In Moczygemba v. Moczygemba, a mother sold a ranch to two sons and later sued them for breach of fiduciary duty for not disclosing to her that the deeds also transferred mineral interests. No. 04-14-001100-CV, 2015 Tex. App. LEXIS 1536 (Tex. App.—San Antonio February 18, 2015, no pet. hist.). The trial court granted summary judgment for the defendants due to the statute of limitations. The court of appeals affirmed, holding that the discovery rule did not apply. The discovery rule applies where injury is inherently undiscoverable and is objectively verifiable. There was a good argument that injury was discoverable because the deeds expressly conveyed the minerals. But the court of appeals held that the injury was not objectively verifiable. The court held that the deposition testimony of the plaintiff was not objectively verifiable evidence, and deeds did not prove that mineral interests were wrongfully transferred, just that they were transferred.
