When a client brings me a deficiency demand, the story behind it is nearly always the same. Payments fell behind. The lender took the equipment, the fleet, or the vehicle. The collateral got sold. Then the letter showed up demanding the deficiency: the gap between what the sale produced and what was owed, plus fees and costs.
Most people pay it, or default into a judgment on it, because the number looks like arithmetic.
It isn’t arithmetic. It’s a question about how the sale was conducted, and Minnesota’s Uniform Commercial Code puts the burden of that question squarely on the party that ran the sale.
One sentence governs the whole dispute
Minn. Stat. § 336.9-610 says it plainly:
Every aspect of a disposition of collateral, including the method, manner, time, place, and other terms, must be commercially reasonable.
Every aspect. People hear “the price must be reasonable” and stop there. The statute doesn’t. It covers the method, the manner, the time, the place, and the other terms. A secured party may sell, lease, license, or otherwise dispose of collateral after default, but I measure the whole process against that standard, and so will a court. This is Article 9 of the UCC as adopted in Minnesota, and it reaches secured transactions in personal property generally: vehicles, equipment, inventory, accounts, business assets.
Commercial reasonableness is judged on the process, not solely the outcome. A low price alone doesn’t establish a violation. A low price produced by a careless process usually does. I look for the same defects in every sale file, because the same defects keep showing up:
- No notification, or a defective one. Article 9 requires the secured party to send an authenticated notification of disposition before selling, with specific content and timing requirements that differ between consumer-goods and commercial transactions. It’s the most common defect I find, and you can check it from the file.
- A wholesale dump when a retail market existed: a late-model vehicle run through a dealer-only auction, or specialized equipment liquidated at general auction instead of through the trade channel where that equipment actually sells.
- No meaningful marketing. No advertising, no exposure to likely buyers, no time on market.
- Collateral sold dirty, incomplete, or non-functional when modest preparation would have moved the price substantially.
- Timing picked for the lender’s convenience: the worst point in a seasonal market, or an immediate sale when waiting weeks would have produced a materially better result.
- Self-dealing. The secured party or an affiliate buying the collateral. Article 9 restricts private-sale purchases by the secured party for good reason, and I’ve yet to see one of these transactions survive scrutiny comfortably.
- Improper application of the proceeds: costs and fees charged against the sale that neither the agreement nor the statute permits.
The statute tells you who has to prove what
A commercially unreasonable disposition can reduce or eliminate the deficiency, and the Code says how, in so many words. For transactions other than consumer transactions, Minn. Stat. § 336.9-626(a) supplies the rules:
(1) A secured party need not prove compliance with the provisions of this part relating to collection, enforcement, disposition, or acceptance unless the debtor or a secondary obligor places the secured party’s compliance in issue.
(2) If the secured party’s compliance is placed in issue, the secured party has the burden of establishing that the collection, enforcement, disposition, or acceptance was conducted in accordance with this part.
Read that sequence the way I read it. The borrower doesn’t have to prove the sale was unreasonable. The borrower has to raise the issue, and then the burden sits with the party that ran the sale.
Then comes the part that does the damage. Under § 336.9-626(a)(3), a secured party that fails to prove compliance sees the deficiency limited to the amount by which the secured obligation, expenses, and attorney fees exceed the greater of (A) the proceeds actually realized, or (B) “the amount of proceeds that would have been realized had the noncomplying secured party proceeded in accordance with” Article 9.
And (B) is presumed to be the whole debt. Subsection (a)(4):
For purposes of paragraph (3)(B), the amount of proceeds that would have been realized is equal to the sum of the secured obligation, expenses, and attorneys fees unless the secured party proves that the amount is less than that sum.
Work that through. If the lender can’t prove compliance, the law presumes a compliant sale would have produced enough to pay the debt in full. That leaves a deficiency of zero, and it’s the lender’s burden to prove otherwise. That’s the rebuttable presumption rule. It’s why I tell clients the sale file decides these cases.
Consumer transactions are deliberately left open, and nobody gets to argue from the omission. Section 336.9-626(b):
The limitation of the rules in subsection (a) to transactions other than consumer transactions is intended to leave to the court the determination of the proper rules in consumer transactions. The court may not infer from that limitation the nature of the proper rule in consumer transactions and may continue to apply established approaches.
So here’s where that leaves you. In a commercial deficiency case, Article 9 tells you the burden and the presumption. In a consumer transaction, the Code declines to answer, and neither side gets to claim the answer follows from the commercial rule.
Consumer goods collateral does carry one express floor. Under Minn. Stat. § 336.9-625(c)(2), where the collateral is consumer goods, a debtor or secondary obligor may recover for a secured party’s noncompliance “in any event an amount not less than the credit service charge plus ten percent of the principal amount of the obligation or the time-price differential plus ten percent of the cash price.”
And the debtor may have a claim, not just a defense. Section 336.9-625(b) makes a noncomplying party “liable for damages in the amount of any loss caused by a failure to comply,” which “may include loss resulting from the debtor’s inability to obtain, or increased costs of, alternative financing.” Subsection (d) is the limit on double recovery: a debtor whose deficiency is eliminated or reduced under § 336.9-626 “may not otherwise recover under subsection (b)” for the same noncompliance, though a debtor whose deficiency is eliminated may still recover for the loss of a surplus.
Guarantors have the same defenses, usually
This point gets missed all the time. A deficiency claim is frequently brought against the guarantor instead of the defunct business, and the guarantor generally stands in a position to raise the commercial unreasonableness of the disposition.
Unless it was waived. Guaranty agreements routinely include waivers of defenses, and whether a particular waiver reaches this one turns on the language and the transaction type, with limits on what Article 9 lets anyone waive in advance. If you signed a personal guaranty, my fuller treatment is here.
One more boundary line: don’t apply Article 9 analysis to a house. Real estate mortgage foreclosure in Minnesota is a separate body of law, and the availability of a deficiency after foreclosure turns on Minn. Stat. § 582.30 and on how the foreclosure was conducted. Different notice rules, different timelines, different deficiency consequences. A mixed-collateral loan secured by both the building and the equipment needs both analyses.
What I tell people who receive a deficiency demand
Don’t pay it, and don’t ignore it. Both get expensive.
- Demand the entire file in writing. The security agreement, the notification of disposition and proof of how it was sent, the sale documents, all marketing materials, the bidder or attendee record, the buyer’s identity, and a full accounting of proceeds, costs, and fees.
- Check the notification first. Was it sent? To the right address? With the required content? Within the required time? To the guarantor too? That one question resolves a large share of these disputes.
- Figure out what the collateral was worth. Auction result versus retail book value versus comparable sales. A large gap is where the argument starts, not where it ends.
- Ask who bought it. A sale to the lender, an affiliate, or a repeat insider buyer changes the analysis.
- Audit the arithmetic. Repossession and storage charges, attorney fees, and rate calculations are wrong more often than anyone expects.
- Watch the clock. Deficiency claims are subject to limitations periods (see my Minnesota limitations overview), and a default judgment entered against you starts a different set of problems.
If a judgment’s already been entered and you never got the suit papers, that’s a separate and often stronger avenue than the deficiency defense itself. I wrote about the clock on challenging judgments entered without jurisdiction here.
For secured parties, the same statute is a compliance checklist, and following it costs far less than litigating it. Send the notification correctly every time and keep proof of transmission. Sell in the market where this type of collateral actually sells, and document why. Keep the marketing record: listings, outreach, days on market, bids received. Prepare the collateral where modest expense produces a materially better price. Avoid buying it yourself absent clear authority. Apply proceeds strictly according to the agreement and the statute. A deficiency claim backed by a clean file collects. One backed by a same-day auction and no notification frequently doesn’t.
Article 9 hands a secured party an extraordinary power: take property without a lawsuit, sell it without a court. The price of that power is procedural discipline. A debtor facing a deficiency isn’t asking for charity. They’re asking whether the party that used self-help did it the way the statute requires. That question gets answered with documents, and I intend to make the other side produce them.
