California Civil Code section 418.10 allows a defendant to file a motion to quash service of process. A defendant in an unlawful detainer action may still file a motion to quash service if process was not served in a statutorily authorized manner, even though he has actual notice of the lawsuit (i.e. received the summons and complaint). See Schering Corp. v. Super. Ct. (Ingraham), 52 Cal. App. 3d 737, 741 (1975). This motion is a pleading, so there is no judicial council form like there is for discovery. The defendant must also attach a proof of service when he files it. Here is an example.
Below is an example of a motion to quash service of process in a non-unlawful detainer case, note the differences:
