Texas Code of Criminal Procedure - CRIM P Art. 11.27. How writ may be served and returned

The writ may be served by delivering a copy of the original to the person who is charged with having the party under restraint or in custody, and exhibiting the original, if demanded; if he refuse to receive it, he shall be informed verbally of the purport of the writ. If he refuses admittance to the person wishing to make the service, or conceals himself, a copy of the writ may be fixed upon some conspicuous part of the house where such person resides or conceals himself, or of the place where the prisoner is confined; and the person serving the writ of habeas corpus shall, in all cases, state fully, in his return, the manner and the time of the service of the writ.
