil-and-gas deed executed in May 1951. The deed—visibly altered from “Mineral Deed” to “Royalty Deed”—conveyed an interest described in multiple places as “one-one hundred and twenty-eighth (1/128)” and, in addressing future leases, used the phrasing “1/128 (1/16 of the usual 1/8 royalty).”

For roughly 70 years, the grantees and successors were paid a fixed 1/128 royalty without dispute. In 2020, respondent Scott W. Johnson (a successor to the 1951 grantees) sued petitioners (successors to the 1951 grantors) contending the deed instead conveyed a floating 1/16 nonparticipating royalty interest.

Two issues framed the appeal in the wake of Van Dyke v. Navigator Group, 668 S.W.3d 353 (Tex. 2023): (1) how to treat “double fractions” involving “1/8” in antiquated instruments, and (2) the role and elements of the presumed-grant doctrine. The court of appeals applied Van Dyke to award a floating 1/16 interest and refused to consider presumed-grant arguments as forfeited. The Supreme Court reversed.

Summary of the Opinion

The Court (Justice Young) held that although the deed’s use of “1/8” within a double fraction triggers Van Dyke’s starting presumption (that “1/8” may have been used as a term of art for the entire mineral estate), the deed’s plain language rebuts that presumption.

Key to rebuttal: the instrument repeatedly states the single fraction “1/128,” and the “double fraction” appears only as an explanatory parenthetical (“1/16 of the usual 1/8 royalty”) that “shows its work” to reach 1/128. Reading the deed as a whole, the Court concluded it unambiguously conveys a fixed 1/128 nonparticipating royalty interest, including under future leases. The Court reversed the court of appeals and reinstated the trial court’s summary judgment for the Cliftons and aligned successors.

Because the deed construction issue resolved the case, the Court did not decide whether the court of appeals erred in declining to remand for consideration of the presumed-grant doctrine, but it explained how that doctrine fits alongside double-fraction analysis and why it can sometimes obviate difficult construction disputes.

Analysis

Precedents Cited

  • Van Dyke v. Navigator Group, 668 S.W.3d 353 (Tex. 2023)
    Role in this case: Van Dyke supplies the “double-fraction presumption” for antiquated instruments using “1/8” in a double fraction: courts “begin” with a presumption that “1/8” was used as a term of art for the whole mineral estate, but the presumption is “readily and genuinely rebuttable.” The Court applied Van Dyke as the governing interpretive framework but held the court of appeals stopped too early—failing to credit strong textual indicators rebutting the presumption.
  • Hysaw v. Dawkins, 483 S.W.3d 1 (Tex. 2016)
    Role in this case: Cited for the principle that fraction-of-royalty instruments can contain apparently inconsistent terms that courts must harmonize by reading the document as a whole. It also provides background to the interpretive problem of double fractions (e.g., “1/3 of 1/8”).
  • French v. Chevron U.S.A. Inc., 896 S.W.2d 795 (Tex. 1995) (citing Altman v. Blake, 712 S.W.2d 117 (Tex. 1986))
    Role in this case: Supplies the canonical taxonomy of the “bundle of sticks” in the mineral estate (development, leasing, bonus, delay rentals, and royalty), supporting the Court’s explanation that conveyances may transfer some sticks while reserving others—particularly relevant to nonparticipating royalty arrangements.
  • Richardson v. Hart, 185 S.W.2d 563 (Tex. 1945)
    Role in this case: Cited as a contrast point for floating royalty characterization—illustrating that some “1/16 of 1/8” phrasings can describe a fraction “of the royalty” (floating) depending on the text. The Court distinguished the 1951 deed’s structure and its repeated expression of the single fraction 1/128.
  • Thomson v. Hoffman, 674 S.W.3d 927 (Tex. 2023)
    Role in this case: Supports the proposition that Van Dyke introduced a “new legal formulation” (even if consistent with prior precedents), which can matter procedurally when parties seek remand after an intervening doctrinal clarification.
  • Fair v. Arp Club Lake, Inc., 437 S.W.3d 619 (Tex. App.—Tyler 2014, no pet.)
    Role in this case: Quoted via Van Dyke to describe the presumed-grant doctrine as “title by circumstantial evidence” and akin to a common-law form of adverse possession.

The court of appeals also cited Tex. R. Civ. P. 94 to treat presumed-grant as forfeited for not being pleaded/raised earlier; the Supreme Court did not resolve that forfeiture ruling because deed construction was dispositive.

Legal Reasoning

1. Starting presumption, but the deed rebuts it

The Court followed Van Dyke’s instruction to “begin” with the presumption when “1/8” appears within a double fraction in an antiquated instrument. The purpose is historical: many parties once (mistakenly) treated “1/8” as the standard/maximum royalty and used expressions like “1/2 of 1/8” to mean “half of the entire interest,” not “1/16.”

But Van Dyke equally requires the next step: examine the full text for “express or structural” features showing the double fraction was “nothing more than a double fraction.” Here, the Court found abundant rebutting text:

  • The deed’s granting clause conveys “an undivided one-one hundred and twenty-eighth (1/128) interest.” That is a complete, single fraction—unattached to any “1/8” term-of-art phrasing.
  • The deed’s present-lease clause acknowledges a lease royalty of “1/8” and gives grantees “one-sixteenth (1/16) of the royalties provided for in said lease”—which, if treated arithmetically, yields 1/128 and matches the granting clause.
  • The future-lease clause grants “a 1/128 (1/16 of the usual 1/8 royalty)” share. The Court treated the parenthetical as an explanatory “show your work” statement demonstrating how the parties derived 1/128—rather than as a signal that “1/8” should be read as “the whole estate.”

In Van Dyke, the Court found “nothing in the text” to rebut the presumption; here, by contrast, the Court found “what is missing” is any plausible basis to read the instrument as not rebutting it. The repeated, consistent “1/128” formulation made the deed cohesive and unambiguous when read as a whole.

2. Fixed vs. floating: measured from the whole tract in the future-lease clause

The Court also held the future-lease royalty is fixed, not floating. The future-lease clause granted 1/128 of future royalties “given on said land or any part thereof,” i.e., it is measured from production on the entire described land, not a shifting “fraction of whatever royalty the lease later provides.” The Court treated this as an independent conveyance from the whole tract, reinforcing fixity at 1/128 of production.

3. Presumed-grant doctrine: doctrinal relevance, but not necessary to decide

The Court addressed the presumed-grant doctrine primarily to clarify its relationship to deed construction. It reiterated (via Van Dyke) that the doctrine asks a different question than text-meaning: it focuses on long-standing, real-world possession or claim consistent with ownership. The Court listed the three elements:

  1. a long-asserted and open claim, adverse to that of the apparent owner;
  2. nonclaim by the apparent owner; and
  3. acquiescence by the apparent owner in the adverse claim.

The Court emphasized that none of these elements turns on construing the deed and that the doctrine does not interpret instruments—it can instead resolve ownership despite what the text might suggest, much like adverse possession.

Importantly, the Court noted the parties’ decades-long shared understanding and payment history aligned with its textual reading (fixed 1/128), illustrating the ordinary and reassuring situation where the “paper title” and “practical title” point the same way. Because both pathways converged, the Court did not need to decide whether remand should have been granted to litigate presumed-grant.

Impact

  • Concrete rebuttal signal under Van Dyke: The decision clarifies that a deed can rebut the double-fraction presumption when it expressly states the multiplied product as a single fraction (here, “1/128”) and uses the double fraction in a parenthetical explanatory way. Drafters and litigants should treat “single-fraction consistency” across clauses as powerful evidence that the parties meant arithmetic rather than “1/8-as-estate” shorthand.
  • Parentheticals may be explanatory, not transformative: The Court’s method resists allowing an explanatory parenthetical to override the operative fraction repeated elsewhere in the deed. This promotes intra-instrument consistency and reduces the risk that “clarifying” language is later weaponized to create a different bargain.
  • Fixity analysis tied to the measurement base: By focusing on whether the future-lease clause is measured from “said land” (the whole tract) rather than from a changing lease royalty, the opinion provides a tract-based cue for fixed-vs-floating disputes, especially in nonparticipating royalty contexts.
  • Procedural aftershocks of Van Dyke remain: While not deciding the forfeiture/remand question, the Court’s discussion (and its citation to Thomson v. Hoffman) signals that litigants affected by Van Dyke’s clarified framework may press “interest of justice” remand arguments where presumed-grant or related doctrines were previously viewed as unavailable.

Complex Concepts Simplified

  • Double fraction: A fraction written as “A of B” (e.g., “1/16 of 1/8”). Read arithmetically, you multiply to get a single fraction (1/128). But in older oil-and-gas deeds, “1/8” was sometimes used loosely to mean “the whole mineral interest,” creating disputes about whether the math should be performed.
  • Van Dyke presumption: A starting assumption for antiquated instruments: when “1/8” appears in a double fraction, presume the parties used “1/8” as a term of art for the whole mineral estate—unless the text shows otherwise. This case is a rebuttal example.
  • Fixed vs. floating royalty: A fixed royalty is a constant share of production (e.g., always 1/128 of production), regardless of the lease royalty negotiated later. A floating royalty is a fraction of whatever royalty the lease provides (e.g., always 1/16 of the lease royalty).
  • Nonparticipating royalty interest (NPRI): A royalty interest that generally does not include the right to lease or to receive lease bonuses or delay rentals, but entitles the owner to a share of production/free-of-cost royalty.
  • Presumed-grant doctrine: A title doctrine akin to adverse possession that can recognize ownership based on long, open, adverse claim plus the other side’s long nonclaim and acquiescence—sometimes making fine-grained deed interpretation unnecessary when decades of conduct settle “who owns what.”

Conclusion

The Supreme Court of Texas held that the 1951 “Royalty Deed” conveyed a fixed 1/128 royalty interest, reversing the court of appeals and reinstating the trial court’s summary judgment. The opinion’s central contribution is practical and text-driven: even when “1/8” appears in a double fraction and triggers Van Dyke’s presumption, that presumption is overcome where the instrument repeatedly states the arithmetic product as a single fraction and uses the double fraction parenthetically to explain that product. The decision strengthens deed-wide consistency as the touchstone for rebuttal and underscores that long-settled payment practice and title doctrines like presumed-grant exist to keep oil-and-gas ownership aligned with both text and reality.
