Tex. R. Civ. P. 649
Personal property levied on under execution shall be offered for sale on the premises where it is taken in execution, or at the courthouse door of the county, or at some other place if, owing to the nature of the property, it is more convenient to exhibit it to purchasers at such place. Personal property susceptible of being exhibited shall not be sold unless the same be present and subject to the view of those attending the sale, except shares of stock in joint stock or incorporated companies, and in cases where the defendant in execution has merely an interest without right to the exclusive possession in which case the interest of defendant may be sold and conveyed without the presence or delivery of the property. When a levy is made upon livestock running at large on the range, it is not necessary that such stock, or any part thereof, be present at the place of sale, and the purchaser at such sale is authorized to gather and pen such stock and select therefrom the number purchased by him.
