Cal. Gov. Code § 25259.7

Any collection program that is operated by a court may apply to the presiding judge of the court for a discharge from accountability for any court-ordered debt or bail that it would otherwise be responsible for collecting, if the amount is too small to justify the cost of collection or the likelihood of collection does not warrant the expense involved. Responsibility for collection of court-ordered debt or bail shall be demonstrated by a written agreement between the county and the court. If the county is responsible for collecting court-ordered debt or bail, the county may transfer responsibility for discharging court-ordered debt or bail to the court by written agreement.
