The Texas Supreme Court held that the owner of a right of first refusal was not too late in asserting it because the statute of limitations did not start running until the owner knew or reasonably could have known that the right had been triggered. Carl M. Archer Trust No. Three v. Tregallas,566 S.W.3d 281 (Tex. 2018). The sellers of a surface estate granted the buyer a right of first refusal to purchase the mineral estate within 60 days after being given notice of an intent to sell those rights. The right of first refusal was recorded. Without giving such notice, the owner of the mineral estate sold that estate to a third party in 2007. Four years later (and outside the statute of limitations), the owner of the right of first refusal found out about the conveyance of the mineral estate and immediately sued to nullify it. The statute of limitations was tolled because the injury was "inherently undiscoverable" even with due diligence.
