La. Code Civ. Proc. art. 1445

When the testimony is fully transcribed the deposition shall be submitted to the witness for examination and shall be read to or by him, unless such examination and reading are waived by the witness and by the parties. Any changes in form or substance which the witness desires to make shall be entered upon the deposition by the officer with a statement of the reasons given by the witness for making them. The deposition shall then be signed by the witness unless the parties by stipulation waive the signing or the witness is ill or is absent from the parish where the deposition was taken or cannot be found or refuses to sign. If the deposition is not signed by the witness within thirty days of its submission to him, the officer shall sign it and state on the record the fact of the waiver or of the illness or absence of the witness or the fact of the refusal to sign together with the reason, if any, given therefor; and the deposition may then be used as fully as though signed unless on a motion to suppress under Article 1456 the court holds that the reasons given for the refusal to sign require rejection of the deposition in whole or in part. A video deposition does not have to comply with the requirements of reading and signing by the deponents.
