Texas Local Government Code - LOC GOV'T § 42.901. Apportionment of Extraterritorial Jurisdictions That Overlapped on August 23, 1963

(a) If, on August 23, 1963, the extraterritorial jurisdiction of a municipality overlapped the extraterritorial jurisdiction of one or more other municipalities, the governing bodies of the affected municipalities may apportion the overlapped area by a written agreement approved by an ordinance or a resolution adopted by the governing bodies.

(b) A municipality having a claim of extraterritorial jurisdiction to the overlapping area may bring an action as plaintiff in the district court of the judicial district in which the largest municipality having a claim to the area is located. The plaintiff municipality must name as a defendant each municipality having a claim of extraterritorial jurisdiction to the area and must request the court to apportion the area among the affected municipalities. In apportioning the area, the court shall consider population densities, patterns of growth, transportation, topography, and land use in the municipalities and the overlapping area. The area must be apportioned among the municipalities:

(c) An apportionment under this section must consider existing property lines. A tract of land or adjoining tracts of land that were under one ownership on August 23, 1963, and that do not exceed 160 acres may not be apportioned so as to be in the extraterritorial jurisdiction of more than one municipality unless the landowner gives written consent to that apportionment.
