A consumer who is a party may make a motion to quash or modify the subpoena duces tecum. Notice of motion shall be given to the witness and deposition officer prior to production. Any other consumer may serve on the subpoenaing party and the witness a written objection specifying grounds for prohibiting production of the records. No witness or deposition officer shall be required to produce personal records after receipt of a motion to quash the subpoena or an objection except upon court order or by agreement of the affected parties, witnesses and consumers. The subpoenaing party may make a motion to enforce the subpoena within 20 days of service of the written objection. The motion shall be accompanied by a declaration showing a reasonable and good faith attempt at informal resolution of the dispute between the subpoenaing party and the consumer. (CCP 1985.3 (g))
