The writ runs in the name of “The State of Texas”. It is addressed to a person having another under restraint, or in his custody, describing, as near as may be, the name of the office, if any, of the person to whom it is directed, and the name of the person said to be detained. It shall fix the time and place of return, and be signed by the judge, or by the clerk with his seal, where issued by a court.Acts 1965, 59th Leg., vol. 2, p. 317, ch. 722.
