Jerry and Juanita Hurt appeal an order denying their motion to vacate a default judgment. The judgment had been entered after they failed to respond to service by publication. The dispositive issue is not whether the original affidavit supporting publication was sufficient, but whether the trial court properly denied the Hurts' postjudgment CR 60(b) motion. We affirm.
The Hurts hired Frank Brennan to repair their fishing boat in October 1982. Brennan sent the repair bills to Angove Accounting, South Bend, in accordance with the Hurts' instructions. He wasn't paid, so Brennan filed a complaint for breach of contract in Pacific County Superior Court on June 29, 1983. The sheriff's return of service said: "deputy advises unable to serve—have left area—house appears empty—boat seized by U.S. Marshal."
Brennan then sought service by publication under RCW 4.28.100.1 His affidavit in support of publication averred *317"due and diligent inquiry of and among the former neighbors and associates of Defendants residing in Pacific County, ” and stated that the Hurts were residents who had left the state to avoid service of summons but had property in the state within the jurisdiction of the court. The summons was published and, when the Hurts failed to appear, an order of default and a judgment in the amount of $6,514.21 were entered against them.
Five years later, Brennan located the Hurts in Oregon and garnisheed their property there. The Hurts attempted to obliterate the writ of garnishment by attacking the Pacific County default judgment,2 claiming improper service by publication and, therefore, lack of personal jurisdiction. The Hurts' fundamental contention, one of substance, is that Brennan did not exercise due diligence in attempting to locate them before he effected service by publication. We disagree. The search was adequate as disclosed by the postjudgment record.
Two distinct issues are presented: (1) Was the original affidavit sufficient? We hold that it was not. (2) Was the trial court's ruling on the postjudgment CR 60(b) motion proper? We hold that it was.
Strict compliance with the statute is required for jurisdiction to attach when a summons is served by publication. Kent v. Lee, 52 Wn. App. 576, 579, 762 P.2d 24 (1988); Longview Fibre Co. v. Stokes, 52 Wn. App. 241, 244, 758 P.2d 1006 (1988); Painter v. Olney, 37 Wn. App. 424, 427, 680 P.2d 1066, review denied, 102 Wn.2d 1002 (1984). Affidavits supporting service by publication must set forth facts, not just conclusions, showing a reasonably diligent search; a simple averment that a defendant cannot be found within the state is insufficient. Kent v. Lee, 52 Wn. App. at 579-80. Here, the deputy's return of service and *318Brennan's original affidavit in support of service were insufficient for want of any facts showing a diligent search within the state of Washington. See Longview Fibre, 52 Wn. App. at 245; Kent, 52 Wn. App. at 579. Had jurisdiction been attacked before judgment (for example, during the 60-day period for answer allowed by CR 12(a)(2)), the trial court would have been required to dismiss.
A different standard applies, however, to post-judgment motions where, as here, the order of default or the judgment under attack recites service sufficient to confer jurisdiction. In such cases, a presumption of jurisdiction arises. Burns v. Stolze, 111 Wash. 392, 191 P. 642 (1920). That presumption can be overcome by a showing that publication was based on a defective affidavit, and the presumption will not insulate a judgment from attack if nothing else comes before the court after judgment to fortify the adequacy of the original search. See Burns v. Stolze, supra; Longview Fibre Co., 52 Wn. App. at 244.
That a factual inquiry would be in order in a post-judgment proceeding was recognized early in Gould v. White, 54 Wash. 394, 103 P. 460 (1909). Gould was an appeal from a decision in an attack on a previously entered tax foreclosure judgment. Appellants in Gould proved that the defendants in the tax foreclosure proceeding did not appear, were not personally served, and that the record showed only that a statutorily defective summons was published. The court stated:
This, in our opinion, made out a prima facie case in their behalf; the presumption in favor of jurisdiction was overcome, and the burden of proof shifted to the respondents to show that a valid service of process was made.
(Some italics ours.) Gould v. White, 54 Wash, at 397. The court stated that the time, place, and manner of publication were within the knowledge of respondents, and it "imposes no hardship on them to require them to produce such proofs." Gould, 54 Wash, at 397. We believe that Gould stands for the proposition that what appears prima facie to *319be defective service can be cured if attacked in a postjudgment proceeding by a factual showing that a proper basis for substitute service in fact existed.
Although an affidavit supporting substitute service is scrutinized strictly in a prejudgment proceeding, the issue before the court on a postjudgment CR 60(b) motion is: what in fact did the plaintiff do before seeking service by publication. Cf. Brenner v. Port of Bellingham, 53 Wn. App. 182, 187, 765 P.2d 1333 (1989) (after party presents factual evidence that affidavit supporting publication does not comply with statute, burden shifts to other party to show evidence that reasonable search was made). In our view, CR 60(b) speaks to substance, not form. See First Fed. Sav. & Loan Ass'n v. Ekanger, 93 Wn.2d 777, 781, 613 P.2d 129 (1980) (wherever possible, rules of civil procedure should be applied so substance will prevail over form).3
Here, Brennan filed five affidavits, in opposition to the motion to vacate, containing detailed evidence showing that the Hurts' boat was found abandoned in California; that the Hurts were in Texas during part of the time in 1983 that Brennan searched for them; that inquiries at Angove Accounting revealed no money with which to pay Brennan; and that Pacific County sheriff's deputies were attempting to serve the Hurts in three other legal matters during the 1983 period in question. We agree with the trial court that these affidavits in substance show that Brennan made "an honest and reasonable effort" to find the Hurts; the law requires no more. See Longview Fibre Co., 52 Wn. App. at 245; Painter v. Olney, 37 Wn. App. at 426-27. In view of *320Brennan's showing of what efforts in fact were made, the court properly denied the CR 60(b) motion to vacate.
Affirmed.
Alexander, C.J., concurs.
RCW 4.28.100 states in part: "When the defendant cannot be found within the state, and upon the filing of an affidavit of the plaintiff, his agent, or attorney, with the clerk of the court, stating that he believes that the defendant is not a resident of the state, or cannot be found therein, and that he has deposited a copy of the summons . . . and complaint in the post office, directed to the defendant at his place of residence, . . . and stating the existence of one of the cases hereinafter specified, the service may be made by publication of the summons, by the plaintiff or his attorney in any of the following cases:
"(2) When the defendant, being a resident of this state, has departed therefrom with intent to defraud his creditors, or to avoid service of summons, or keeps himself concealed therein with like intent;
"(3) When the defendant is not a resident of the state but has property therein and the court has jurisdiction of the subject of the actionj.]"
The Hurts' motion cites no supporting rule, but CR 60(b)(5) allows relief from a judgment if the judgment is void. Further, a default judgment entered without valid service is void and may be vacated when the want of jurisdiction is established, regardless of the passage of time. Brenner v. Port of Bellingham, 53 Wn. App. 182, 188, 765 P.2d 1333 (1989).
The dissent, at 322, disclaims "an overnice technical disputation as to the sufficiency of the original affidavit.” To the contrary, the dissent seems based entirely on technical disputation, for it would never allow an inquiry outside of the affidavit, whereas our analysis, unrefuted by the dissent's citations of authority, recognizes that the presumption of validity attaching to judgments distinguishes a prejudgment inquiry about service from a postjudgment inquiry, and that the latter properly focuses on what really happened rather than exclusively on what an affidavit says.
