REYNOLDS, Chief Justice.
Texas Farmers Insurance Company secured declarations, via summary judgment, that it had no duty to defend Orlando Rodriquez and Lydia Rodriquez under its insurance policy issued to them, or to indemnify or pay on their behalf any sums they were obligated to pay David A. Ortega and Rita Ortega for claims resulting in a default judgment against the Rodriquezes. The Rodri-quezes and the Ortegas contend, with five points of error, that questions of fact exist to vitiate the summary judgment. Based upon the rationale and authorities expressed, we will affirm the judgment.
The events underlying this appeal began on 5 May 1990, when the Rodriquezes’ dog, Bozo, bit mailman David Ortega on the arm.1 Complicated procedural maneuvering followed when, after unsuccessful settlement negotiations, attorney Mark Fitzgerald filed, on 4 May 1992, in the 47th District Court of Potter County, a lawsuit on behalf of the Ortegas, seeking to recover from the Rodri-quezes for David’s injuries and Rita’s loss of consortium (the Potter suit). Reciting the Rodriquezes’ failure to appear and answer despite having been “duly and legally cited to appear and answer,” the court entered a 4 June 1992 default judgment against them, awarding David $1,500,000 and Rita $150,000, with both awards bearing pre- and post-judgment interest at 10% per annum.
The Rodriquezes had a homeowners policy of insurance with Farmers (the policy), designed to indemnify them up to $100,000 from liability for, among other things, injuries resulting from Bozo’s penchant for biting. Previously, Farmers had indemnified the Rodriquezes pursuant to the policy provisions for several other incidents involving Bozo’s proclivity to bite mailmen and others, and Farmers, through its adjustor Henry Honea, had conducted settlement negotia[502]*502tions with Fitzgerald regarding the Ortegas’ claims.
The policy provided that if a lawsuit, such as the Potter suit, was filed against the Rod-riquezes, Farmers would provide an attorney to defend them against the claims, conditioned upon its receipt of proper notice of the lawsuit. However, in this instance, Farmers maintained that it did not receive proper notice of the Potter suit, and thus it failed to provide the Rodriquezes a defense before the default judgment was taken against them.
Upon learning of the default judgment, Farmers hired attorney Patrick Mosley to prepare an answer to the Potter suit, and a motion for new trial to have the default judgment set aside upon the assertion of defective service of citation on the Rodri-quezes. Mosley filed an answer on 9 June 1992, but refused to file a motion for new trial, stating that it would not be in the Rodriquezes’ best interest to do so.
Mosley believed this to be so because, on 18 June 1992, the Rodriquezes and the Orte-gas executed an agreement, filed as part of the record in the Potter suit, whereby the Ortegas agreed not to execute the default judgment against the Rodriquezes in exchange for 90% of all sums owed to, and claims held by, the Rodriquezes pursuant to their policy of insurance with “Fire Insurance Exchange or any of the Farmers Insurance Group of Companies.” Based upon this agreement, Mosley opined the Rodriquezes were protected from personal liability beyond the limits of the policy, and filing a motion for new trial would expose them to the possibility of personal liability if a new judgment were entered for an amount in excess of the policy limits.
At Farmers’s request, Wyatt Brooks entered his appearance as attorney for the Rodriquezes and filed a motion for new trial, purportedly on their behalf, based upon assertions that the failure to answer was not a result of conscious indifference, but of accident or mistake, and that the Rodriquezes had a meritorious defense to the Ortegas’ claims. Believing the motion for new trial to be a violation of their agreement with the Ortegas, the Rodriquezes furnished affidavits to the Ortegas’ attorney stating that Brooks was not authorized to file the motion on their behalf.2
Attorney Greg Enos, after filing his appearance as “attorney in charge” on behalf of the Ortegas, moved to require Brooks to show by what authority he filed pleadings on behalf of the Rodriquezes. Resultantly, the motion for new trial, and all filings signed by Brooks, including the cost bond for an appeal, were stricken upon the trial court’s determination that he had no authority to act on behalf of the Rodriquezes.3
The action from which this appeal arose was initiated by Farmers’s petition for declaratory relief filed on 6 August 1992 in the 287th District Court of Lubbock County (the underlying suit). Naming the Rodriquezes and the Ortegas as defendants, Farmers asserted that the Rodriquezes failed to provide notice of the Ortegas’ suit against them, and sought a declaration of the rights of the parties under the terms of the policy.
On 18 September 1992, the Rodriquezes and the Ortegas moved to have the venue of the underlying suit moved to Starr County. The motion was founded upon allegations that a prior suit between the same parties and involving the same issues was filed in Starr County on 10 July 1992 (the Starr suit), and the two should be consolidated. In support of the allegation, they attached a copy of an uncertified document entitled “Plaintiffs Second Amended Original Petition,” whose style included a Starr County heading, but which bore no file-stamp by the clerk of the court, no original signature of an attorney, no date on the certificate of service, and no reference to the date of filing of the original petition.
[503]*503Subject to their efforts to have the venue of the underlying suit moved to Starr County, the Rodriquezes and the Ortegas filed a counterclaim contending Henry Honea, an adjustor for Farmers, had negotiated with Fitzgerald and had notice of his intention to file suit if no settlement could be reached.4 Alleging Honea had the opportunity to settle the claim for $25,000, but failed to do so, the Rodriquezes and the Ortegas sought damages for Farmers’s negligence and gross negligence in failing to properly investigate, defend, and settle the claim against their insured as required by G.A Stowers Furniture Co. v. American Indemnity Co., 15 S.W.2d 544 (Tex.Comm’n App.1929, holding approved), and Ranger County Mut. Ins. Co. v. Guin, 723 S.W.2d 656 (Tex.1987).
Additionally, the Rodriquezes and the Ortegas moved to either dismiss or abate the underlying suit pending the outcome of the Starr suit. They did not request a hearing of this motion upon its filing, and a hearing was not requested until five months later.
On 28 September 1992, the trial court ordered the underlying suit transferred to Starr County. However, on 25 February 1993, the parties agreed to the return of the suit to the Lubbock court, because the “cause was mistakenly transferred to Starr County since the requisite hearing and notice were not provided.” See Tex.R.Civ.P. 87. Two hours before the filing of the agreement, the Rodriquezes and the Ortegas requested a hearing on their motion to dismiss or abate the underlying suit, but no setting was then made, and the underlying suit remained dormant until 30 June 1994.
Alleging the Rodriquezes were not legally obligated to pay the default judgment, Farmers filed its first amended original petition for declaratory relief. Attached as an exhibit to the petition was an agreement between the Rodriquezes and the Ortegas, by which they declared their prior agreement null and void, and provided that the Rodriquezes assigned to the Ortegas 80% “of any claims and causes of action” they might have against Farmers or any of its affiliates. Farmers reasserted that the Rodriquezes failed to notify it of the Potter suit, and asserted that Farmers had no liability under the policy because the Rodriquezes were not properly served with citation of the Potter suit. Farmers concluded its duty to defend was not invoked, and that the Rodriquezes had failed to cooperate as required by the policy, which precluded coverage under the policy.
Farmers moved for summary judgment on the grounds that (1) the Rodriquezes were not properly served and, therefore, the default judgment was illegitimate; (2) the Rod-riquezes failed to cooperate with their insurer and were in collusion with the Ortegas, by which they violated conditions of coverage; and (3) Farmers was under no duty to pay the default judgment. Farmers provided over 480 pages of documented summary judgment proof in support of its contention of entitlement to judgment as a matter of law.
In response, the Rodriquezes and the Ortegas represented there were questions of fact concerning whether (1) Farmers breached the insurance contract first, which in turn excused the Rodriquezes’ cooperation; (2) the Rodriquezes in fact breached the cooperation clause; (3) the default judgment was void; (4) Farmers waived any policy defenses and was estopped from asserting them; and (5) the agreement between the Ortegas and the Rodriquezes precluded any duty by Farmers to pay the default judgment. Further, they pleaded that Farmers’s motion ignored their counterclaim, and that venue was not proper in Lubbock because the underlying suit involved the same issues “now pending in Potter county.”5 As support, they offered the affidavits of attorneys John [504]*504Judge, Fitzgerald and Enos, and excerpts from the depositions of Honea and Mosley.
On 5 August 1994, the Rodriquezes and the Ortegas filed an amended motion to dismiss or abate the underlying suit. In support of their contention that the Starr suit was filed prior in time and involved the same parties and issues, they attached copies of documents entitled “Plaintiffs Fourth Amended Original Petition,” and “Defendants’ Motion to Transfer Venue and Original Answer,” the styles of which included a Starr County heading, but neither of which bore a file-stamp by the clerk of the court or were certified to be copies of original documents.
On the same date, the Rodriquezes and the Ortegas also filed an amended motion to transfer venue and an answer subject to that motion, attaching the same “Plaintiffs Fourth Amended Original Petition” in support. They asked only for a hearing on the motion to dismiss or abate, and not on the motion to transfer venue.
Responding to the amended motion to dismiss or abate the underlying suit, Farmers replied that procedural defects and a lack of identical issues precluded the relief sought. Challenging Judge’s and Fitzgerald’s affidavits as competent summary judgment evidence, Farmers objected to the use of the affidavits as evidence to support the Rodri-quezes’ and the Ortegas’ response.
By its 5 October 1994 judgment, the trial court denied the motion to dismiss or abate the underlying suit, sustained Farmers’s objections to the affidavits, and decreed Farmers had no duty to defend the Potter suit prior to, and had no duty to pay, the default judgment, and that the Rodriquezes had no coverage under the policy for the Potter suit. On 6 January 1995, the court severed the Rodriquezes’ and the Ortegas’ counterclaim, making the 5 October 1994 judgment final and appealable, and mooting the Rodri-quezes’ and the Ortegas’ appellate contention, offered by their post-submission letter brief, of a fact issue regarding the disposal of their Stowers counterclaim. Hargrove v. Insurance Inv. Corporation, 142 Tex. 111, 176 S.W.2d 744, 747 (1944).
By their perfected appeal, the Rodriquezes and the Ortegas contend the trial court erred in (1) denying their motion to dismiss or abate the underlying suit, (2) sustaining Farmers’s objections to the Judge and Fitzgerald affidavits, (3) decreeing Farmers had no duty to defend the Rodriquezes prior to the default judgment (4) nor any duty to indemnify them from that judgment, and (5) decreeing that the Rodriquezes had no coverage under the policy. We will address the contentions of error in logical order.
Pursuant to rule 166a(e), Texas Rules of Civil Procedure, a summary judgment is proper only when a movant establishes there is no genuine issue of material fact and the movant is entitled to judgment as a matter of law. Gibbs v. General Motors Corporation, 450 S.W.2d 827, 828-29 (Tex.1970). Once the movant has established a right to summary judgment, the non-movant assumes the burden to respond and present any issues which would preclude summary judgment. City of Houston v. Clear Creek Basin Authority, 589 S.W.2d 671, 678 (Tex.1979).
When reviewing the granting of a motion for summary judgment, we do not view the evidence in the light most favorable to the judgment of the trial court; rather, we follow the standards mandated by the Supreme Court in this language:
1. The movant for summary judgment has the burden of showing that there is no genuine issue of material fact and that it is entitled to judgment as a matter of law.
2. In deciding whether there is a disputed material fact issue precluding summary judgment, evidence favorable to the non-movant will be taken as true.
3. Every reasonable inference must be indulged in favor of the non-movant and any doubt resolved in its favor.
Nixon v. Mr. Property Management, 690 S.W.2d 546, 548-49 (Tex.1985).
Initially, the Rodriquezes and the Ortegas contend the trial court erred in not abating the underlying suit because the Starr suit was filed prior in time and involved the same parties and issues. In this regard, it is well settled that the court in which suit is [505]*505first filed acquires dominant jurisdiction to the exclusion of other coordinate courts, and abatement is only proper in deference to a suit which has dominant jurisdiction. Curtis v. Gibbs, 511 S.W.2d 268, 267 (Tex.1974). By submitting the abatement issue in their response to Farmers’s motion for summary judgment, the Rodriquezes and the Ortegas contended, and on appeal contend, that the predominance of the Starr suit created a question of fact. To raise the fact issue of such contention, it was incumbent upon them to present competent summary judgment evidence which would raise the fact of the predominance of the Starr suit. Allen v. Western Alliance Insurance Co., 162 Tex. 572, 349 S.W.2d 590, 594 (Tex.1961).
Although the Rodriquezes and the Ortegas alleged the Starr suit was filed on 10 July 1992, prior to the 6 August 1992 filing of the underlying suit, their pleadings did not constitute summary judgment proof; they must have presented summary judgment proof to establish a fact issue. City of Houston v. Clear Creek Basin Authority, 589 S.W.2d at 678. The only proof offered consisted of the uncertified copies of pleadings purportedly filed in the Starr suit; however, absent the certification of the copies required by rule 166a(f), supra, the copies were not, as they must be, in a form admissible at a conventional trial, Gibralter Sav. Ass’n v. Martin, 784 S.W.2d 555, 556 (Tex.App.—Amarillo 1990, writ denied), and showed nothing more than that they were drafted. As a result, the Rodriquezes and the Ortegas are in the position of offering no evidence to show the existence of the genuine issue of fact of the predominance of the Starr suit. Town North Nat. Bank v. Broaddus, 569 S.W.2d 489, 494 (Tex.1978).
We are not persuaded by the Rodriquezes’ and the Ortegas’ post-submission contention, in letter brief form, that Farmers’s response to their motion to dismiss or abate conceded that another suit was pending in Potter County and, hence, amounted to a “judicial admission.” Farmers’s response did not concede that the Starr suit was prior in time to the underlying suit, nor that it involved the same issues and parties; in fact, Farmers contradicted the contention by its response. The first point of error is overruled.
By their second point, the Rodriquezes and the Ortegas complain of the trial court’s sus-tainment of Farmers’s objections to Judge’s and Fitzgerald’s affidavits and the exclusion of the affidavits from consideration as summary judgment evidence. Despite the heterogeneity of Farmers’s objections to the trial court vis-a-vis its appellate arguments, we cannot fault the trial court for excluding the affidavits from consideration as summary judgment evidence.
To establish his qualifications as an expert, Judge averred that he was a licensed attorney, familiar with personal injury suits, including those involving attacks by domestic pets, and that he had reviewed a specified list of documents relative to the Lubbock, Starr and Potter suits. Judge then opined that Farmers negligently handled the settlement negotiations in the Potter suit; that Farmers breached the insurance contract in its failure to defend the Rodriquezes in the Potter suit; and that the Rodriquezes, “at all times cooperated with Farmers and did not breach the insurance contract.”
Judge was not one of the attorneys involved in the Potter suit litigation, nor in the underlying suit; instead, his opinions were based upon his review of the documents listed in the exhibit to his affidavit. However, those records were not attached to the affidavit and several of them do not appear anywhere in the summary judgment evidence.
At the hearing on the motion for summary judgment, Farmers objected that Judge’s opinions were “global and concluso-ry” and would be inadmissible at trial, and that the affidavit failed to recite a proper oath. Judge averred that he was personally acquainted with the facts stated in his affidavit, but because he did not state those facts were true, the trial court correctly excluded his affidavit from consideration. Humphreys v. Caldwell, 888 S.W.2d 469, 470-71 (Tex.1994). However, Farmers’s appellate objection to Judge’s affidavit is that it is substantively defective because it fails to contain certified copies of the documents upon which he relied in formulating his opinions.
[506]*506The Rodriquezes and the Ortegas are correct that Farmers’s objections to the trial court as to the form of Judge’s affidavit do not comport with its appellate complaint as to the substance of the affidavits. Nevertheless, when the appellate complaint relates to the substance of the affidavit, it is not necessary that the objection was pointed out to the trial court, because there is no requirement of an opportunity to amend upon such a complaint. Bell v. Moores, 832 S.W.2d 749, 756 (Tex.App.—Houston [14th Dist.] 1992, writ denied). Failure to attach copies of the documents was a substantive defect which may be raised for the first time on appeal. Ceballos v. El Paso Health Care Systems, 881 S.W.2d 439, 444-45 (Tex.App.—El Paso 1994, writ denied).
Summary judgment procedural rules require that certified or sworn copies of all records or papers referred to in a supporting or opposing affidavit “shall be attached thereto or served therewith.” Tex.R.Civ.P. 166a(f); State v. Easley, 404 S.W.2d 296, 297 (Tex.1966). Failure to attach copies of the documents relied upon in forming Judge’s opinion was a fatal defect in the substance of the affidavit, and the trial court properly excluded it from consideration, Ceballos v. El Paso Health Care Systems, 881 S.W.2d at 444-45, because none of the documents was entitled to consideration in the summary judgment hearing. State v. Easley, 404 5.W.2d at 297. Without a consideration of the absent documents, there is no way to tell which portion of the documents Judge relied upon in expressing the substance of his opinions. Ceballos v. El Paso Health Care Systems, 881 S.W.2d at 445.6
Fitzgerald’s affidavit, given upon his oath to a notary public, began with this language:
My name is MARK B. FITZGERALD and I am over the age of eighteen and am competent to make this affidavit. I have personal knowledge of the matter contained herein.
Fitzgerald averred that the Potter suit was an “adversary proceeding,” as well as “a hard fought battle,” and an “arms length” transaction, and “[t]here was absolutely no collusion between” the Rodriquezes and the Ortegas. Further, the company employed to effectuate service of citation on the Rodriquezes was “well respected,” and he had not heard of “any complaints from other attorneys or the judiciary concerning” the company. Below the recitation of the events of service of citation upon the Rodriquezes in the Potter suit, the jurat read:
SUBSCRIBED AND SWORN TO BEFORE ME, by the said MARK B. FITZGERALD to which witness my hand an (sic) seal of office this 3rd day of August, 1994.
Immediately noticeable is that although Fitzgerald averred to his personal knowledge, he did not aver to the truth of the facts stated in the affidavit.
Farmers objected to the trial court that Fitzgerald’s affidavit contained facts and matters which would be inadmissible in evidence upon a trial of the matter since it contained averments which were “global and conclusory.” Farmers also objected to the form of the affidavit because it failed to set forth that Fitzgerald was competent to testify to the matters stated therein.
Farmers’s appellate contention against Fitzgerald’s affidavit is that it is substantively defective because the affiant did not aver that the statements made were true. If any of Farmers’s appellate complaints as to the substance of the affidavits are meritorious, we will overrule the contention of error. Bell v. Moores, 832 S.W.2d at 756.
[507]*507Except as authorized by statute,7 an affidavit is insufficient unless the allegations are direct and unequivocal and perjury can be assigned upon it. Brownlee v. Brownlee, 665 S.W.2d 111, 112 (Tex.1984); Morgan v. Amarillo Nat. Bank, 699 S.W.2d 930, 936 (Tex.App.—Amarillo 1985, writ ref'd n.r.e.). An affidavit which does not positively and unqualifiedly represent that the facts disclosed in the affidavit are true and within the affiant’s personal knowledge is legally insufficient, and cannot serve as summary judgment evidence. Humphreys v. Caldwell, 888 S.W.2d at 470-71. Since Fitzgerald’s affidavit did not contain an averment of the truth of the facts stated, the trial court did not err in excluding it from consideration. Id. The second point of error is overruled.
Not considering the Judge and Fitzgerald affidavits, the trial court determined that Farmers had no duty to defend the suit, and no duty to pay the resulting default judgment, and the Rodriquezes had no coverage under the policy for default judgment rendered in the Potter suit. By a collective argument presented under their final three points of error, the Rodriquezes and the Ortegas contend the trial court erred in these determinations. These contentions will be considered under the previously articulated standard for review of a summary judgment.
The court’s determinations that Farmers had no duty to defend the Rodriquezes prior to the default judgment in the Potter suit, or to indemnify the Rodriquezes or pay on their behalf any sums they were obligated to pay the Ortegas, and that the Rodriquezes had no coverage under the policy, are respectively challenged with the consolidated third, fourth and fifth points of error. The determinations must, under summary judgment principles, have been premised upon the no duty grounds presented by Farmers, viz.: First, that the Rodriquezes were never properly served with citation in the underlying suit and, therefore, Farmers never assumed a duty to defend prior to the entry of the default judgment; and second, that the Rod-riquezes failed and refused to cooperate with Farmers in contravention of the terms of the policy by (a) entering into the assignment of rights and covenant not to execute, (b) refusing to file a motion for new trial and refusing to cooperate with the attorney retained by Farmers in his attempt to file such a motion, and (c) acting in collusion with the Ortegas and their attorneys in executing affidavits used to strike the motion for new trial filed by the attorney retained by Farmers for the Rodriquezes. If any one of the grounds is meritorious, the summary judgment will be upheld. Borg-Warner Acceptance Corp. v. C.I.T. Corp. 679 S.W.2d 140, 142 (Tex.App.—Amarillo 1984, writ ref'd n.r.e.).
Without dispute, the policy required that the Rodriquezes notify Farmers of any lawsuit filed against them before Farmers’s duty to defend was invoked. In this regard, the Rodriquezes and the Ortegas conceded upon oral submission that Farmers’s duty was “triggered” by proper notice, i.e., that the insured was served and the insured forwarded the citation to the insurer. See Members Mutual Insurance Company v. Cutaia, 476 S.W.2d 278, 279 (Tex.1972); Members Ins. Co. v. Branscum, 803 S.W.2d 462, 466-67 (Tex.App.—Dallas 1991, no writ).
One of the purposes of requiring this notice is to inform the insurer that the insured has been served with process and that the insurer is expected to defend the suit. Harwell v. State Farm Mut. Auto. Ins. Co., 896 S.W.2d 170, 173 (Tex.1995). Consistent with that purpose, Farmers posited that it had no duty to file an answer until the plaintiff strictly complied with the rules of civil procedure concerning proper service of citation. See, e.g., Wilson v. Dunn, 800 S.W.2d 833, 836 (Tex.1990) (actual notice to defendant, without proper service of citation, was not sufficient to convey jurisdiction to support a default judgment).
[508]*508Service of citation in the Potter suit was governed by the specification in Rule 106, Texas Rules of Civil Procedure, that “[u]n-less the citation or an order of the court otherwise directs, the citation shall be served by any person authorized by Rule 103.... ” Rule 103 authorizes (1) any sheriff or constable or other person authorized by law, or (2) any person authorized by law or by written order of the court who is not less than eighteen years of age to serve citation.
Farmers documented in the trial court that the returns of the citations were executed by Dennis Snyder, an employee of U S Legal Support in Amarillo. Snyder was neither a sheriff nor constable, and he served the citations as a person purportedly authorized by a written order of the trial court. However, the order was one entered on 8 May 1990 by the district judges of Potter County, authorizing “JEFF HOUCHIN, d/b/a U S LEGAL SUPPORT, and the U S LEGAL SUPPORT Offices in Austin, Dallas, Ft Worth, Houston, Lubbock, and San Antonio, or any duly authorized employee or agent thereof’ to serve citations.
Farmers also documented that Snyder, employed by the U S Legal Support Office in Amarillo, was not a duly authorized employee or agent of any of the offices in the cities named in the order, and that the order does not authorize Snyder, or any other employee of the Amarillo division of U S Legal Support, to execute service of citation. Pointing out that there are no presumptions in favor of valid issuance, service, and return of citation, and it cannot be presumed otherwise, Wilson v. Dunn, 800 S.W.2d at 836; Uvalde Country Club v. Martin Linen Supply Co., 690 S.W.2d 884, 885 (Tex.1985), Farmers represents that the blanket order will not support valid service of citation upon the Rodri-quezes.
Other than reliance upon Fitzgerald’s affidavit, which was properly excluded from consideration, and Mosley’s deposition testimony that a prudent attorney would have answered the lawsuit despite any defects on the face of the citation, the Rodriquezes and the Ortegas offered nothing to controvert Farmers’s pri-ma facie showing of defective service. Indeed, Mosley, presented by the Rodriquezes and the Ortegas as an expert regarding issuance of service of citation, conceded in his deposition that service of citation by Snyder would only be proper upon a written order of the trial court authorizing his service because he was not a constable, sheriff or deputy at the time the citations were served.
Still, the Rodriquezes and the Ortegas argue that to accept Farmers’s reasoning would relay to insurers that they would have “no duty to defend your insured if he/she is served in a fashion that is not in 100% strict compliance with rules of service ... and may allow a default judgment against its insured.” They conclude such would be “a preposterous, anti-consumer ruling” and would conflict with Mr. Mosley’s testimony that he would have protected his client by filing an answer even if he knew the service was defective.
Nevertheless, the want of certainty in a citation cannot be supplied by construction or intendment. Smith v. Buckholts State Bank, 193 S.W. 730, 731 (Tex.Civ.App.—Austin 1917, no writ). The manner of service must, in fact, strictly comply with the rules of civil procedure. And when the manner of service conflicts with the terms of the citation, it violates rule 106 and is invalid. Smith v. Commercial Equipment Leasing Co., 678 S.W.2d 917, 918 (Tex.1984). To hold otherwise in this instance would be to gratuitously subject Farmers to liability before it received notice that the Rodriquezes were sued and were properly served or that they had accepted service and appeared in the suit. Harwell v. State Farm Mut. Auto. Ins. Co., 896 S.W.2d at 174.
Given the invalidity of the service of citation upon the Rodriquezes, the trial court was without jurisdiction to render the default judgment against them. Wilson v. Dunn, 800 S.W.2d at 836. As a result, the default judgment was subject to being set aside upon a motion for new trial and, if the court failed to do so, the judgment was subject to reversal upon appeal because of the defective service even though the issue was not raised in the motion for new trial. Id. at 837.
The insurance policy provided that no action shall lie against Farmers unless, as a [509]*509condition precedent thereto, there shall be full compliance with the terms of the policy. One of those terms obligated the Rodri-quezes, upon being served in the Ortegas’ suit, to immediately forward the suit papers to Farmers, and to “cooperate with [Farmers] and, upon [Farmers’s] request, assist in making settlement, in the conduct of suits ... and ... shall attend hearings and trials and assist in securing and giving evidence and obtaining the attendance of witnesses.”
Whether the Rodriquezes forwarded the Potter suit papers to Fanners was not established. However, it is undisputed that when Farmers learned of the default judgment, Farmers retained attorney Mosley and then attorney Brooks to file a motion for new trial on behalf of the Rodriquezes. Mosley considered the filing of a motion for new trial to be foreclosed by the Rodriquez-Ortega covenant not to execute and assignment agreement, but Brooks filed a motion for new trial and an appeal bond on behalf of the Rodri-quezes. When he did so, the Rodriquezes, believing the motion for new trial would be a violation of their agreement with the Orte-gas, furnished to the Ortegas’ attorney their affidavits stating that Brooks was not authorized to file the motion on their behalf. On the strength of the affidavits, the Ortegas’ attorney challenged Brooks’s authority to act on behalf of the Rodriquezes. These actions caused the filings by Brooks to be stricken and the ensuing appeal to be forestalled.
Because of the provisions in the insurance policy granting Farmers the right to defend suits and requiring the Rodriquezes to cooperate with Farmers, the Rodriquezes could not make any agreement which would operate to impose liability upon Farmers or would deprive Farmers of the use of a valid defense. McGuire v. Commercial Union Insurance Co. of N.Y., 4B1 S.W.2d 347, 852 (Tex.1968). It is undisputed that because of their agreement with the Ortegas, the Rodri-quezes failed to cooperate with Farmers in its efforts to set aside the default judgment. Their failure to cooperate, in violation of their obligation under the insurance policy, resulted in prejudice to Farmers in the amount of 1.65 million dollars, which was more than 16 times the coverage under Farmers’s policy. See Liberty Mut. Ins. Co. v. Cruz, 883 S.W.2d 164, 166 (Tex.1993). Thus, Farmers was prejudiced as a matter of law, and as a consequence, Farmers is not liable for the default judgment against the Rodriquezes. Harwell v. State Farm Mut. Auto. Ins. Co., 896 S.W.2d at 175.
Notwithstanding, the Rodriquezes and the Ortegas contend the trial court’s determination there was no coverage under the policy for the Potter suit was erroneous. This is so, they submit, because the determination was based upon Farmers’s allegations that the Rodriquezes failed to cooperate as required by the policy although Farmers had first breached the policy terms in failing to settle the claim prior to judgment. Once Farmers breached its duty to settle, they argue, they were excused from any obligation to cooperate.
Absent from the Rodriquezes’ and the Ortegas’ response to Farmers’s motion for summary judgment was any evidence to support the bare allegation of Farmers’s failure to settle the claim. They presented nothing to controvert Honea’s deposition testimony, and Lydia Rodriquez’s own deposition testimony and letter to Honea, that she adamantly opposed any settlement upon her belief that David Ortega was not bitten or injured. Nor did they present controverting evidence to Farmers’s showing that the default judgment in all likelihood would have been set aside upon a motion for new trial, but that the Rodriquezes refused to allow the motion to be filed even after a written demand by Farmers and assurances that the failure to allow the filing could affect their coverage under the policy. The only offer of contravention to Farmers’s allegation of collusion between the Rodriquezes and Ortegas were Judge’s and Fitzgerald’s affidavits which were properly excluded from consideration.
Moreover, once Farmers moved for summary judgment on the ground, and evidenced as a matter of law, that the Rodri-quezes failed to cooperate with it and were in collusion with the Ortegas, the Rodriquezes and the Ortegas assumed the burden to negate the pleaded exception from insurance coverage. Brooks v. Blue Ridge Ins. Co., 677 S.W.2d 646, 651 (Tex.App.—Amarillo 1984, [510]*510writ ref'd n.r.e.). Then, to avoid Farmers’s entitlement to summary judgment on that ground, the Rodriquezes and the Ortegas were required to expressly present to the trial court any reason and summary judgment proof to establish a fact issue. City of Houston v. Clear Creek Basin Authority, 589 S.W.2d at 678. However, they offered no evidence that could be considered, thereby failing to raise a fact issue concerning Farmers’s first breach which would excuse the Rodriquezes’ failure to cooperate.
Still, the Rodriquezes and the Orte-gas next contend that Farmers waived its defense of non-coverage since it assumed the Rodriquezes’ defense without adequately reserving its rights to obtain a non-waiver agreement. The failure of Farmers to reserve its rights, the Rodriquezes and the Ortegas argue, estops it from asserting non-coverage.
Estoppel requires a showing that the insured was prejudiced by the conduct of the insurer. State Farm Lloyds, Inc. v. Williams, 791 S.W.2d 542, 552 (Tex.App.—Dallas 1990, writ denied). To satisfy this requirement, the Rodriquezes and the Orte-gas rely upon (1) an error in the reservation of rights letter, and (2) Mosley’s negligence in the preparation of the agreement between the Rodriquezes and the Ortegas, and his advice to the Rodriquezes not to file a motion for new trial.
Aside from the fact that the letter was not presented by the Rodriquezes and Ortegas as summary judgment proof, they conceded on appeal that the letter was a “thoroughly written reservation of rights letter [which] would seem to cover all angles.” Their only complaint is that the letter is “from the wrong insurance company,” because the author of the letter stated it was written on behalf of “Fire Insurance Exchange.”8 This error is viewed by the Rodriquezes and the Ortegas as estopping Farmers from relying upon the letter as a reservation of its rights.
However, the Rodriquezes and Ortegas have failed to show either reliance or prejudice by the mistake in the letter. This obtains, because their cognizance of the relationship of Farmers and Fire Insurance Exchange is evinced by this statement in their agreement: “ ‘Farmers Insurance’ means Fire Insurance Exchange, Texas Farmers Insurance Company, any of the Farmers Insurance Group of Companies, their agents, employees and attorneys.” Further, Mosley stated that he had seen the letter and conferred with J.E. Sauseda, the Rodriquezes’ private counsel, concerning the letter, and that there was “never any question raised by either Mr. Sauseda or the Rodriguezes (sic) concerning this reservation of rights letter.”
The Rodriquezes and the Ortegas have not supported their argument of negligence by Mosley, hired by Farmers to defend the Rod-riquezes, in drafting the Rodriquez-Ortega covenant not to execute/assignment agreement, and in advising the Rodriquezes not to file a motion for new trial. They have not contradicted the record revelations that the offer of a covenant not to execute was made by Fitzgerald, not Mosley, and was communicated to Sauseda before Mosley was retained to represent the Rodriquezes. When Mosley presented the agreement to the Rodriquezes, they told Mosley they were going “to rely on what J.E. said,” and they consulted with Sauseda in executing the agreement.
More important, however, is that the Rod-riquezes have not pointed to any evidence evincing that they were prejudiced by Mosley’s drafting the agreement or by his advising them not to file a motion for new trial. Rather, the evidence is that by execution of the agreement, the Rodriquezes themselves have been freed from liability on the default judgment. Then, if any prejudice flowed from Mosley’s actions, the prejudice is only to the Ortegas, but that is immaterial to Farmers’s obligation under its policy, which was “[t]o pay on behalf of the [Rodriquezes] all sums which the [Rodriquezes] shall become legally obligated to pay as damages.” In this light, it becomes unnecessary to further address the question whether the Rodriquez-Ortega agreement constitutes a failure on the part of the Rodriquezes to cooperate with Farmers.
[511]*511Finally, the Rodriquezes and the Ortegas contend the summary judgment is an improper collateral attack on the default judgment, because the summary judgment questions the service of citation in the Potter suit. They submit that since the default judgment is final, its recitations of proper service must be taken as true and may not be impeached by extrinsic evidence. See Jordan v. Texas Pac. Coal & Oil Co., 152 S.W.2d 875, 879 (Tex.Civ.App.—Amarillo 1941, writ ref'd) (where judgments are collaterally assailed, their jurisdictional recitals are not open to attack but import absolute verity).
Farmers, which was not a party to the Potter suit, replies that it is not attempting by the underlying suit to void the default judgment in the Potter suit; instead, it seeks the determinations whether it was obligated to defend the Rodriquezes in the Potter suit prior to the default judgment, and whether it is obligated to pay any part of the judgment. The judgment in the Potter suit fixed the Rodriquezes’ monetary liability to the Orte-gas. It did not involve, nor adjudicate, the question of the coverage of Farmers’s policy issued to the Rodriquezes. The questions of liability and coverage are separate and distinct, and the establishment of liability in the Potter suit did not bind Farmers on the question of coverage under its policy. It follows that the underlying suit was not a collateral attack on the judgment in the Potter suit, and that judgment does not preclude Farmers from litigating the question of coverage in the underlying suit. Employers Cas. Co. v. Block, 744 S.W.2d 940, 943 (Tex.1988). The third, fourth and fifth points of error are overruled.
Farmers advances a cross-point, conditioned upon a reversal and remand, concerning a fact issue of its entitlement to attorney’s fees. The overruling of the Rodri-quezes’ and the Ortegas’ contentions of error pretermits a discussion of the conditional cross-point. Tex.R.App.P. 90(a).
The summary judgment is affirmed.
