Tex. Est. Code § 1160.251

If a guardian of an estate neglects to apply for authority to subject estate property to a lease for mineral development, pooling, or unitization, or authority to commit royalty or another interest in minerals to pooling or unitization, any person interested in the estate may, on written application filed with the county clerk, have the guardian cited to show cause why it is not in the best interests of the estate to make the lease or enter into an agreement.
