José A. Zambrana Arroyo, the chapter 7 debtor, appeals the bankruptcy court’s order granting Scotiabank de Puerto Rico (“Scotiabank”) retroactive relief from the automatic stay in order to validate a post-petition foreclosure sale.1 For the reasons set forth below, we conclude that the debt- or is without standing to bring this appeal and therefore DISMISS this appeal.
BACKGROUND
The debtor owned certain real property encumbered by a mortgage held by Scotia-bank. Over a nine-year period, the debtor filed four bankruptcy petitions, each on the eve of foreclosure, to prevent Scotiabank from foreclosing on the property. In the third case, the debtor and Scotiabank entered into a settlement agreement, in which Scotiabank was granted relief from stay, and the debtor was granted a short period of time to try to sell or refinance the property and pay Scotiabank in full. If he failed to do so, Scotiabank could then sell the property. The settlement agreement also provided that the order lifting the automatic stay would be res judicata in any future bankruptcy cases filed within two years. The bankruptcy court approved the settlement agreement, and, shortly thereafter, the debtor voluntarily dismissed the case.
When the debtor failed to pay Scotia-bank in accordance with the settlement agreement, Scotiabank scheduled a foreclosure sale. The day before the scheduled sale, however, the debtor filed his fourth bankruptcy petition, seeking relief under chapter 7. Scotiabank proceeded with the sale and was the successful bidder for the property.
Thereafter, in an abundance of caution, Scotiabank moved for retroactive relief from the automatic stay to validate the foreclosure sale, arguing that it was conducted in reliance on the settlement agreement, which made relief from stay binding in future bankruptcy cases, and urging the bankruptcy court to consider the debtor’s history of serial filings on the eve of foreclosure.2 The chapter trustee did not object, and has filed a “no asset” report. After a hearing, the bankruptcy court granted Scotiabank retroactive relief from the automatic stay. This appeal ensued.
APPELLATE STANDING
Before addressing the merits, we must first consider whether the debtor has *488standing to prosecute this appeal. See Weaver’s Cove Energy, LLC v. R.I. Coastal Res. Mgmt. Council, 589 F.3d 458, 467 (1st Cir.2009) (explaining that court must review party’s standing in order to determine its jurisdiction regardless of whether the parties raise the issue); Pignato v. Dein Host, Inc. (In re Dein Host, Inc.), 835 F.2d 402, 404 (1st Cir.1987) (noting that court is “duty bound” to determine appellate standing); Great Road Serv. Ctr., Inc. v. Golden (In re Great Road Serv. Ctr., Inc.), 304 B.R. 547, 550 (1st Cir. BAP 2004) (“[Questions of standing must be considered sua sponte as it is akin to subject matter jurisdiction.”). “Standing is a ‘threshold question in every federal case, determining the power of the court to entertain the suit.’ ” N.H. Right to Life Political Action Comm. v. Gardner, 99 F.3d 8, 12 (1st Cir.1996) (quoting Warth v. Seldin, 422 U.S. 490, 498, 95 S.Ct. 2197, 45 L.Ed.2d 343 (1975)). If the debtor lacks standing to bring this appeal, then we lack jurisdiction to decide it upon its merits. See United States v. AVX Corp., 962 F.2d 108, 113 (1st Cir.1992).
It is well settled that only a “person aggrieved” has standing to pursue an appeal, and that a “person aggrieved” is one whose pecuniary interests are directly and adversely affected by an order of the bankruptcy court. Thus, a party asserting standing must demonstrate that the bankruptcy court’s order either diminishes his property, increases his burdens, or detrimentally affects his rights. Aja v. Emigrant Funding Corp. (In re Aja), 442 B.R. 857, 861 (1st Cir. BAP 2011); In re Great Road, 304 B.R. at 551.
Normally, it is the trustee, and not the chapter 7 debtor, who possesses standing to appeal from a bankruptcy court order affecting property of the estate. Spenlinhauer v. O’Donnell, 261 F.3d 113, 118 (1st Cir.2001) (citations omitted). “Since title to property of the estate no longer resides in the chapter 7 debtor, the debtor typically lacks any pecuniary interest in the ... disposition of that property.” Id. (citing In re El San Juan Hotel, 809 F.2d 151, 154-55 (1st Cir.1987)). A chapter 7 debtor qualifies as a “person aggrieved” for purposes of appellate standing only if he can demonstrate either: (1) a reasonable possibility of a surplus if the order on appeal is defeated; or (2) that the appealed order adversely affects his discharge. Marmarinos v. DeGiacomo (In re Marmarinos), 464 B.R. 498, 501 n. 1 (1st Cir. BAP 2012) (citing Beaulac v. Tomsic (In re Beaulac), 294 B.R. 815, 820-21 (1st Cir. BAP 2003)).
The debtor has not demonstrated that he has standing to pursue this appeal. He admits he could not benefit personally were we to reverse the court below, as he concedes there is no equity in the property. Moreover, the order at issue has no effect whatsoever on the debtor’s discharge. Accordingly, the debtor cannot show that the order on appeal affects his pecuniary interest or that he is aggrieved in any other cognizable way.
The concurrence would consider that the debtor has standing and would reach the merits of this appeal. But by what standard it would determine standing is unexplained. This is problematic for at least two reasons. First, it is the debtor’s burden to articulate and prove his standing. Second, the debtor has stipulated standing away — agreeing there is insufficient equity in the property even to reach an exemption, and filing a chapter 7, admitting no plan or prospect of saving the property by bankruptcy process.
CONCLUSION
For the reasons set forth above, we conclude that the debtor is without stand*489ing to pursue this appeal and, therefore, this appeal is DISMISSED.
