Texas Code of Criminal Procedure - CRIM P Art. 16.09. Testimony reduced to writing

The testimony of each witness shall be reduced to writing by or under the direction of the magistrate, and shall then be read over to the witness, or he may read it over himself. Such corrections shall be made in the same as the witness may direct; and he shall then sign the same by affixing thereto his name or mark. All the testimony thus taken shall be certified to by the magistrate. In lieu of the above provision, a statement of facts authenticated by State and defense counsel and approved by the presiding magistrate may be used to preserve the testimony of witnesses.
