Louisiana Revised Statutes Tit. 15, § 43. Attorneys; restrictions on search warrants

A. The court may issue a subpoena when requested by either the defendant or the state, as provided for in Code of Criminal Procedure Articles 731 through 737, when an attorney is believed to be in possession of evidence of the commission of a crime by a client or a third party. In response to the subpoena, the attorney may assert any objection or privilege he may have under law, and the court shall, after hearing, grant or deny the objection or privilege in accordance with law.

B. A search warrant may issue, directing the seizure of property belonging to a client of an attorney which is in the possession of such attorney, or directing the search of the premises occupied by the attorney, on probable cause, established by affidavit, that the attorney or his employee has committed a criminal offense and that the search or seizure is directed toward obtaining evidence relative to that offense.

C. No search warrant shall issue directing the seizure of property belonging to a client of an attorney which is in the possession of an attorney, or directing the search of the premises occupied by the attorney, except under the circumstances provided for in Subsection B.
