Background
A 1944 deed conveyed 640 acres in Borden County while reserving to the grantors “an undivided one-half of the usual and customary one-eighth (1/8) royalty.” A later clause gave the grantee the exclusive right to lease the property and receive bonuses and rentals, while describing the grantors’ “sole and only right” as receiving one-sixteenth of production as a royalty. The Coffields, successors to the grantors, contended that the deed reserved one-half of whatever royalty a future lease provided; the Wolfs, successors to the grantee, argued that it reserved a fixed one-sixteenth royalty.
The parties filed competing summary-judgment motions. The trial court granted the Coffields’ motion and declared that the deed reserved a floating royalty equal to one-half of the royalty payable under any lease. It also overruled the Wolfs’ objections to a stipulation concerning the deed and a landman’s declaration regarding ownership. The Wolfs appealed both the deed construction and the evidentiary rulings.
The Court’s Holding
The Eleventh Court of Appeals affirmed. Applying the Texas Supreme Court’s double-fraction framework, the court began with the presumption that “one-half of the usual and customary one-eighth royalty” used one-eighth as a term of art representing the standard landowner’s royalty. The primary reservation clause therefore reserved a floating one-half royalty interest, not a fixed one-sixteenth interest.
The later reference to one-sixteenth did not rebut that presumption. Because the double fraction appeared in the primary reservation clause and the single-fraction product appeared only later in the future-lease clause, the court treated the latter as explanatory rather than as modifying the reservation. The court also held that any error in admitting the challenged stipulation or landman’s declaration was harmless because its decision rested on the unambiguous deed language, reviewed de novo. Although the opinion discussed the presumed-grant doctrine, the court did not decide its application because it was not properly presented on appeal; it additionally noted that the Wolfs’ failure to challenge the trial court’s implicit rejection of their presumed-grant defense supported affirmance.
Key Takeaways
- A deed reserving “one-half of the usual and customary one-eighth royalty” presumptively creates a floating interest equal to one-half of the royalty payable under a lease.
- A later reference to the mathematical product of a double fraction does not necessarily create a fixed royalty, particularly when the double fraction appears in the primary reservation clause and the product appears only in a future-lease clause.
- Admission of extrinsic summary-judgment evidence is harmless when the appellate court’s de novo decision rests solely on an unambiguous deed.
- The presumed-grant doctrine must be properly raised and briefed for appellate consideration.
Why It Matters
The decision applies Texas’s modern double-fraction cases to a deed that paired a floating-interest formulation with a later reference to one-sixteenth. It emphasizes that courts must examine the placement and function of each clause rather than treating the stated mathematical product as automatically controlling.
For mineral-title disputes, the ruling reinforces that “usual one-eighth” language generally operates as a placeholder for the full lease royalty unless the instrument’s text or structure provides a demonstrable basis for treating it as a literal fraction.
