Legal Question in Real Estate Law in California

Yes. Even a husband and wife, living at the same address, must be served separately, each receiving his/her own copy of the summons, complaint and miscellaneous papers required to be served under local rules. Further, if the case has been proceeding for some time, a new defendant is entitled at some point to copies of motions, discovery, etc. - the complete file.

An officer or associate of a defendant may have entirely different legal interests, defenses, and a different law firm representing him or her.

That's assuming both the husband and the wife are named as defendants, of course.

I agree with Mr. Whipple. Each defendant that is named, including a defendant named previously as a "doe" defendant must be served with the summons and complaint.
