Gov. Code, § 26806

(a) In counties having a population of 900,000 or over, the clerk of the court may employ as many foreign language interpreters as may be necessary to interpret in criminal cases in the superior court, and in the juvenile court within the county and to translate documents intended for filing in any civil or criminal action or proceeding or for recordation in the county recorder’s office.

(b) The clerk of the superior court, shall, when interpreters are needed, assign the interpreters so employed to interpret in criminal and juvenile cases in the superior court. When their services are needed, the clerk shall also assign interpreters so employed to interpret in criminal cases in municipal courts.

(c) The clerk of the court may also assign the interpreters so employed to interpret in civil cases in superior and municipal courts when their services are not required in criminal or juvenile cases and when so assigned, they shall collect from the litigants the fee fixed by the court and shall deposit the same in the county treasury.

(d) The interpreters so employed shall, when assigned to do so by the clerk of the court, translate documents to be recorded or to be filed in any civil or criminal action or proceeding. The fee to be collected for translating each such document shall be three dollars ($3) per folio for the first folio or part thereof, and two cents ($0.02) for each word thereafter. For preparing a carbon copy of such translation made at the time of preparing the original, the fee shall be twelve cents ($0.12) per folio or any part thereof. All such fees shall be deposited in the county treasury.
