Purchase-Money Security Interest
What is a purchase-money security interest?
A purchase-money security interest (PMSI) is a lien that secures the very debt incurred to buy the collateral it's attached to — a car lender's claim to the vehicle it financed. The Bankruptcy Code doesn't define the term; it borrows the definition from state law, almost always UCC Article 9 § 9-103. In a Chapter 13 car loan, PMSI status is 1 of 3 conditions the § 1325(a) hanging paragraph requires before it blocks cramdown.
Key takeaways
- A purchase-money security interest (PMSI) secures the debt incurred to buy the very collateral it's secured by; the Bankruptcy Code doesn't define the term itself, borrowing it instead from state law, almost always a state's enactment of UCC Article 9 § 9-103.
- In a Chapter 13 car loan, PMSI status is 1 of 3 conditions — alongside 910-day timing and personal-use vehicle collateral — that the § 1325(a) hanging paragraph requires before it blocks § 506 cramdown; the full three-condition test is covered on the 910-day rule page.
- Outside bankruptcy, PMSI status carries its own reward under UCC § 9-324(a): for goods other than inventory or livestock, a purchase-money lender that perfects its interest within 20 days of the debtor taking possession gets priority over an earlier, conflicting security interest in the same collateral.
- Most states perfect a lien on a motor vehicle by having it noted on the certificate of title under a separate state statute rather than by filing a UCC financing statement, since UCC § 9-311(a)(2) lets a state's certificate-of-title law displace Article 9's ordinary filing rule.
- UCC § 9-103's dual-status, payment-application, and burden-of-proof rules in subsections (e), (f), and (g) each apply only in a transaction other than a consumer-goods transaction, and subsection (h) says that limitation is deliberate — leaving to the courts whether refinancing, cross-collateralization, or a rolled-in trade-in balance costs a consumer car loan its purchase-money status, which is exactly where the negative-equity circuit split lives.
- Courts disagree over whether negative equity rolled into a new car loan survives as protected purchase-money debt: 8 circuits say yes, the Ninth Circuit's 2010 decision in In re Penrod says no, and the outcome can also turn on which state's UCC language governs the loan.
What is a purchase-money security interest?
A purchase-money security interest (PMSI) is a lien that secures the very debt incurred to buy the collateral it's attached to — most commonly, a car lender's claim to the vehicle it financed. The term comes from Article 9 of the Uniform Commercial Code, the body of state law governing secured transactions in personal property. UCC § 9-103(a)(2) defines a "purchase-money obligation" as "an obligation of an obligor incurred as all or part of the price of the collateral or for value given to enable the debtor to acquire rights in or the use of the collateral if the value is in fact so used." § 9-103(a)(1) then defines "purchase-money collateral" as the goods that secure that obligation. Put together: a security interest is a PMSI when the money it secures is the money that bought the thing it's secured by.
That's narrower than "any lien on something a debtor owns." A bank loan secured by a car the borrower already owned before taking out the loan isn't a PMSI, even though the collateral is identical — the debt didn't fund the purchase. The distinction matters in two places: which creditor wins when two liens compete for the same collateral outside bankruptcy, and, inside a Chapter 13 case, whether a car loan can be reduced to the vehicle's current value at all.
Does the Bankruptcy Code define a PMSI, or does it come from somewhere else?
It comes from somewhere else. Neither 11 U.S.C. § 101, the Code's general definitions section, nor § 1325 itself defines "purchase money security interest" — the phrase is used in the § 1325(a) hanging paragraph without being spelled out. Courts fill the gap by importing the definition from state law, almost always the version of UCC Article 9 the relevant state has enacted — an application of the general rule in Butner v. United States, 440 U.S. 48, 54–57 (1979), that property interests are created and defined by state law unless a federal interest requires otherwise. The Ninth Circuit ran exactly that sequence in In re Penrod, 611 F.3d 1158 (9th Cir. 2010), reaching California Commercial Code § 9103 to answer a federal Chapter 13 question. That means whether a specific auto loan qualifies as a PMSI can turn on state commercial law as much as on the Bankruptcy Code — which is also why the hardest disputes over PMSI status, covered below, end up varying by state and by circuit instead of resolving to one national rule.
Why does PMSI status matter for a Chapter 13 car loan?
Because it's one of three conditions that together block a Chapter 13 plan from reducing a car loan to the vehicle's current value. The hanging paragraph at the end of 11 U.S.C. § 1325(a) reads, in relevant part:
> "For purposes of paragraph (5), section 506 shall not apply to a claim described in that paragraph if the creditor has a purchase money security interest securing the debt that is the subject of the claim, the debt was incurred within the 910-day period preceding the date of the filing of the petition, and the collateral for that debt consists of a motor vehicle (as defined in section 30102 of title 49) acquired for the personal use of the debtor..."
Three things have to be true at once: a purchase-money security interest, timing within 910 days of filing, and collateral that's a personal-use motor vehicle. PMSI status is the first of those three and doesn't substitute for the others — a loan can be well inside the 910-day window and secure a personal-use car, and still fail to block cramdown if the debt itself isn't purchase-money (for example, a separate loan secured by a car the debtor already owned). The full three-condition test is covered on the 910-day rule page; how cramdown works once § 506 does apply is covered on the cramdown page.
What is a PMSI worth outside bankruptcy?
Priority over a competing lien on the same collateral. UCC § 9-324(a) gives a perfected purchase-money security interest in goods other than inventory or livestock "priority over a conflicting security interest in the same goods... if the purchase-money security interest is perfected when the debtor receives possession of the collateral or within 20 days thereafter." A lender that finances a purchase and perfects its lien within 20 days of the buyer taking possession jumps ahead of an earlier, unrelated lien the buyer's other creditors might already hold — a "super-priority" that exists to make purchase-money financing safe to extend in the first place.
For a car, perfection usually isn't a UCC filing at all. UCC § 9-311(a)(2) lets a state's certificate-of-title statute displace Article 9's ordinary filing rule for vehicles: in the uniform text, (a)(2) is a bracketed placeholder each legislature fills in with its own statute "covering automobiles, trailers, mobile homes, boats, farm tractors, or the like, which provides for a security interest to be indicated on a certificate of title." That's why a lien on a financed car shows up as a notation on the certificate of title rather than in a UCC filing database — the notation is the act of perfection, not paperwork alongside it.
| Scenario | Purchase-money obligation? |
|---|---|
| Loan proceeds used entirely to pay the price of the vehicle | Yes |
| A separate loan, secured by a car the debtor already owned before borrowing | No — the debt didn't fund the purchase of that collateral |
| A home-equity loan later used to buy a car, but secured by the house | No — the collateral securing the debt isn't what the debt purchased |
| Rolled-in negative equity from a prior trade-in, added to a new-car loan | Circuit-split — see below |
| Refinancing the same purchase-money loan with no new money advanced | Unsettled for a car loan; UCC § 9-103(f)'s clear preservation rule applies only outside consumer-goods transactions |
What can cost a loan its purchase-money status?
Adding debt to the loan that didn't go toward the collateral's price, or securing the debt with collateral the loan didn't buy. UCC § 9-103(f) has a clean answer for this in a non-consumer transaction: a purchase-money security interest "does not lose its status as such" even if the collateral also secures a non-purchase-money obligation, even if other collateral also secures the purchase-money obligation, and even if the obligation is later "renewed, refinanced, consolidated, or restructured." That's the "dual-status" approach — mixing in some non-purchase-money debt doesn't automatically taint the whole loan.
The catch is in the opening words of subsection (f) itself. That clean rule, and the related payment-application and burden-of-proof rules in (e) and (g), each begin "In a transaction other than a consumer-goods transaction" — and a car bought for personal use is a consumer-goods transaction. Subsection (h) then says the limitation is deliberate: it "is intended to leave to the court the determination of the proper rules in consumer-goods transactions," and a court "may not infer from that limitation the nature of the proper rule in consumer-goods transactions and may continue to apply established approaches." So Article 9's drafters left the exact question that matters most for a car loan to the courts — while telling those courts the omission is not itself an argument in either direction, and that pre-revision case law survives it. That's the statutory root of the split described next.
Does rolled-in negative equity survive as purchase-money debt?
Mostly, but not everywhere, and it's unresolved at the U.S. Supreme Court level. It's common for a car loan to roll in "negative equity" — the amount still owed on a trade-in worth less than its payoff — along with the new vehicle's price, taxes, and fees into one balance. Because § 9-103(h) leaves consumer-goods purchase-money questions to the courts, federal circuits have split over whether that rolled-in balance is still purchase-money debt.
| Position | Courts | Example |
|---|---|---|
| Negative equity is part of the protected purchase-money debt | 8 circuits: Second, Fourth, Fifth, Sixth, Seventh, Eighth, Tenth, Eleventh | In re Peaslee, 585 F.3d 53 (2d Cir. 2009) |
| Negative equity is not purchase-money debt | Ninth Circuit | In re Penrod, 611 F.3d 1158 (9th Cir. 2010) |
Because the underlying question is a matter of state commercial law as much as federal bankruptcy law, the same facts can also come out differently depending on which state's UCC language governs the loan, independent of which circuit hears the case. The full list of circuit citations is on the 910-day rule page, and how this plays out for a specific underwater 910-day loan is worked through on my 910-day car is underwater. Anyone whose loan included a rolled-in trade-in balance should raise it directly with the attorney handling the case rather than assume either outcome.
This page explains what a purchase-money security interest is and how courts and the UCC treat it generally; it isn't legal advice about whether a specific loan qualifies. For how PMSI status fits into financing decisions while a Chapter 13 case is open, see the Chapter 13 car loan pillar page.
Common questions
Is a purchase-money security interest the same thing as having a lien noted on a car's title?
No, they're two different layers. A PMSI is a legal category based on why the debt was incurred — that it funded the purchase of the collateral. A title notation is how most states perfect that lien so it's enforceable against other creditors, under UCC § 9-311(a)(2). A title notation can secure a PMSI, but it can equally secure a non-purchase-money loan, like a title loan taken against a car the borrower already owns free and clear.
Does a PMSI have to be held by the dealer, or can a bank hold one too?
It doesn't have to be the dealer. UCC § 9-103(a)(2) defines a purchase-money obligation as one incurred for the price of the collateral "or for value given to enable the debtor to acquire rights in" it — two separate routes. A bank or finance company that advances funds to the buyer qualifies under the second. A dealer that sells on credit qualifies under the first, and can then assign that retail installment contract, and the security interest with it, to a finance company; that is how the loan in In re Penrod, 611 F.3d 1158 (9th Cir. 2010), reached the creditor that litigated it.
Does refinancing a car loan destroy its purchase-money status?
There's no clean answer for a car loan specifically. UCC § 9-103(f) says a purchase-money security interest doesn't lose its status just because the obligation was "renewed, refinanced, consolidated, or restructured" — but subsection (f) applies only to transactions other than consumer-goods transactions. A car bought for personal use is a consumer-goods transaction, so § 9-103(h) leaves the refinancing question to the courts rather than answering it in the statute.
Does trading in a vehicle with positive equity raise the same purchase-money question as rolled-in negative equity does?
Not in the same way. The negative-equity dispute exists because that amount is debt left over from a different transaction, added to what the new loan otherwise financed. A trade-in with positive equity works the opposite direction — it reduces the amount the buyer has to borrow for the new vehicle rather than adding unrelated debt on top of it, so it doesn't raise the same question of whether the whole balance was incurred for the price of the new car.
Is "purchase-money security interest" defined exactly the same way in every state?
Close, but not guaranteed to be identical. Every state has enacted its own version of UCC Article 9, and while the definitions in § 9-103 are meant to be uniform, each legislature adopts, numbers, and occasionally amends the text independently. Confirming the exact wording in the state whose law governs a given loan is a job for the loan documents and an attorney, not an assumption that every state's § 9-103 reads word for word the same.
