MEMORANDUM *
Debtor-Appellants Christopher D. Nic-holls and Kristine J. Nicholls (the “Nic-holls”) appeal a decision of the district court accepting jurisdiction over Creditor-Appellees John F. Buchan and Gloria Bu-chan’s (the “Buchans”) appeal of the decision of the bankruptcy court. We vacate for lack of jurisdiction and remand to the bankruptcy court for further proceedings.
I
The bankruptcy court issued a judgment on April 26, 2000, awarding $574,167 plus $3,000 to the Buchans on the merits of their claim, subtracting $16,000 to be paid by them in sanctions, and simultaneously awarding $138,921.51 in attorneys’ fees to the Nicholls. This judgment was modified by the court sua sponte on June 12, 2000, reducing the amount of attorneys’ fees awarded individually to the *732Nicholls to $55,000 and reserving the remainder of the fees to their estate. The Buchans appealed to the district court on June 22, 2000. The Nicholls argued that because no aspect of the modified judgment was appealed and because it did not disadvantage the Buchans, the district court was required to compute the jurisdictional filing deadline from the date of the entry of the original judgment. Because the Buchans’ appeal was 57 days removed from the original judgment, the Nicholls moved to dismiss the appeal for lack of jurisdiction. The district court denied the motion and subsequently issued an order, on January 25, 2001, ruling that attorneys’ fees were unavailable to the Nicholls on two of their claims litigated before the bankruptcy court. The Nicholls challenge the district court’s jurisdiction to hear the Buchans’ appeal. We must first determine our own appellate jurisdiction before we can proceed to the merits.1
“Although we ordinarily lack jurisdiction when the lower appellate decision remands for further factual findings related to a central issue raised on appeal, we may assert jurisdiction if the appellate ‘issue is legal in nature and its resolution either 1) could dispose of the case or proceeding and obviate the need for factfinding; or 2) would materially aid the bankruptcy court in reaching its disposition on remand.’ ” Dominguez v. Miller (In re Dominguez), 51 F.3d 1502, 1506-07 (9th Cir.1995) (quoting Bonner Mall P’ship v. U.S. Bancorp Mortgage Co. (In re Bonner Mall P’ship), 2 F.3d 899, 904 (9th Cir.1993)).
In the present case, the Nicholls challenge the appellate jurisdiction of the district court under 28 U.S.C. § 158(a)(1), because of the Buchans’ failure to comply with Rule 8002 of the Federal Rules of Bankruptcy Procedure. Rule 8002 requires that appeals of final decisions of the bankruptcy court be filed within 10 days of entry of the court’s judgment or within 10 days of the court’s resolution of a timely motion for reconsideration. There is no dispute as to when any of the filings at issue were made, and the district court agrees that “the Buchans’ appeal must be dismissed as untimely unless the ten day period began to run with the entry of the amended judgment on June 12, 2000.” Therefore, this is a purely legal issue that, if resolved in the appellants’ favor, would result in the dismissal of the Buchans’ appeal to the district court and thereby obviate the need for further factual determinations by the bankruptcy court. Accordingly, we have jurisdiction to hear the Nicholls’ appeal under 28 U.S.C. § 158(d).
II
We review the district court’s decision on appeal from a bankruptcy court de novo. Gruntz v. County of Los Angeles (In re Gruntz), 202 F.3d 1074, 1084 n. 9 (9th Cir.2000) (en banc).
“The provisions of Bankruptcy Rule 8002 are jurisdictional; the untimely filing of a notice of appeal deprives the appellate court of jurisdiction to review the bankruptcy court’s order.” Anderson v. Mouradick (In re Mouradick), 13 F.3d 326, 327 (9th Cir.1994). An untimely motion for reconsideration will not extend the time in which a notice of appeal may be filed. Preblich v. Battley (In re Preblich), 181 F.3d 1048, 1057 (9th Cir.1999). Here, the Buchans filed their motion for reconsideration of the bankruptcy court’s April *73326, 2000 decision, which was entered on April 27, 2002, on May 10, 2000, three days after the 10 day period for filing the motion had run.
The district court ruled that the appeal was timely under the theory that the June 12, 2000, sua sponte order modifying its judgment materially affected the rights of the parties, thereby tolling the time in which the Buchan’s could file their notice of appeal until 10 days from that date. This was error. In support of its ruling, the district court relied on County of Imperial v. United States, 348 F.2d 904 (9th Cir.1965), which holds that amendment of a summary judgment order to include a second parcel of land as covered by ruling on property tax liens did not correct a mere “clerical mistake” under Fed. R.Civ.P. 60(a) but constituted a substantial, material change to the judgment, thereby tolling the period in which the government was permitted to appeal, id. at 905. However, we have subsequently held that a modified judgment that benefits the appellant “ ‘cannot possibly subject the entire original judgment to a new opportunity’ for appeal.” Atchison, Topeka & Santa Fe v. Cal. State, 102 F.3d 425, 427 (9th Cir.1996) (quoting Harman v. Harper, 7 F.3d 1455, 1457 (9th Cir.1993)). The issue before us therefore turns upon how we interpret the bankruptcy court’s original judgment.
The court’s judgment stated, pre-modifi-cation, that “Defendants Christopher and Kristine Nicholls (“Defendants”) are awarded judgment against Plaintiffs [the Buchans] in the amount of $138,921.51 for attorneys’ fees and costs associated with the defense of the nondischargability claims, the avoidance of the Deed of Trust on the Sultan property, the commercial reasonableness of the collection of accounts receivable and the amount of Plaintiffs’ claim.” The court then stayed this judgment pending appeal. The Buchans argue that the bankruptcy court intended for this award to be paid to the estate, from which the Buchans are eligible to recover as creditors, and that the amended order harmed them materially by separating $55,000 to be paid to the Nicholls personally.
This interpretation of the court’s original order contradicts, not only the plain language of the order which awards fees and costs to the Nicholls by name, but also the court’s own explanation of its order, provided on June 9, 2000, when the court announced the amendments orally. There the court stated that it had initially concluded that “the Nicholls had a personal right to recovery of attorneys’ fees because they were the personal defendants.” The court amended its order following the realization that only some of the Buchans’ claims were made personally against the Nicholls and others against the estate. The Buchans were not harmed by the June 12 amendments, but were in fact benefit-ted by them. Therefore, the district court lacked jurisdiction to hear the Buchans appeal.
We vacate the judgment of the district court and remand to the bankruptcy court.
VACATE AND REMAND TO THE BANKRUPTCY COURT.
