OPINION
ANNE GARDNER, Justice.I. Introduction
Appellant Lease Finance Group, LLC (“LFG”) appeals a judgment of garnishment in favor of Appellees Randy Childers and Arlington Motor Cars USA1 against JP Morgan Chase Bank, N.A. (“Chase”).2 LFG contends in three issues that the trial court erred by denying LFG’s motion to set aside judgment and for new trial. We reverse and remand.
*123II. Factual and Procedural Background
AMC obtained a default judgment against LFG on May 2, 2008, in the amount of $24,500. On September 12, 2008, AMC filed an application for writ of garnishment naming Chase as garnishee and seeking to garnish funds held by Chase for LFG. The trial court issued the writ on September 15, 2008, and Chase was served with the writ on September 19, 2008. Chase filed its original answer on October 7, 2008. AMC and Chase then submitted an “agreed” judgment of garnishment to the trial court that was signed by counsel for AMC and Chase; the “agreed” judgment was not signed by LFG.
The trial court signed the judgment of garnishment on October 10, 2008. The judgment stated in the first paragraph:
The Court, having found that Judgment-Defendant [LFG] has been properly served with a copy of the Writ of Garnishment in accordance with Rule 663a and has failed to answer or to otherwise enter an appearance in this garnishment suit, is of the opinion that judgment should be rendered in accordance with the pleadings on file and as set forth herein.
Unaware of the October 10 judgment of garnishment, LFG filed its “Original Answer and Motion to Dissolve Writ of Garnishment” on October 24, 2008. LFG first learned of the October 10 judgment of garnishment at the hearing on its motion to dissolve on November 3, 2008.3
LFG thereafter filed a “Motion to Set Aside Judgment in Garnishment and for New Trial” on November 7, 2008, claiming it was not served in strict compliance with the rules of civil procedure. LFG submitted an affidavit, by its attorney, Mark Snyder, in support of the motion. Snyder stated in the affidavit that he told AMC’s attorney, Franklin Cram, on either October 6 or October 7, 2008, that he would not accept service of the writ of garnishment on behalf of LFG. Snyder also averred that he received a faxed letter from Cram on October 9, 2008. The October 9, 2008 letter enclosed a copy of an undated facsimile to LFG forwarding the writ of garnishment and application for writ of garnishment. Snyder further testified that he was unaware AMC had moved forward with the judgment of garnishment on October 10, 2008, and that he incorrectly calculated LFG’s answer day as if responding to service of citation rather than a writ of garnishment.
LFG attached a copy of the October 9, 2008 letter from Cram as an exhibit to Snyder’s affidavit. In the October 9, 2008 letter to Snyder, Cram stated: “I am enclosing the fax I sent [to LFG].” Although the enclosed facsimile included the writ of garnishment, the application for writ of garnishment, and an affidavit from Child-ers, the October 9, 2008 letter did not set forth the date on which AMC sent the facsimile to LFG. Further, the enclosed facsimile is not dated and does not include facsimile-transmission information indicating when AMC sent it; the only facsimile-transmission information relates to the facsimile sent by Cram to Snyder on October 9, 2008, the day before the trial court signed the agreed judgment.
The trial court conducted a hearing on LFG’s Motion to Set Aside Judgment in Garnishment and for New Trial on December 5, 2008. Although LFG contested notice under rule 663a in its motion, AMC *124did not offer evidence of notice at the hearing or in a written response.4 The trial court orally denied LFG’s motion at the end of the hearing,5 and this appeal followed.
III. Service of Writ of Garnishment on LFG
In its first and second issues, LFG argues the trial court erred by denying its motion to set aside judgment and for new trial because there is no evidence in the record that LFG was properly served with notice of the writ of garnishment, or, alternatively, the notice LFG received was untimely.6 In response, AMC contends the trial court correctly denied LFG’s motion because the judgment recites notice was proper under rule 663a, there is no minimum notice required under rule 663a, and LFG failed to prove that it was not served in compliance with rule 663a.7
A. Standard of Review
A trial court’s order denying a motion to set aside a default judgment or for new trial is reviewed under an abuse of discretion standard. Strackbein v. Prewitt, 671 S.W.2d 37, 38 (Tex.1984); Martinez v. Martinez, 157 S.W.3d 467, 469 (Tex.App.-Houston [14th Dist.] 2004, no pet.). The trial court abuses its discretion if it acts without reference to any guiding rules or principles. Goode v. Shoukfeh, 943 S.W.2d 441, 446 (Tex.1997).
B. Applicable Law
“A writ of garnishment impounds the alleged money, property, or credits of the debtor.” Mendoza v. Luke Fruia Invs., Inc., 962 S.W.2d 650, 651 (Tex.App.-Corpus Christi 1998, no pet.) (citing Beggs v. Fite, 130 Tex. 46, 52, 106 S.W.2d 1039, 1042 (1937)). “The writ of garnishment affords a harsh remedy. It was not known to the common law, but is purely statutory.” Walnut Equip. Leasing Co. v. J-V Dirt & Loam, 907 S.W.2d 912, 914 (Tex.App.-Austin 1995, writ denied). “For this reason, garnishment proceedings cannot be sustained unless they strictly conform to the statutory requirements and related rules.” Id. Specifically, “[t]he garnishor must strictly comply with the requirement that it serve the debtor, and its failure to comply is not a mere irregularity.” Id. “Without proper service of the writ on the debtor, no control or custody of his property can be gained by his answer.” Mendoza, 962 S.W.2d at 652.
Rule 663a of the rules of civil procedure states, in relevant part: “The defendant shall be served in any manner prescribed for service of citation or as provided in Rule 21a with a copy of the writ of garnishment, the application, accompanying affidavits and orders of the court as soon as practicable following the service of the writ.” Tex.R. Civ. P. 663a; *125see also Hering v. Norbanco Austin I, Ltd., 735 S.W.2d 638, 641 (Tex.App.-Austin 1987, writ denied). Actual knowledge or a voluntary appearance by the debtor is insufficient and does not waive rule 663a’s requirement of service of the writ. Walnut Equip. Leasing Co., 907 S.W.2d at 914; Hering, 735 S.W.2d at 642; see also Requena v. Salomon Smith Barney, Inc., No. 01-00-00783-CV, 2002 WL 356696, at *3 (Tex.App.-Houston [1st Dist.] March 7, 2002, no pet.); Mendoza, 962 S.W.2d at 652. Although rule 663a does not entitle a debtor to a minimum of twenty days’ notice as with service of an original petition, Mullins v. Main Bank & Trust, 592 S.W.2d 24, 26 (Tex.Civ.App.-Beaumont 1979, no writ), the debtor does have the right to service of the writ of garnishment and related documents “as soon as practicable following the service of the writ” on the garnishee. Tex.R. Civ. P. 663a.
C. Analysis
LFG argues the trial court erred by denying its motion to set aside and for new trial because there is no evidence in the record that LFG was served with notice of the writ of garnishment, or, alternatively, that the notice LFG received was untimely. Before addressing LFG’s issues, we must first address AMC’s contentions that there is sufficient evidence of service because the judgment recites service was proper under rule 663a, that there is no minimum notice required under rule 663a, and that LFG had the burden to prove it was not properly seived under rule 663a.
1. No Presumption of Service from Recitation in Judgment
AMC contends there is sufficient evidence of sendee because the judgment recites LFG was served in compliance with rule 663a. Although a recitation of due notice in a judgment is some, but not conclusive, evidence of proper notice of trial settings and hearings, see Osborn v. Osborn, 961 S.W.2d 408, 411 (Tex.App.-Houston [1st Dist.] 1997, pet. denied), the rule does not apply to default judgments. In an attack upon a default judgment, a recitation of - due service in the judgment does not lead to a presumption of due service. Morris v. Zesati, 162 S.W.3d 669, 671 (Tex.App.-El Paso 2005, no pet.) (citing McKanna v. Edgar, 388 S.W.2d 927, 929 (Tex.1965)). Instead, the plaintiff must “prove that the defendant was served in the required manner.” Id.
Here, the judgment in garnishment is analogous to a default judgment because the trial court signed the judgment in garnishment before LFG answered or otherwise appeared. See Tex.R. Civ. P. 239 (providing trial court may render default judgment on the pleadings against a defendant that has not filed an answer); see also Crowe v. Ware, No. 05-96-01294-CV, 1998 WL 258398, at *1-2 (Tex.App.-Dallas May 22, 1998, no pet.) (treating judgment in garnishment as default judgment on appeal by judgment debtor claiming lack of service under rule 663a). While the judgment debtor is not a necessary party to the garnishment action, the rules require that he be served under rule 663a. Hering, 735 S.W.2d at 642 (citing Horse-ley, Collecting on Judgments (State Bar of Texas Professional Development Program 1981)).
“Rule 663a is unambiguous in its requirement that the debtor be given notice of the garnishment and of his rights to regain his property.” Id. at 641. “[Gjarnishment proceedings cannot be sustained unless they strictly conform to the statutory requirements and related rules.” Walnut Equip. Leasing Co., 907 S.W.2d at 914. “[N]o control or custody of [a judgment debtor’s] property can be gained by his answer” without proper service of the writ. Mendoza, 962 S.W.2d at 652. The *126creditor’s failure to strictly comply with the pertinent rules “is fatal to its judgment in the garnishment action.” Hering, 735 S.W.2d at 641 (emphasis in original). We believe the rule applicable to default judgments should apply to judgments in garnishment and hold that a recitation of due service in a judgment in garnishment does not lead to a presumption of due service. See generally Morris, 162 S.W.3d at 671. In this case, LFG attacked the default judgment in garnishment by contending AMC did not serve LFG in compliance with rule 663a. Thus, even though the judgment in garnishment recites that LFG was properly served under rule 663a, there is no presumption of valid service.
2. Rule 663a Requires Service As Soon As Practicable
AMC next contends rule 663a does not establish a prescribed period in which a garnishor must serve a writ of garnishment on the debtor. We disagree. Rule 663a specifically requires service on the judgment debtor “as soon as practicable following service of the writ” on the garnishee. Tex.R. Civ. P. 663a. “As soon as practicable” is not susceptible to a definitive definition equally applicable in all cases, but we note that a fifteen-day delay before serving the debtor does not satisfy the strict requirements of rule 663a. See Requena, 2002 WL 356696, at *4. Thus, we reject AMC’s contention that rule 663a does not establish a prescribed period in which the garnishor must serve the debtor.
3. AMC had the Burden to Prove Proper Service
AMC also argues the trial court correctly denied LFG’s motion to set aside judgment and for new trial because LFG failed to prove it was not served in compliance with rule 663a. In doing so, AMC ineor-rectly assumes LFG had the burden to prove it was not properly served under the rule.
Rule 663a permits service on the debtor “as provided in Rule 21a.” Tex.R. Civ. P. 663a. Under rule 21a, all notices, other than citation, may be served by delivering a copy to the party either in person, by agent, or by certified or registered mail to the party’s last known address or by fax to the party’s current telecopier address. Tex.R. Civ. P. 21a. “A certificate by a party or an attorney of record, or the return of an officer, or the affidavit of any person showing service of a notice shall be prima facie evidence of the fact of service.” Id. Rule 21a further provides that “the party or attorney of record shall certify to the court compliance with this rule in writing over signature and on the filed instrument.” Id. (emphasis added); see also Crowe, 1998 WL 258398, at *1 (noting certificate of service on file at time of garnishment judgment established service by regular mail although certified mail was returned unopened).
However, where the record does not contain a certificate of service, an officer’s return, or an affidavit showing service of notice, there is no presumption of receipt, and the party contending it properly sent notice has the burden of proving proper notice under rule 21a. Mathis v. Lockwood, 166 S.W.3d 743, 745 (Tex.2005); see Crowe, 1998 WL 258398, at *2 (citing Walnut, 907 S.W.2d at 915 and Hering, 735 S.W.2d at 642 and holding rule 663a requires proof that debtor was properly served under rule 21a). Because AMC did not file a certificate of service, an officer’s return, or an affidavit showing service, AMC had the burden to prove proper service under rule 21a. Mathis, 166 S.W.3d at 745.8
*1274. AMC Did Not Prove It Served LFG As Soon As Practicable
We next consider whether the record contains sufficient evidence that AMC served LFG in compliance with rule 663a. It is undisputed that AMC did not serve LFG in a manner prescribed for service of citation. Thus, if AMC properly served LFG, AMC must have done so “as provided in Rule 21a.” See Tex.R. Civ. P. 663a. In this case, the combination of rules 21a and 663a required AMC to deliver a copy of the writ of garnishment to either LFG (or its duly authorized agent) or LFG’s attorney of record as soon as practicable after service on the garnishee on September 19, 2008. See Tex.R. Civ. P. 21a, 663a.
First, AMC has not shown that it served LFG by serving LFG or its duly authorized agent as soon as practicable. The only evidence of service in the record is the October 9, 2008 letter and its enclosed facsimile. The October 9, 2008 letter states, “I am enclosing the fax I sent to [LFG],” but it does not set forth the date AMC claims it sent the enclosed facsimile to LFG. The enclosed facsimile is not dated, and it does not include any facsimile-transmission information to indicate when AMC sent it. While the lack of a date on the facsimile does not necessarily defeat the fact of service under rule 21a, the lack of a date does mean AMC has not shown that it served LFG “as soon as practicable” as required by rule 663a. See Tex.R. Civ. P. 663a.
Second, AMC has not shown that it served LFG as soon as practicable through LFG’s attorney of record. The record reflects- AMC’s attorney sent the undated facsimile as an enclosure to the October 9, 2008 letter to Snyder. Assuming without deciding that Snyder was LFG’s attorney of record on October 9, 2008,9 we note that the garnishee, Chase, was served on September 19, 2008, and that the trial court signed the judgment in garnishment on October 10, 2008. Thus, AMC served a copy of the writ of garnishment on LFG’s attorney twenty days after service on the garnishee and one day before the trial court signed the judgment in garnishment. However, nothing in the record explains the twenty-day delay in service. Under these circumstances, we hold AMC failed to prove that it served LFG through its attorney “as soon as practicable” as' required by rule 663a. Tex.R. Civ. P. 663a; see also Requena, 2002 WL 356696, *3^4 (holding garnishor did not serve judgment debtor “as soon as practicable” where gar-nishor could have reasonably served judgment debtor fifteen days before it did).
AMC’s failure to prove it strictly complied with rule 663a is fatal to its judgment in garnishment. “It has long been the law of this State that if a judgment-creditor intends to avail himself of the State’s aid in effecting a deprivation of property, he must strictly comply with the pertinent rules.” Hering, 735 S.W.2d at 641. Because the record does not reflect service of *128the writ of garnishment on LFG as soon as practicable in compliance with rule 663a, the trial court abused its discretion in denying LFG’s motion to set aside and for new trial. We sustain LFG’s first and second issues.10
IV. Conclusion
Having sustained LFG’s first and second issues, we reverse the trial court’s judgment and remand for further proceedings consistent with this opinion.
WALKER, J., filed a dissenting opinion.
. We will collectively refer to Appellees Child-ers and Arlington Motor Cars USA as "AMC.”
. Chase, the garnishee in the trial court, is an appellee in this case but did not file a brief.
. There is no reporter's record from the November 3 hearing or written order on LFG’s motion to dissolve writ of garnishment.
However, the trial court’s docket sheet indicates the trial court denied LFG’s motion to dissolve writ of garnishment.
. AMC filed a written response to LFG's motion on the day of the hearing, but AMC did not submit any evidence with the response.
. The trial court stated: "I’m going to deny the motion for new trial and let the parties proceed on the bill of review question.” The bill of review proceeding filed by LFG is not before this court, and we express no opinion on the merits of that proceeding.
. We address LFG's first and second issues together because they involve the same questions of law and fact.
.AMC also argues LFG waived its notice arguments by not raising them in its motion to set aside and for new trial. We disagree. LFG specifically stated on the first page of its motion that a "judgment in garnishment is subject to being set aside” where the "judgment debtor has not been give[n] proper notice of a garnishment pursuant to Rule 663a of the Texas Rules of Civil Procedure” and that "[t]he notice allegedly given to [LFG] did not comply with Rule 663a.”
. In this appeal from the trial court’s denial of LFG's motion to set aside judgment and for *127new trial, we express no opinion as to which party bears the burden of proof on a motion under rule 664a. See Tex.R. Civ. P. 664a (permitting trial court to dissolve or modify writ of garnishment upon sworn motion by judgment debtor or other intervening party claiming interest in garnished property). Our holding applies only to proof of timely service under rule 663a “as provided in Rule 21a” in the absence of a certificate of service, an officer’s return, or other prima facie proof of service. See Tex.R. Civ. P. 663¾ 21a.
. It is unclear from the record whether LFG, as of October 9, 2008, had retained Snyder to represent LFG in the garnishment action or whether LFG had only retained Snyder to file a bill of review to attack the underlying judgment. Because it does not affect our holding, we assume Snyder represented LFG in the garnishment action as of October 9, 2008.
. Because we sustain LFG’s first and second issues and hold AMC did not serve LFG in compliance with rule 663a, we need not address LFG's third issue in which it contends it satisfied the second and third elements of the Craddock test for overturning default judgments. See Lopez v. Lopez, 757 S.W.2d 721, 723 (Tex.1988) (where there is no actual or constructive notice of a trial setting, a party need not show “he had a meritorious defense as a condition to granting his motion for new trial”); In re Marriage of Runberg, 159 S.W.3d 194, 200 (Tex.App.-Amarillo 2005, no pet.) (applying Lopez to both the second and third elements of the Craddock test).
