Due Diligence Requirements

(You may find this page at this tiny URL: http://tinyurl.com/DueDilReq)

When a summons is served on an individual defendant, the law requires a "due diligent effort" at personal service before "substituted service" may be made. (See Code of Civil Procedure Sec. 415.20(a)) Each California Superior Court has different due diligence requirements. Some requirements are written in Local Rules that are subject to change without notice. Most county superior courts' due diligence rules and/or policies are unwritten and vary with each clerk that warms the default clerk's chair.

A process server needs to know BEFORE a substituted service is effected so that when it is served, it comports with the originating court's due diligence requirements. Many cases do not result in a default judgment against the defendant, but the court may not grant it if the substituted service did not comport with those requirements. The remedy is to re-serve it. The client and his or her client is pissed because of the rejected default, and the server will be asked to do it again for no additional charge, and it will make re-service harder because the defendant knows what both you and your car look like.

This site is one small attempt to gather up all the written rules from as many California Superior Courts that have them. We have only found a few, and the policies may have changed since they were posted. I can't figure out why these due diligence policies are unwritten and remain a peculiarly guarded secret. As a local process server who is familiar with the local court requirements, you can help us expand this process serving resource. Please notify us of any local due diligence requirements. You may do it publicly on the Process Server Institute Group Facebook page or anonymously via email to mailto: moc.etutitsnisp|ynot#moc.etutitsnisp|ynot. If the rule or policy you know or find and it is not in writing. it should be sourced with a name, position, and phone number if possible of the person who told you.

Generally, due diligence is:

  • 3 or 4 separate attempts on different days
  • 3 attempts on any day as long as they are spanned by 6 hours
  • 3 attempts on different days during a specified span of hours
  • Some require a weekend attempt

The due diligence rules vary widely between counties, and occasionally, within a county between branch courts. Some vary between the Limited and Unlimited Jurisdiction cases. Each Presiding Judge has the prerogative to dictate a change that, on the surface, seems arbitrary and peculiar. In most counties, a new Presiding Judge is rotated in every year, after a vote of all judges as a function of the court's administrative process. Some county courts have only one judge.

Local substituted service rules are strictly construed by local courts, especially when a local rule or presiding judge dictates it. If a substituted service diligence requirement is not met, and substantially differs from the court's specified time and "number of days" requirement, the court could reject the proof of service or a request to enter the default. The service previously performed could be invalidated by the court default clerk based upon these specific due diligence requirements.

Alternatively, the court could reconsider the clerk's rejection, but it would involve a special filing of an application or motion to the court for appropriate relief.
