Cal. Civ. Proc. Code § 1017 — Notices, and Filing and Service of Papers

Any summons, writ, or order in any civil suit or proceeding, and all other papers requiring service, may be transmitted by telegraph for service in any place, and the telegraphic copy of such writ, or order, or paper so transmitted, may be served or executed by the officer or person to whom it is sent for that purpose, and returned by him, if any return be requisite, in the same manner, and with the same force and effect in all respects, as the original thereof might be if delivered to him, and the officer or person serving or executing the same has the same authority, and is subject to the same liabilities, as if the copy were the original. The original, when a writ or order, must also be filed in the Court from which it was issued, and a certified copy thereof must be preserved in the telegraph office from which it was sent. In sending it, either the original or the certified copy may be used by the operator for that purpose. Whenever any document to be sent by telegraph bears a seal, either private or official, it is not necessary for the operator, in sending the same, to telegraph a description of the seal, or any words or device thereon, but the same may be expressed in the telegraphic copy of the letters “L. S.,” or by the word “seal.”
