Essential judicial standards governing mineral reservations, deed warranties, and overconveyances explained in plain English.
When a seller sells land with a general warranty deed while attempting to reserve half the mineral rights, but previous owners already own half the minerals, the seller loses their reservation. The deed warranty guarantees the buyer gets what was promised first.
Mineral ownership contains five separate rights: (1) drilling rights, (2) leasing executive rights, (3) bonus rights, (4) delay rental rights, and (5) royalty rights. If an owner conveys royalty rights only, the recipient receives a Non-Participating Royalty Interest (NPRI) with no vote in leasing.
Standard deed "cover-all" clauses are legally intended only to prevent accidental tiny survey strips or gores from clouding title along fences or roads. An operator cannot use a cover-all clause to grab a separate, substantial 40-acre tract not specifically described.
The person holding executive leasing rights owes a fiduciary duty to non-executive royalty owners. The executive holder cannot take a giant cash bonus or an overriding royalty under the table while signing a low royalty rate that shortchanges the royalty owner.

Under Texas Property Code § 5.028, a nonmaterial correction (such as an obvious misspelling of a name, minor clerical number typo, or recorded volume/page citation error) can be made by an affidavit from a landman with knowledge. However, under § 5.029, any material change—such as changing mineral percentages, adding an omitted person, or moving boundary lines—requires a formal Correction Deed signed by all original parties or their legal heirs.
Under Texas Civil Practice & Remedies Code § 16.035, a mortgage lien expires by statute of limitations four years after the scheduled loan payoff date (or four years after recording if no payoff date is listed). Landmen frequently cure this with an Affidavit of Statute of Limitations certifying that no foreclosure occurred and that the lender has asserted no claim.
Under Louisiana Mineral Code Article 29, good faith drilling operations conducted to a depth with a reasonable prospect of finding commercial minerals interrupts prescription. Even if the well ends up a dry hole, the 10-year clock resets, as long as the operations were genuine and conducted in good faith.
A "fixed" Non-Participating Royalty is a set share of all production (e.g. "an undivided 1/16th of all production"), regardless of what royalty rate is leased in the future. A "floating" royalty is tied directly to future leases (e.g. "one-half of all royalty negotiated in any future lease"). The exact wording of the deed reservation determines which one applies.
