You're going to have to have a better story than using the address where you were served as a mail drop to get out of this.
The fact that the lady getting your mail didn't give you the summons will be seen as a matter between you and the lady.
And if you are to be so lucky as to get the judgment set aside, you'll find that you are served right there in front of the court.
(I) was not properly served with the summons and complaint in this
matter. When a plaintiff fails to comply with the applicable statutes regarding service. a
judgment is void not merely voidable. See, County of San Diego v. Gorham (2010) 186
.1226 ("[a] judgment is void for lack of jurisdiction of the person
where there is no proper service of process on or appearance by a party to the
proceedings"). When a court lacks "fundamental jurisdiction" over the parties or subject
matter, any ensuing judgment is void and vulnerable to collateral or direct attack at any
time. Id. atp.1225; Rochin v. Pat Johnson Manufacturing Co. (1998) 67 Cal.App. th
1228,1?39, A judgment that is acquired in violation of due process rights is void and
must be set aside regardless of the merits of the underlying case. See, Perolta v. Heights
Medical Center, ftc. (1988) 485 U.S. 80, 86-87.) Prejudice is not a factor in setting
aside a void judgment or order. See, Sindler v. Brennan (2003) 105 Cal.App.4th 1350.
