BARRON, Chief Judge. Builders Holding Company 

("Builders"),1 a general contractor, filed for bankruptcy in the 

United States Bankruptcy Court for the District of Puerto Rico in 

August 2016. Builders then filed an adverse action against the 

Puerto Rico Infrastructure Financing Authority ("Financing 

Authority"), which had hired Builders for construction projects,

and Oriental Bank, with which Builders had a deposit account. 

Builders's surety, MAPFRE PRAICO Insurance Company and Endurance 

Assurance Corporation ("MAPFRE"), intervened in that adverse 

action and filed its own claims against Oriental Bank. At the 

same time, Oriental Bank filed counterclaims in the adverse action 

against MAPFRE and Builders. All the claims in the adverse action 

pertained to funds -- totaling more than $450,000 -- that the 

Financing Authority had directly deposited in Builders's deposit 

account with Oriental Bank and that Oriental Bank had taken from 

that account to set off a debt that Builders owed to it. 

The Bankruptcy Court granted summary judgment against 

Oriental Bank on all the claims asserted against it.2 Oriental 

Bank appealed that ruling to the District Court, which affirmed. 

1 References to Builders throughout the opinion refer to the 

Builders Holding Company and its predecessor entities.

2 The Bankruptcy Court also granted summary judgment in favor 

of the Financing Authority as to Builders's claims against it.

We vacate and remand the grant of summary judgment against Oriental 

Bank on all the claims.

I.

Builders offers general-contractor services for 

construction projects. It entered into an indemnification 

agreement with MAPFRE on August 5, 2010. 

The agreement provided that MAPFRE would issue surety 

bonds to guarantee the payment of labor and materials for 

Builders's construction projects and that Builders would hold 

MAPFRE harmless and indemnify MAPFRE against any and all loss from 

the surety bonds that it issued. The agreement further provided 

that Builders would assign "all payments received for or on account 

of any contract" to a trust that would "inure to the benefit of 

[the] surety for any liability or loss it may have or sustain under 

any bond" (capitalization adjusted). 

MAPFRE registered the agreement as a financing statement

at the Puerto Rico Department of State pursuant to Puerto Rico 

law. The parties do not dispute that MAPFRE's registration of the 

agreement perfected MAPFRE's security interest in Builders's 

accounts receivable. 

A number of years passed, and, on November 14, 2013, 

Builders executed a Cash Management Agreement with Oriental Bank. 

The agreement enabled Builders to use an existing charge account 
- 5 -

at Oriental Bank as its operational account for business income 

and expenses ("Deposit Account").

On December 26, 2014, Builders opened two lines of credit 

for business operational expenses with Oriental Bank pursuant to 

a Line of Credit Agreement. One line of credit was for $675,000. 

The other was for $500,000. 

The lines of credit were secured by Builders's accounts 

receivable and Deposit Account.3 Oriental Bank recorded its 

security interest in this collateral on December 30, 2014. 

In September 2015, the Financing Authority contracted 

with Builders for construction projects in the town of Cabo Rojo. 

MAPFRE acted as surety for this contract and issued performance 

and payment bonds. The bonds had a maximum of $3,070,480. The 

Financing Authority was named as obligee on the bonds and Builders

was named as the principal.

Builders's lines of credit with Oriental Bank matured

approximately three months later. Thus, as of December 26, 2015, 

Builders was required to repay Oriental Bank the entirety of the 

sum due on the lines of credit, which was more than $450,000.

Then, on February 16, 2016, MAPFRE sent a letter to the 

Financing Authority. The letter informed the Financing Authority 

3 Builders represented to Oriental Bank that the accounts 

receivable were not otherwise encumbered -- even though the 

accounts receivable were subject to MAPFRE's security interest.
- 6 -

that MAPFRE had received claims from contractors on Builders's 

projects for payment for the cost of labor or materials under the 

surety bonds that MAPFRE had issued for Builders's projects with 

the Commonwealth. The letter further informed the Financing 

Authority that, per the terms of MAPFRE's indemnification 

agreement with Builders, payments from the Financing Authority for 

the costs of Builders's construction projects in Cabo Rojo were to 

be sent to MAPFRE and made payable jointly to Builders and MAPFRE. 

Approximately one week later, Builders also informed the Financing 

Authority that it should send all future payments for Builders's

work on the construction projects in Cabo Rojo to MAPFRE and that 

the payments should be made out jointly to MAPFRE and Builders. 

Notwithstanding these instructions, the Financing 

Authority on May 23, 2016, deposited $537,924.18 directly into 

Builders's Deposit Account at Oriental Bank. The Financing 

Authority did not in doing so make any payment to MAPFRE. At the 

time of the Financing Authority's deposit of the more than $500,000 

into Builders's Deposit Account, Builders had yet to repay in full 

the amount that it owed to Oriental Bank on its lines of credit. 

Under Puerto Rico law, a bank with "a security interest 

in a deposit account perfected by control . . . may apply the 

balance of the deposit account to the obligation secured by the 

deposit account." P.R. Laws Ann. tit. 19, § 2367(a)(4). Acting 

pursuant to that provision, Oriental Bank applied $464,757.60 from 
- 7 -

the balance deposited into Builders's Deposit Account against the 

outstanding balance on Builders's lines of credit. 

The following day, the Financing Authority 

unsuccessfully attempted to reverse the deposit that it had made 

to Builders's Deposit Account with Oriental Bank. Moreover, the 

Financing Authority sent Oriental Bank a letter the following week 

that explained its error in not making any payment to MAPFRE and 

instead making the deposit directly into Builders's Deposit 

Account. Oriental Bank did not return the money that it had taken 

from Builders's Deposit Account to use as a set-off in connection 

with the debt that Builders owed it. 

The Financing Authority followed up with another letter 

to Oriental Bank on December 12, 2017, in which the Financing 

Authority again requested that the funds in question be turned 

over to MAPFRE. Oriental Bank again did not do so. 

MAPFRE sent its own letter to Oriental Bank on July 1, 

2016, in which it requested that Oriental Bank send to MAPFRE the 

money that it had taken from Builders's Deposit Account as a setoff of Builders's debt to Oriental Bank. Builders sent a similar 

letter of its own. Oriental Bank did not take the action requested 

in either letter. 

Builders filed for bankruptcy under Chapter 11 of the 

Bankruptcy Code on August 20, 2016. Builders then brought an 
- 8 -

adverse action against the Financing Authority and Oriental Bank 

on January 12, 2017. 

The complaint set forth four claims under §§ 542 and 543

of the Bankruptcy Code. Those provisions of the Code require all 

the debtor's property to be delivered to the trustee.4 

Counts One and Two of Builders's complaint allege, 

respectively, that under §§ 542 and 543, the Financing Authority 

is required to turn over the funds Builders alleges that the 

Financing Authority still owes it for the construction projects in 

Cabo Rojo. Builders alleges in those two counts that the Financing 

Authority did not satisfy its obligations to Builders by directly 

depositing funds into Builders's Deposit Account because Builders

had instructed the Financing Authority to send those funds directly 

to MAPFRE. Counts Four and Five allege, under §§ 542 and 543 of 

the Bankruptcy Code, that Oriental Bank is required to return the 

funds that it took from Builders's Deposit Account as a set-off, 

4 11 U.S.C. § 542(a) provides that:

[A]n entity, other than a custodian, in 

possession, custody, or control . . . of 

property that the trustee may use, sell, or 

lease under [§] 363 of this title, or that the 

debtor may exempt under [§] 522 of this title, 

shall deliver to the trustee, and account for, 

such property or the value of such property, 

unless such property is of inconsequential 

value or benefit to the estate.

11 U.S.C. § 543(b) provides similarly for "custodians" of 

such property.
- 9 -

so that those funds can be delivered to MAPFRE, which the complaint 

further alleges has a senior claim as to those funds. Count Three 

of the complaint alleges that "[u]nder Puerto Rico [l]aw[,] the 

wrongly made payment does not extinguish the obligation" that the 

Financing Authority has under its construction contract with 

Builders for the construction projects in Cabo Rojo, such that the 

Financing Authority still owes Builders a debt under that contract 

that must be paid. 

Oriental Bank moved to dismiss Builders's complaint 

under Federal Rule of Civil Procedure 12(b)(6) on February 6, 2017. 

The Bankruptcy Court denied the motion.

On April 3, 2017, MAPFRE intervened in Builders's 

adverse action, and on May 26, 2017, MAPFRE filed its own complaint 

against Builders, the Financing Authority, and Oriental Bank. 

MAPFRE requested in that complaint, among other things, that 

Oriental Bank turn over the funds that had been deposited by the 

Financing Authority in Builders's Deposit Account. 

Following the Bankruptcy Court's denial of Oriental 

Bank's motion to dismiss, Oriental Bank answered Builders's 

complaint on June 2, 2017. As part of the answer, Oriental Bank 

brought a counterclaim against Builders, in which Oriental Bank 

alleged that, under Puerto Rico law, it had a valid, enforceable 

lien against Builders's accounts receivable and Deposit Account 
- 10 -

and thus that it was entitled under 11 U.S.C. § 553 to set off the 

amount that Builders owed to it on Builders's lines of credit.5 

That same day, Oriental Bank answered MAPFRE's 

intervenor complaint and brought a counterclaim against MAPFRE. 

Oriental Bank's counterclaim alleged that Oriental Bank's secured 

interest in Builders's accounts receivable and Deposit Account was 

senior to that of MAPFRE, such that Oriental Bank was entitled to 

keep the funds that it had taken from Builders's Deposit Account 

as a set-off of the debt owed to it by Builders. 

The Financing Authority answered Builders's and MAPFRE's 

complaints on June 2, 2017. MAPFRE answered Oriental Bank's 

counterclaim on June 26, 2017. And, finally, on July 11, 2017, 

Builders answered both Oriental Bank's counterclaim as well as 

MAPFRE's intervenor complaint. 

Thereafter, motions for summary judgment were filed, and 

Builders moved to convert its Chapter 11 bankruptcy petition to a 

Chapter 7 petition. The Bankruptcy Court granted that motion on 

5 11 U.S.C. § 553(a) provides, with a few exceptions that are 

not relevant to this appeal, that:

[The Bankruptcy Code] does not affect any 

right of a creditor to offset a mutual debt 

owing by such creditor to the debtor that 

arose before the commencement of the case 

under this title against a claim of such 

creditor against the debtor that arose before 

the commencement of the case.
- 11 -

April 27, 2018, and a trustee was appointed. The trustee elected 

to join the summary judgment motion that MAPFRE had filed. 

In response to the summary judgment motions, the 

Bankruptcy Court on March 31, 2020, granted summary judgment to 

MAPFRE and the trustee on their claims against Oriental Bank, 

granted summary judgment in favor of MAPFRE and the trustee on the 

claims that Oriental Bank asserted against those parties, and

granted summary judgment in favor of the Financing Authority as to 

the claims asserted against it by Builders and MAPFRE. See

Rentas v. Oriental Bank (In re Builders Holding Co.), 617 B.R. 

414, 428-29 (Bankr. D.P.R. 2020). In so ruling, the Bankruptcy 

Court held that Oriental Bank's set-off was not permitted under 

the Bankruptcy Code because the Financing Authority had made a 

payment to Builders that was a payment in error under Article 1795 

of the Puerto Rico Civil Code, P.R. Laws Ann. tit. 31, § 5121,6

and Oriental Bank was thus required to return the funds mistakenly 

paid to Builders's Deposit Account to the payor, the Financing 

Authority, which had been instructed by MAPFRE and Builders to 

make the payment directly to MAPFRE. In re Builders Holding Co., 

617 B.R. at 427-28.

6 Article 1795, translated, states that "[i]f a thing is 

received when there was no right to claim it and which, through an 

error, has been unduly delivered, there arises an obligation to 

restore the same." P.R. Laws Ann. tit. 31, § 5121. 
- 12 -

On April 14, 2020, Oriental Bank filed a motion for 

reconsideration with the Bankruptcy Court. The Bankruptcy Court 

denied the motion on November 5, 2020. See In re Builders Holding 

Co., Ch. 11 Case No. 16-06643, Adv. No. 17-00012, 2020 WL 6538587,

at *2 (Bankr. D.P.R. Nov. 5, 2020).

Oriental Bank then appealed the Bankruptcy Court's 

rulings against it to the United States District Court for the 

District of Puerto Rico. The District Court affirmed the 

Bankruptcy Court's grants of summary judgment on March 4, 2021, 

finding that the Bankruptcy Court correctly applied Article 1795. 

See Oriental Bank v. Builders Holding Co., 626 B.R. 1, 11-12

(D.P.R. 2021). Oriental Bank timely appealed from that ruling.7

II.

The Bankruptcy Court held that 11 U.S.C. § 553 did not 

permit Oriental Bank to use the funds that the Financing Authority 

had deposited into Builders's Deposit Account as a set-off for the 

debt that Builders owed to it. In re Builders Holding Co., 617 

B.R. at 427-28. The Bankruptcy Court explained that this was so 

because, under § 553(a), a creditor may set off funds owed to it 

7 We note that the parties appear to treat the Bankruptcy 

Court as having granted summary judgment in favor of the Financing 

Authority on claims against it by Oriental Bank. It does not 

appear, however, that Oriental Bank brought any such claims. In 

addition, we note, MAPFRE and the trustee have not appealed the 

rulings granting summary judgment in favor of the Financing 

Authority on its claims against that entity. 
- 13 -

by a debtor in bankruptcy if the creditor would have been able to 

do so if the debtor had not filed for bankruptcy. And, the 

Bankruptcy Court concluded, if Builders had not filed for 

bankruptcy, Oriental Bank would not have had any right under Puerto 

Rico law, given Article 1795, to the funds that the Financing 

Authority had deposited directly in Builders's Deposit Account. 

Id. It was on that basis, and that basis alone, that the Bankruptcy 

Court granted summary judgment against Oriental Bank on all the 

claims at issue in the adverse action that involved Oriental Bank. 

The District Court rejected Oriental Bank's challenge to that 

ruling.

Litigants in a bankruptcy proceeding ordinarily "must 

first appeal to the district court" and then "courts of appeals 

are . . . available as a second tier of appellate review," but, 

"[d]espite this sequencing, we cede no special deference to the 

determinations made by the first-tier tribunal . . . [and] assess 

the bankruptcy court's decision directly." City Sanitation, LLC

v. Allied Waste Servs. Mass., LLC (In re Am. Cartage, Inc.), 656 

F.3d 82, 87 (1st Cir. 2011). We thus review the Bankruptcy Court's 

grant of summary judgment de novo. See Desmond v. Varrasso (In re 

Varrasso), 37 F.3d 760, 763 (1st Cir. 1994).8

8 MAPFRE contends that we should review the Bankruptcy Court's 

determination that the set-off here was not permissible under the 

Bankruptcy Code for an abuse of discretion. Notwithstanding 

whether that would be the appropriate standard of review in some 
- 14 -

In challenging the grant of summary judgment to the 

Financing Authority, Oriental Bank argues to us that "the Financing 

Authority did not show or prove the requirements to establish a 

cause of payment made in error." See P.R. Laws Ann. tit. 31, 

§ 5126 ("The proof of payment is incumbent upon the person who 

claims to have made the same. He shall also be obliged to prove 

the error under which he made it."). For that reason, Oriental 

Bank contends, the Bankruptcy Court erred in ruling that Oriental 

Bank was obligated to return the money that it had set off against 

Builders's debt to it. 

According to the Supreme Court of Puerto Rico, 

Article 1795 applies when: (1) a "payment [is] produced for the 

purpose of extinguishing an obligation;" (2) "the payment made 

does not have a just cause, that is, that there is no legal 

obligation between the payer and the receiver, or if the obligation 

exists, that it [is] for less than the amount paid;" and (3) "the 

payment was made by mistake and not out of sheer generosity or any 

other reason." Puerto Rico v. Crespo Torres, 180 P.R. Dec. 776, 

circumstances when § 553 is at issue, here, we conclude that the 

Bankruptcy Court's application of the payment-in-error doctrine 

was legally incorrect. As such, even if the standard were abuse 

of discretion, we would still reverse the Bankruptcy Court's grant 

of summary judgment and remand for further proceedings. See

Saka v. Holder, 741 F.3d 244, 250 (1st Cir. 2013) ("Any error of 

law is, inherently, an abuse of discretion.").
- 15 -

793-94 (2011).9 Thus, given how the Supreme Court of Puerto Rico 

has construed Article 1795, we must identify the "receiver" of the 

"payment" from the "payer."

The complication for the Financing Authority here is 

that it is not claiming that, under Article 1795, Builders is 

required to return a "payment" that Builders "received" from the 

Financing Authority. The Financing Authority is claiming that, 

under that doctrine, Oriental Bank is required to return a 

"payment" that Oriental Bank "received" from the Financing 

Authority. 

The Financing Authority did not make a "payment" to 

Oriental Bank in its own right, however. The Financing Authority 

made a "payment" to Builders, which had a deposit account with 

Oriental Bank, by transferring its funds directly into that 

account. Thus, strictly speaking, only Builders made a "payment" 

that Oriental Bank itself "received" (though Builders made the 

payment to Oriental Bank only because Builders received funds 

through the payment that it had received from the Financing 

Authority). 

The consequence of this chain of transactions -- and the 

party from which the Financing Authority is seeking recoupment --

9 The Supreme Court of Puerto Rico's opinion in this case was 

written in Spanish. Oriental Bank thus submitted a certified 

translation of this case in its briefing to us, and it is that

translation that we quote in this opinion.
- 16 -

is that the question presented here is whether Article 1795 applies

even when there is this level of remove between the "payer" and 

the "receiver," Crespo Torres, 180 P.R. Dec. at 793-94; see Phoung 

Luc v. Wyndham Mgmt. Corp., 496 F.3d 85, 88 (1st Cir. 2007) (When 

"apply[ing] the state's law on substantive issues[,] . . . 'we are 

bound by the teachings of the state's highest court.'" (quoting N. 

Am. Specialty Ins. Co. v. Lapalme, 258 F.3d 35, 37–38 (1st Cir.

2001))); Carrasquillo-Serrano v. Municipality of Canovanas, 991 

F.3d 32, 40 (1st Cir. 2021) (explaining that for purposes akin to 

ours' here, "Puerto Rico is the functional equivalent of a 

state[,] . . . [and] an on-point decision of the Puerto Rico 

Supreme Court normally will control" (quoting Gonzalez Figueroa v. 

J.C. Penney P.R., Inc., 568 F.3d 313, 318 (1st Cir. 2009))). It 

is not at all natural, however, to refer to a third party to a 

transfer of funds -- as Oriental Bank is here, given that the 

transfer, at least initially, was only between the Financing 

Authority and Builders -- as the "receiver" of the funds from that 

transfer by the "payer." Yet, neither MAPFRE nor the Financing 

Authority develops an argument to us as to how we may construe 

Article 1795 to apply to situations like this one beyond merely 

asserting (unpersuasively) that the face of the statute compels 

the conclusion. Nor does either the Bankruptcy Court or the 

District Court explain why such a construction would be correct. 

We thus conclude that the Bankruptcy Court was wrong to find that 
- 17 -

Article 1795 compelled the return of funds Oriental Bank set off 

against Builders's debt to it. See S. Commons Condo. Ass'n v. 

Charlie Arment Trucking, Inc., 775 F.3d 82, 91 (1st Cir. 2014) 

(noting that plaintiffs, "having chosen a federal forum to seek 

relief that depends at least in part on the meaning of state law, 

should not 'expect the federal court to steer state law into 

unprecedented configurations'" (quoting Santiago v. Sherwin 

Williams Co., 3 F.3d 546, 549 (1st Cir. 1993))); see also Phoung 

Luc, 496 F.3d at 88 ("As a federal court, we will not create new 

rules or significantly expand existing rules. We leave those tasks 

to the [Commonwealth] courts.").10

That said, there remains a question whether the set-off 

that Oriental Bank asserts here is senior to the secured interest 

that MAPFRE has in the same collateral under Puerto Rico law, as 

well as the seemingly fact-laden question (to the extent that it 

is contested) as to whether Oriental Bank's set-off was a "mutual 

debt," 11 U.S.C. § 553(a); see In re Pub. Serv. Co. of N.H., 884 

F.2d 11, 14 (1st Cir. 1989) ("[A] set[-]off may flourish in 

10 We note that neither MAPFRE nor the Financing Authority 

asks us to certify this question to the Supreme Court of Puerto 

Rico, even though the Financing Authority identifies no Puerto 

Rico court case in which Article 1795 has been applied in a 

circumstance in which the party relying on the payment-in-error 

doctrine seeks to recover funds that were paid to a third party 

pursuant to a transfer that was otherwise valid when made (as is 

seemingly the case with the transfer from Builders to Oriental 

Bank).
- 18 -

bankruptcy proceedings only where mutuality of obligation exists: 

a prepetition debt, i.e., a debt which arose prior to commencement 

of the bankruptcy case, is owed by Creditor A to Debtor, while at 

the same time Creditor A has some claim against Debtor which 

likewise arose prior to commencement of the bankruptcy case."). 

In addition, § 553 of the Bankruptcy Code remains available only 

if Oriental Bank's set-off is otherwise valid under Puerto Rico 

law, which may implicate other doctrines such as the doctrine of 

unjust enrichment. See Gov't of Puerto Rico v. Carpenter Co., 442 

F. Supp. 3d 464, 476-77 (D.P.R. 2020) (describing the "civil law 

equity doctrine" of unjust enrichment as recognized by Puerto 

Rico). We thus remand this case to the Bankruptcy Court, see

Grella v. Salem Five Cent Sav. Bank, 42 F.3d 26, 36 (1st Cir. 

1994), for further proceedings in which those questions may be 

addressed, including by determining whether the proper course may 

be to certify to the Supreme Court of Puerto Rico any question of 

Puerto Rico law that may be implicated by what remains to be 

decided. 

III.

For these reasons, we vacate the grant of summary 

judgment against Oriental Bank as to the claims asserted against 

it that are at issue in this appeal and the grant of summary 

judgment in favor of Builders and MAPFRE on Oriental Bank's claims 

against those parties. We remand for further proceedings 
- 19 -

consistent with this opinion. The parties shall bear their own 

costs.
