OPINION
PER CURIAM.
This original petition for a writ of mandamus challenges a district court order that dismissed a complaint for forum non conveniens.

SUMMARY
In a series of prior decisions, this court has stated that mandamus is the proper method for challenging the dismissal of a case on forum non conveniens grounds. Those decisions, however, did not address the interplay between writ relief and the availability and adequacy of an appeal. But in other decisions, *841 this court has recognized that an appeal is generally an adequate legal remedy that precludes writ relief.[1] Consequently, we take this opportunity to clarify that if all prerequisites for finality are met, an order that dismisses a case for forum non conveniens is a final judgment that should be reviewed on appeal, not through a writ petition.
Although this writ petition could be denied solely on procedural grounds because petitioners had an adequate remedy in the form of an appeal from the district court's order, petitioners' time to appeal has run. Given that our prior case law may have misled petitioners to forgo their appeal, we will consider this petition. Ultimately, we deny the petition because petitioners have failed to meet their burden of demonstrating that extraordinary relief is warranted.

FACTS
Unfortunately, the petition, answer, and accompanying documents do not provide a clear picture of the facts in this case. The underlying district court case involved a dispute arising out of the real parties in interest's sale of the Shiatsu Center of Las Vegas, Ltd., a massage business, to Julie Tzoo Jy Pan and the petitioners, Peter Ta-Hsien Pan, Vivien Yang, and Hsiao Hung Sun.
The petitioners sued the real parties in interest for, among other things, breach of contract, fraud, misrepresentation, and negligence. The real parties in interest then moved to dismiss the action on forum non conveniens grounds. The district court dismissed the case in a written order filed March 6, 2003. The real parties in interest then served notice of the dismissal order's entry on March 17, 2003, thus starting the clock on petitioners' time to appeal. Subsequently, petitioners filed this petition for a writ of mandamus, requesting this court to direct the district court to vacate its dismissal order and entertain their action. The real parties in interest filed an answer at this court's request.

DISCUSSION
Under NRS 34.170, a writ of mandamus is proper only when there is no plain, adequate and speedy legal remedy.[2] This court has previously pointed out, on several occasions, that the right to appeal is generally an adequate legal remedy that precludes writ relief.[3] Additionally, writ relief is not available to correct an untimely notice of appeal.[4] And we have determined that even if an appeal is not immediately available because the challenged order is interlocutory in nature, the fact that the order may ultimately be challenged on appeal from the final judgment generally precludes writ relief.[5] Because this petition challenges a district court order that dismissed petitioners' complaint, which is a final, appealable judgment under NRAP 3A(b)(1),[6] writ relief is inappropriate.
*842 Nevertheless, on several occasions this court has reviewed forum non conveniens dismissals by petitions for a writ of mandamus. The first such case is Swisco, Inc. v. District Court,[7] in which petitioner Swisco filed a petition for a writ of mandamus that challenged a district court order that dismissed its action for forum non conveniens. This court relied on a quote from an early twentieth century Nevada case, Floyd v. District Court,[8] to conclude that mandamus was the proper method of review. Specifically, the Swisco court stated: "`where a district court erroneously decides that it has no jurisdiction, the writ of mandamus is the proper remedy to compel that tribunal to do that which the law prescribes it should doassume jurisdiction and proceed with the cause.'"[9] The Swisco court then discussed whether forum non conveniens mandated dismissal, and concluded that the district court should not have dismissed Swisco's complaint because the moving party's affidavit did not include enough facts to justify depriving the plaintiff of its chosen forum. Consequently, the Swisco court issued a writ of mandamus directing the district court to assume jurisdiction of the case, and purported to "remand" the case for further proceedings.[10]
Some years later, in Buckholt v. District Court,[11] this court again issued a writ of mandamus directing a district court to accept jurisdiction of an action after the district court dismissed the complaint for forum non conveniens. The opinion did not discuss the propriety of writ relief; instead it simply quoted Swisco for the proposition that "`where the district court wrongfully or erroneously divests itself of jurisdiction, . . . mandamus is the proper remedy.'"[12] This court concluded that the district court should not have dismissed the plaintiffs' complaint because the plaintiffs chose to litigate the case in Nevada, and the defendant was a resident corporation of Nevada that conducted business in the state.[13]
Later, in Eaton v. District Court,[14] a 1980 decision, this court granted a petition for a writ of mandamus that challenged a district court order dismissing the petitioner's complaint after determining that Montana was a more convenient forum. Again, this court did not discuss the appropriateness of writ relief or the order's appealability. Instead, the Eaton opinion merely focused on the merits of the forum non conveniens claim and concluded that the forum non conveniens doctrine involved a balancing of several factors.[15] This opinion also "remanded" the case for further proceedings.
One year after Eaton, this court decided Payne v. District Court,[16] another writ petition that challenged an action's dismissal on forum non conveniens grounds. In Payne, this court recognized that the forum non conveniens doctrine's application is within the district court's discretion and determined that because the underlying dismissal motion was supported by the factors articulated in Eaton, mandamus was not available to review the district court's discretion.[17] Consequently, this court denied the petition.
After issuing the Eaton and Payne opinions, this court issued an opinion in Martin v. DeMauro Construction Corp.,[18] which was an appeal from an order dismissing an action on forum non conveniens grounds. This court determined that the district court erred in dismissing the action because Nevada was a *843 proper forum.[19] Although it cited its prior decision in Eaton, this court did not address the propriety of addressing the issue in the context of a writ petition.

Floyd v. District Court
Swisco and the related subsequent cases borrowed a quote from Floyd to justify writ review of forum non conveniens dismissal orders without analyzing the propriety of writ relief. An examination of Floyd reveals that it does not support review by writ petition in cases dismissed for forum non conveniens.
Floyd involved a petition for a writ of mandamus challenging a district court order that dismissed an appeal from justice's court.[20] Apparently, the Union Township Justice's Court in Humboldt County entered judgment against petitioners (and defendants below) Elizabeth Floyd and James Guthrie for $405.75.[21] Floyd appealed to the district court and deposited the judgment amount, in lieu of an appeal bond, with the justice of the peace. The plaintiffs from the justice's court case moved to dismiss the appeal as untimely, and for failure to pay the costs on appeal. The district court dismissed the appeal in a written order.[22] Floyd then filed a petition for a writ of mandamus in this court.
The Nevada Constitution vests the district courts with final appellate jurisdiction in all cases arising in the justices' courts.[23] Prior to Floyd, this court adopted the rule that a district court's dismissal of an appeal from justice's court, even though erroneous, is final and not subject to appellate review.[24] In Floyd, we framed the primary issue as: "`Will mandamus lie to review the action of the district court and to compel the district court to proceed in a case in which that court has divested itself of jurisdiction by erroneously dismissing an appeal?'"[25]
Ultimately, we concluded that if a district court takes jurisdiction of an appeal and acts, its acts are not subject to review through a petition for a writ of mandamus, but if the district court wrongly decides that it lacks jurisdiction, a writ of mandamus is the proper way to compel the court to do what the law requiresassume jurisdiction and proceed with the appeal.[26] In essence, Floyd decided that even though the district courts have final appellate jurisdiction in cases arising in the justices' courts, when the district court erroneously divests itself of appellate jurisdiction, the dismissal is reviewable by this court through a petition for a writ of mandamus.
Notably, Floyd did not acknowledge that a writ of mandamus is only available if there is no plain, speedy, and adequate remedy available.[27] Floyd's lack of an adequate remedy was, however, implicit in our decision. The district court's final appellate jurisdiction in cases arising in justice's court precluded Floyd from appealing the district court's dismissal order to this court. Thus, a writ petition was the only available means to challenge the district court's decision.
Unlike the situation in Floyd, in Swisco and subsequent cases, the petitioners had the right to appeal from the district court's dismissal for forum non conveniens because the dismissal orders were appealable final judgments.[28] Yet, the Swisco court failed to address the availability of an appeal. Instead, it adopted the quote from Floyd without recognizing that Floyd's holding does not apply when an appeal is available. Accordingly, Floyd does not justify straying from this court's long-standing rule that the right *844 to appeal is generally an adequate legal remedy that precludes writ relief.
As a result, Swisco, Buckholt, Eaton, and Payne are overruled to the extent that they conclude that a writ petition is the appropriate vehicle for challenging a final judgment entered on forum non conveniens grounds.
Nevertheless, because we previously indicated that the proper method of review in this type of case is a petition for a writ of mandamus, we will exercise our original jurisdiction and consider this petition.

Petitioners' NRAP 21(a) burden
NRAP 21(a) requires a petition for extraordinary relief to contain:
a statement of the facts necessary to an understanding of the issues presented by the application; a statement of the issues presented and of the relief sought; a statement of the reasons why the writ should issue; and copies of any order or opinion or parts of the record which may be essential to an understanding of the matters set forth in the petition.
Petitioners carry the burden of demonstrating that extraordinary relief is warranted.[29]
The reasons for NRAP 21(a)'s requirements are simple. A petition for writ relief invokes this court's original jurisdiction. Our review in a writ proceeding is limited to the argument and documents provided by the parties. If essential information is left out of the petition and accompanying documentation, we have no way of properly evaluating the petition.[30] We routinely receive and deny writ petitions that fail to comply with NRAP 21(a). The time and energy expended reviewing these deficient petitions wastes this court's valuable and limited judicial resources.
Here, petitioners failed to provide a comprehensive factual analysis in the petition, and they neglected to submit necessary parts of the record. Although this petition challenges a district court order that dismissed petitioners' complaint based upon forum non conveniens, the resolution of this petition depends on the validity and enforceability of a forum selection clause in the March 15, 2002 stock purchase agreement signed by real party in interest Ming Tang Lin and Julie Tzoo Jy Pan. Petitioners, however, declined to explain their relationship with Julie Pan, who was a party to the disputed transaction, but is not a plaintiff in the underlying district court case, and is not a petitioner in this writ petition. In addition, petitioners failed to provide documents that they executed in escrow during the sale of the Shiatsu Center. The escrow documents and an understanding of Julie Pan's relationship with petitioners appear necessary to determine if the forum selection clause in the stock purchase agreement can be enforced against petitioners. Petitioners failed to carry their NRAP 21(a) burden, and consequently, they have not demonstrated that extraordinary relief is warranted. Accordingly, we deny their petition for a writ of mandamus.
