OPINION
Appellant Ronald R. Wagner sued ap-pellees Roberto D’Lorm and Edward P. Dancause 1 in Travis County district court seeking a declaration that a default judgment previously obtained by D’Lorm and his attorney, Dancause, against Wagner in a Zapata County district court was void. D’Lorm filed a plea to the jurisdiction asserting that the trial court did not have subject-matter jurisdiction to declare void the judgment of another district court. Wagner moved for summary judgment on his declaratory-judgment claim. The trial court granted D’Lorm’s plea to the jurisdiction and denied summary judgment for Wagner, finding summary judgment “improper” for jurisdictional reasons. In a single issue on appeal, Wagner asserts that the trial court erred in granting D’Lorm’s plea to the jurisdiction and in denying his motion for summary judgment because the Zapata County default judgment is void and, therefore, may be collaterally attacked in another court of equal jurisdiction. We will reverse the trial court’s order and remand the cause for further proceedings.
FACTUAL AND PROCEDURAL BACKGROUND
In 2003, D’Lorm filed suit against Ronald R. Wagner & Co., L.P., a Texas limited partnership (“the partnership”), in Zapata County seeking damages for injuries he allegedly received in an accident with a vehicle that was owned and operated by the partnership. The record indicates that D’Lorm made several unsuccessful attempts to serve the partnership by serving Wagner, who was a limited partner in the partnership and its agent for service. The record does not reflect that Wagner was ever served, either personally or as agent for the partnership. The record also shows that Wagner was never added as an individual defendant in the Zapata County lawsuit, nor did he appear in any capacity before the Zapata County district court. Even though Wagner was not a party to the suit and evidently had not been served, the Zapata County court rendered a default judgment against him personally. The record shows that the style on the default judgment was different from previous documents filed in the case. Whereas previous pleadings were styled “Roberto D’Lorm v. Ronald R. Wagner & Co., L.P.,” the judgment was styled “Roberto D’Lorm v. Ronald R. Wagner.” The judgment recited that “Defendant, although duly cited to appear and answer herein, has failed to file an answer within the time allowed by law” and awarded D’Lorm damages against Wagner.
In January 2007, about three years and five months after the default judgment was rendered, Wagner filed suit against D’Lorm and his attorney, Dancause, in Travis County district court seeking a declaration that the Zapata County default judgment was void. Wagner also sought damages for slander of title and injury to his credit reputation, but he ultimately nonsuited those claims. D’Lorm answered and filed a plea to the jurisdiction asserting that “one district court cannot overturn the judgments and decrees of another,” and that the trial court therefore lacked jurisdiction to consider Wagner’s request for declaratory relief. Before the trial court ruled on D’Lorm’s plea to the jurisdiction, Wagner filed a motion for summary judgment on his claim for declar *191 atory relief, arguing that the Zapata County default judgment was void. After hearing arguments, the trial court granted D’Lorm’s plea to the jurisdiction and denied Wagner’s motion for summary judgment on the ground that it was “improper,” citing issues relating to the court’s jurisdiction. Wagner perfected this appeal.
STANDARD OF REVIEW
Whether a court has subject-matter jurisdiction is a question of law, which we review de novo.
Texas Dep’t of Parks & Wildlife v. Miranda,
In a challenge solely to the pleadings, we decide if the plaintiff has alleged sufficient jurisdictional facts to show the trial court’s subject-matter jurisdiction, using a liberal construction in favor of the plaintiff.
Miranda,
DISCUSSION
In his sole point of error, Wagner asserts that the trial court erred when it granted D’Lorm’s plea to the jurisdiction and denied his motion for summary judgment. Wagner contends that he mounted a valid collateral attack on the Zapata County judgment by alleging facts showing that the judgment is void because the Zapata County court lacked jurisdiction over him as he was neither served nor was a party to the suit. Wagner asserts that “because the [Zapata County] judgment is void ... it can be collaterally attacked in any court of equal jurisdiction.” D’Lorm counters that Wagner has failed to properly employ the options available to him to challenge the Zapata County judgment. Citing
McEwen v. Harrison,
In this appeal from the grant of D’Lorm’s plea to the jurisdiction on the pleadings, our task is to decide whether Wagner has pleaded sufficient jurisdictional facts to invoke the trial court’s subject-matter jurisdiction, using a liberal construction of his pleadings.
Miranda,
D’Lorm was involved in an accident ... with a vehicle owned and operated by RONALD R. WAGNER & CO. L.P, a *192 Texas Limited Partnership.... [Defendants] filed [D’Lorm’s petition] in the 49th Judicial District of Zapata County, Texas, in Cause No. 5,368 styled ROBERTO D’LORM, PLAINTIFF V. RONALD R. WAGNER & CO., LP, a Texas Limited Partnership. Plaintiff RONALD R. WAGNER was not named a Defendant, nor was he ever served with process.... On August 29th, 2003, [the defendants] took a Default Judgment against [Wagner personally] ... notwithstanding the fact that [Wagner] was neither a named Defendant or ever served with process.... The trial court had no jurisdiction over [Wagner].... Inasmuch as [Wagner] was not a Defendant in Cause No. 5,368, nor was he served with process, the 49th Judicial District Court of Zapata County, Texas had no jurisdiction over [Wagner] and the Default Judgment against him should be declared void and of no further force and effect.
A judgment is void, and thus may be collaterally attacked, if the rendering court had “no jurisdiction over a party or his property, no jurisdiction of the subject matter, no jurisdiction to enter the particular judgment, or no capacity to act as a court.”
Austin Indep. Sch. Dist. v. Stem Club,
Here, Wagner pleaded that he was neither named as a party nor served with process. If true, that would mean that the Zapata County district court committed fundamental error by rendering judgment against Wagner because he was not a party,
see id.,
and that the court lacked personal jurisdiction over Wagner when it rendered default judgment against him because he was not served,
Kawasaki Steel Corp.,
We need not decide at this juncture whether the Zapata County default judgment is actually void. Having decided that Wagner’s pleaded facts, if true, would render the Zapata County default judgment void, we need only determine whether the Travis County district court had jurisdiction to entertain his suit.
The supreme court addressed this issue by implication in
Browning v. Placke,
a mandamus action in which the relator sought relief from an order rendered by a Lee County district court that declared void a judgment rendered three years earlier by a Dallas County district court.
We draw two conclusions from Browning. The first is that if a challenged judgment is void, a different, co-equal court can properly render judgment declaring it void. This conclusion follows logically from the holding of the case and, more specifically, from the opening paragraph of the court’s opinion:
This original mandamus proceeding presents the question whether a district court may declare void the judgment of another district court. We hold that absent a showing that the prior court lacked jurisdiction, no such declaration is permissible.
Id. at 362 (emphasis added). The second conclusion — the one that answers the question presented here — -follows as a matter of course: if the trial court may properly render such a judgment, it necessarily must have jurisdiction to render it.
Other cases addressing the issue directly or in dicta also hold or imply that courts have jurisdiction to declare void the judgment of another court.
See, e.g., Segrest v. Segrest,
McEwen v. Harrison Is Not Applicable
D’Lorm argues that Wagner has “waived any rights to attack the [default] judgment” in the present case because he failed to employ one of the remedies enumerated in
McEwen v. Harrison,
when the time for filing a motion for new trial has expired and relief may not be obtained by appeal, a proceeding in the nature of a bill of review is the exclusive method of vacating a default judgment rendered in a case in which the court had jurisdictional power to render it.
Id,,
at 709 (construing Texas Rule of Civil Procedure 329b to limit remedies used to directly attack judgment). The phrase

“jurisdictional power” means “ ‘jurisdiction over the subject matter, the power to hear and determine cases of the general class to which the particular one belongs.’ ”
Middleton v. Murff,

a proceeding instituted for the purpose of correcting the earlier judgment. It may be brought in the court rendering the judgment or in another court that is authorized to review the judgment on appeal or by writ of error [i.e., restricted appeal]. The purpose of a direct attack is to change the former judgment and secure the entry of a correct judgment in lieu of the earlier incorrect one.
Austin Indep. Sch. Dist.,
“Judgment-Interpretation Cases” Are Not Applicable
The present case is also distinguishable from the line of cases holding that a court has no jurisdiction to render declaratory
*195
judgment to “interpret” a prior judgment. In the present case, Wagner does not seek to “interpret” the Zapata County judgment, i.e., he does not ask the court to construe the judgment’s substantive provisions.
See, e.g., Martin v. Dosohs I Ltd.,
In light of the foregoing, we hold that Wagner’s pleadings were sufficient to give the trial court subject-matter jurisdiction to adjudicate his claims for declaratory relief. The court therefore erred when it granted D’Lorm’s plea to the jurisdiction. We sustain that portion of Wagner’s issue on appeal.
Denial of Wagner’s Motion for Summary Judgment
In the second portion of his issue on appeal, Wagner asserts that the trial court erred in denying his motion for summary judgment on his claims for declaratory relief. The trial court denied Wagner’s motion in light of its decision that it lacked jurisdiction to adjudicate his declaratory-judgment claim. The denial of a motion for summary judgment is generally not reviewable on appeal.
See Texas Mun. Power Agency v. Public Util. Comm’n,
CONCLUSION
We hold that the trial court'had subject-matter jurisdiction to hear and consider Wagner’s declaratory-judgment suit. We therefore reverse the district court’s dismissal order and remand the cause to that court for further proceedings.
Notes
. Dancause did not file a brief in this appeal.
. Determining the type of attack mounted by Wagner here is important both for the analysis in this appeal and because it determines the presumptions that the trial court will give to the Zapata County judgment on remand.
This Court has held that, in a collateral attack, the challenger must show error on the face of the judgment itself,
