Mattie Garrett v. Dils Company

Summary

The Texas Supreme Court affirmed the Court of Civil Appeals, holding that the deed conveyed to the respondent an undivided one‑eighth interest in the minerals (i.e., a one‑eighth royalty) under both the lease existing at the time of the deed and any subsequent leases. The decision rests on a construction of the deed that gives effect to the parties' intent, applying the rule that doubt is resolved against the grantors.
