Full Text of Rule 3.221
Plain-English Summary
Rule 3.221 puts information about mediation, arbitration, and other out-of-court options in front of litigants at the very start of a case. When a plaintiff files a general civil complaint, the court must make available an ADR information package explaining, at minimum, what the main ADR processes look like, what programs that particular court offers, and how to reach the people who run them. Courts in counties that fund local dispute resolution programs through the Dispute Resolution Programs Act must also point litigants toward those programs, and every package includes a stipulation form parties can sign if they want to try ADR.
Courts can post the package on their website, but only as a backup — paper copies still have to be available at the clerk's office for anyone who needs one. The heavier obligation falls on the plaintiff, who must serve a copy of the package on every defendant along with the complaint, and on any cross-complainant, who must do the same for any new party pulled into the case by a cross-complaint.
Frequently Asked Questions
What is the ADR information package a California court must provide?
It is a set of materials, required by Rule 3.221(a), describing the main forms of alternative dispute resolution, the specific programs that court offers, and how to reach the staff who handle ADR questions.
Does the plaintiff have to send the ADR package to the defendant?
Yes. Rule 3.221(c) requires the plaintiff to serve a copy of the ADR information package on each defendant along with the complaint in general civil cases.
Does a cross-complainant have the same obligation?
Yes. A cross-complainant must serve the ADR information package on any new party brought into the case by the cross-complaint, at the same time as the cross-complaint itself.
Can a court just put the ADR package online instead of handing out paper copies?
No. A court may post the package on its website, but Rule 3.221(b) still requires paper copies to remain available in the clerk's office.
