You would have to file a Motion to Set Aside the Default. Section 473 of the Code of Civil Procedure. The motion would have to be heard in the Courthouse where the action was filed (Lancaster), so dedicate some time to appearing there, probably a half day. If you hire an attorney to do this work for you, best to hire someone local in Lancaster to save on paying for travel time.
You need to file a motion under section 473 of the Code of Civil Procedure to vacate this judgment on the basis of this fraud, which you just found out about. You may need a lawyer to do this.

I have good news and bad news.
The bad news is that it is too late to file a motion to vacate default under Code of Civil Proecdure Section 473, which permits such motions to be filed up to six months after the default is entered.
The good news is that a default entered without valid service is void, and can be set aside on motion at any time.
While a proof of service “presumptively establishes the fact of proper service”, it “may be impeached and a lack of proper service shown by contradictory evidence”. Judicial Council Comment to Code of Civ. Proc. §417.10 “It has long been established that a false affidavit of service constitutes extrinsic fraud”, and is therefore void. “City of Los Angeles v. Morgan (1951) 105 Cal. App. 2d 726, 731. “[I]f a plaintiff chooses to obtain a judgment that is void for want of service of summons upon a defendant, he and his privies may not complain that the law did not accord to them a right which has never existed.” Id.
I have recently filed a motion to set aside a default judgment that was entered in the Los Angeles County Superior Court more than 10 years ago.
As in your case, this motion is based on the failure of the plaintiff to properly effect service of the summons and complaint on the correct person.
If I can be of help on this matter, please feel free to contact me.
I would strongly urge you to consult immediately with a litigator skilled in this area of the law.
