California Code, Welfare and Institutions Code - WIC § 212

There shall be no fee for filing a petition under this chapter nor shall any fees be charged by any public officer for his services in filing or serving papers or for the performance of any duty enjoined upon him by this chapter, except where the sheriff transports a person to a state institution. If the judge of the juvenile court orders that a ward or dependent child go to a state institution without being accompanied by an officer or that a ward or dependent child be taken to an institution by the probation officer of the county or parole officer of the institution or by some other suitable person, all expenses necessarily incurred therefor shall be allowed and paid in the same manner and from the same funds as such expenses would be allowed and paid were such transportation effected by the sheriff.
