Merchant Cash Advance Company Sent a Lien Notice to Your Processor? What a 406 Notice Does to Your Card Money

It usually starts quietly. Your card settlements — the batches that land in your account every day or two — stop arriving, or arrive short. Then a customer calls: they got a letter saying your receivables were assigned and they should pay somebody else from now on. Nobody sued you. No judge signed anything. No sheriff showed up. And yet your money is being rerouted by a letter.

That letter is a UCC lien notice of assignment — in the industry, a "406 notice," because it leans on § 9-406 of the Uniform Commercial Code, which South Carolina adopted as S.C. Code § 36-9-406. It is the merchant cash advance industry's favorite pressure tool, and it works not because a court blessed it, but because everyone who receives one is afraid to ignore it. This post explains what the notice actually does, why your processor obeyed it, where these notices are defective, and how South Carolina law — including a 10-day release rule most owners never hear about — unwinds them.

Your Card Sales Stopped Arriving — But Nobody Sued You and No Court Was Involved

The first thing to understand is that the freeze you are experiencing is not court enforcement. A 406 notice is a private letter. The factoring industry's own trade magazine, describing how merchant cash advance providers operate, puts it plainly: at the first sign of financial struggle, MCA providers send letters to the borrower's client base demanding that all money owed to the borrower be redirected to the provider — and those letters are not issued by a court or even, in the trade account, by a lawyer.

Yet the money stops, for two different reasons depending on who got the letter. Customers who receive one usually do one of two things: pay the funder, or freeze and pay nobody while they figure out who is lying. Processors who receive one hold settlements rather than risk releasing money to the wrong claimant. Either way, the business's cash flow is cut off at the exact moment it can least afford it — which is not a side effect of the tactic. It is the tactic. A business that cannot touch its card money settles fast, on the funder's terms.

If this is happening alongside a blanket filing you never agreed to, the notice is only the second half of the play; the first half is the filing itself, which we take apart in our post on removing an MCA company's UCC lien.

What Is a UCC Lien Notice of Assignment, and Why Did Your Processor Obey It?

Section 36-9-406 is the Article 9 machinery for assigning accounts — money other people owe your business. In plain terms, the statute works like this: once an account debtor — anyone who owes the business money on an account, which includes your customers and, for card receivables, sits behind your processor's settlement flow — receives an authenticated notification that the amount due has been assigned and is to be paid to the assignee, that account debtor can only discharge its obligation by paying the assignee.

Read the consequence carefully, because it explains everything that follows. If your customer gets a facially valid notice and pays you anyway, the payment does not count. The customer still owes the money — to the funder. Your processor is in the same position at scale: it settles card batches for thousands of merchants, and a notice claiming those settlements belong to a funder puts every dollar it releases to you at risk of having to be paid a second time, to the funder.

So the processor obeyed the letter for the same reason your customers froze: the statute makes ignoring a valid notice the expensive option. The notice weaponizes the recipient's risk, not yours. Nobody at the processor investigated whether the funder's claim was real, whether you were actually in default, or whether the filing behind the notice was authorized. That investigation is not their job — and undoing the notice is yours.

The Pay-Twice Trap: Why Customers and Processors Freeze Instead of Paying You

Lawyers who write about § 9-406 call the recipient's dilemma the pay-twice trap, and it is worth seeing from the recipient's chair. Your best customer gets a letter on funder letterhead saying your receivables were assigned, payment must go to the funder, and payment to you will not discharge the debt. The customer does not know you. The customer does not know the funder. What the customer knows is that paying the wrong party means paying twice.

Faced with that, rational recipients do one of three things: pay the funder, hold the money and wait, or call you in a panic. The first costs you the receivable. The second costs you the cash flow. The third costs you the relationship — your customer is now involved in your financing problems, wondering what else is wrong, and quietly shopping for a vendor whose invoices do not come with legal letters attached.

That customer-relations damage is part of why the notice tactic is so effective and, when the underlying claim is bogus, so abusive. The funder spends a stamp and buys pressure on every front at once: your processor, your customers, and your reputation. Which is why the response cannot be a phone call to the funder's collections floor. The response has to unwind the notice at every recipient it reached — and South Carolina law has a specific tool for exactly that, covered below.

A 406 Notice Is Not a Court Order — Here's What It Actually Is

Because recipients treat the notice like a court order, it is worth being precise about what it is and is not.

It is not a judgment. No court has found you owe anything. It is not a levy or a garnishment; no sheriff or clerk is involved, and it does not carry a court's authority. It is not even, in the end, proof of an assignment — it is a claim of assignment: the funder asserting that your receivables were assigned to it under a security agreement and a UCC filing, and that a default or other trigger entitles it to collect directly.

The notice's legal force comes entirely from the statute's discharge rule: a recipient who gets an effective notification protects itself by paying the assignee. Everything turns on the word "effective." A notification that does not meet the statute's requirements, sent by a party with no right to send it, over receivables it has no interest in, is not a court order at all — it is a letter with a statute quoted on it. And the difference matters, because a recipient who learns the notice is defective can safely go back to paying you.

When the Notice Is Defective: It Has to Identify the Rights Assigned, and Proof Can Be Demanded

Article 9 does not let just any letter redirect your money. Two built-in checks protect the business and its account debtors, and both are underused because nobody tells recipients they exist.

First, identification. A notification is ineffective if it does not reasonably identify the rights that were assigned. A blanket letter claiming "all receivables" from a business, sent to customers whose invoices the funder cannot connect to any agreement, is testable on exactly this ground — the recipient is entitled to know what, precisely, was assigned, and a notice that cannot say is a notice that does not work.

Second, proof. The statute lets an account debtor demand reasonable proof that the assignment was actually made — the security agreement, the assignment language, the paper. Until reasonable proof arrives, the account debtor may keep paying the business as if the notice never came. That single rule deflates most notice campaigns: the funder that blasted letters to your entire customer list now has to produce its claimed agreement, recipient by recipient, or watch the recipients lawfully go back to paying you.

In practice, a lawyer's letter to the key recipients — processor first, major customers second — enclosing the demand for proof and explaining the discharge rule cuts both ways: it tells recipients the safe course is to hold payment to the funder until proof shows up, and it puts the funder on notice that its paper is being examined. Funders who actually hold a signed agreement and a genuine default can usually produce proof. Funders running a pressure play usually cannot — and the silence becomes evidence.

No Default, No Authorization, No Right to Redirect: Attacking the Paper Behind the Notice

Behind every 406 notice sit three predicates, and the notice stands only if all three hold: a real agreement assigning the receivables, an authorized UCC filing perfecting the claim, and — for the secured party's own collection rights under § 36-9-607, which lets a secured party notify account debtors to pay it directly — either agreement language allowing it or an actual default. The statute also requires a secured party that undertakes collection to proceed in a commercially reasonable manner. Blanket notices blasted to every customer a business has, on a disputed or manufactured default, are the fact pattern that requirement exists for.

Attack each predicate. If you never signed the MCA agreement — or the "agreement" came from a broker submission you never approved — there is no assignment and the notice is void at the root; the filing behind it is unauthorized under § 36-9-509 and ineffective under § 36-9-510(a). If the debt was paid or settled, the right to redirect died with it. If there is no default — payments current, reconciliation refused, the "default" invented from a bounced debit the funder itself caused — the collection right was never triggered.

The cleanup machinery then runs on the same track as every wrongful-filing case in this series: an authenticated demand under § 36-9-513(c) starting the 20-day termination clock, a debtor-filed UCC-3 under § 36-9-509(d)(2) when the clock blows, and a § 36-9-518 information statement invoking § 36-9-516(b)(8) so the Secretary of State can make the funder produce the agreement it claims. And where a secured party is enforcing in a way Chapter 9 does not allow, § 36-9-625(a) lets a court order or restrain the enforcement itself — the tool for notices that need to stop now, not in 20 days.

The documented end of this road is what happened to the Yellowstone Capital network: in January 2025, a New York Attorney General judgment and settlement of more than $1 billion cancelled $534 million in merchant debts, required the network to terminate its liens against merchants, and barred it from the MCA business. Yellowstone resolved the case without admitting the allegations. The Richmond Capital group met the same wall in court: a 2023 ruling rescinded its loan documents and ordered all related liens terminated. Adjudicated outcomes against the model — a reminder that the paper behind a notice campaign sometimes cannot survive being read by a judge.

South Carolina's 10-Day Release Rule: Making Them Un-Send the Notice to Everyone They Sent It To

Here is the tool almost nobody in this fight knows exists. South Carolina Code § 36-9-209(b) provides that within ten days after receiving the debtor's authenticated demand, a secured party must send an authenticated record releasing an account debtor from further obligation to the secured party — to every account debtor that received a § 36-9-406 assignment notification.

Translate that into the freeze you are living in. The funder notified your processor and your customers to pay it instead of you. Once the obligation is satisfied — or the claim collapses because there never was an authorized filing or a real default — you do not have to chase each recipient yourself and beg them to believe the notice is dead. You demand, in an authenticated writing, and the statute puts the duty on the secured party to send the releasing record to everyone it notified. Ten days. Their stamp, their letterhead, their retraction.

The demand should list every recipient you know received the notice — processor, customers, factors, brokers — and demand the releasing record go to each. Send it certified mail, return receipt requested, and keep the proof. A funder that refuses has now violated a second, specific statutory duty, on top of whatever was wrong with the notice in the first place, and § 36-9-625 makes noncompliance expensive, as the next sections show.

Pair the release demand with the termination demand from the last section and the two clocks run together: 20 days to terminate the filing, 10 days to retract the notices. When both blow, you hold a clean record of a funder that would not undo its own paper — which is exactly the record a court wants to see.

Split Settlements: When the Funder Was Inside Your Card Batches From Day One

One variant needs separating out, because it is not a notice problem at all. In split-processing MCA structures, the interception is built into the deal from the first day: your processor is instructed to remit an agreed percentage of every card batch directly to the funder before you see a dollar. No letter arrives later; the split is the plumbing.

If you signed that structure, the fight is not about a defective notice — it is about the agreement: whether the percentage being taken matches the contract, whether the funder refused the reconciliation the contract promised when your sales dropped, whether the "default" it declared is real, and whether what was sold as a purchase of receivables was actually a loan wearing a costume, which is the argument that has undone MCA contracts in court. Those are document fights, and they start with the agreement, the payment history, and the processor's split instructions — all three, read together.

But watch for the moment a split deal goes bad, because that is when the 406 notices appear: the funder, no longer content with its percentage, notifies your customers and your bank directly. The day the letters go beyond the agreed split is the day the notice rules above start applying. Keep every one of them. The envelope, the date, and the recipient list are the map of what has to be unwound.

What to Tell Your Customers When a Stranger Demands They Pay It Instead

Your customers are not your lawyers, and the goal with each of them is simple: keep the relationship, keep the payments lawful, and do not make promises you cannot keep. A short, written, factual communication does the work:

• Tell them the notice is disputed and that the sender has been demanded to produce proof of the assignment it claims — and that until reasonable proof is provided, the statute allows them to keep paying you in the ordinary course.
• Tell them a release demand under South Carolina law has been made (or is being made), and that they will receive the releasing record from the sender when it issues — or a copy of the filed termination from you.
• Give them one contact — you, or your lawyer — for questions, and ask them to send you any further letters they receive instead of acting on them.
• Do not tell them the notice is "fraud" or "illegal" as a conclusion; tell them it is disputed, unsupported so far, and being unwound through the statutory process. Precision protects you if the paper turns out messier than expected.

Then do the same with your processor's risk or legal department, in writing: dispute notice, proof demanded, releases demanded, termination filed or coming. Processors unwind holds on paper. Give them paper.

The Damages Side: § 36-9-625, SCUTPA, and Interference With Your Customers

A notice campaign aimed at your customers and your processor is not just a collections tactic when the claim behind it is bad — it is a damages case with the recipients as witnesses. Section 36-9-625(b) makes a noncomplying secured party liable for the loss its failure caused, expressly including loss from your inability to obtain alternative financing and its increased cost. The settlements that stopped, the customers who quietly left, the emergency money you borrowed at bad rates while your own revenue sat redirected: that is the ledger, and every recipient who froze your money documents an entry in it. Section 36-9-625(e) adds the flat $500 penalties for the unauthorized filing and the refused termination.

Layer on the South Carolina Unfair Trade Practices Act where the pattern supports it — notices sent to customers the funder knew were outside its collateral, a "default" manufactured to trigger collection rights, pressure designed to force a settlement rather than collect a debt. SCUTPA provides treble damages for willful or knowing violations and attorney's fees, under the same statute we use in consumer fraud cases. And a notice sent to a customer under contract with you, intended to divert payments the sender had no right to, is the shape of a tortious interference claim. We lay out the full damages playbook in our post on suing over an unauthorized UCC filing. Which of these claims your facts support depends on the paper — the agreement or lack of one, the notice, the recipient list, and the money trail — which is why the first step is always getting the documents read.

MCA Lien Notice Lawyer in South Carolina: What to Do Today

If a 406 notice has gone out with your name on it, do these things first:

• Save every notice. The letter, the envelope, the date received, and who received it — your processor, each customer, your bank. The recipient list is the unwind list.
• Do not tell recipients to just ignore it. Ignoring a notice is how a customer ends up paying twice. The statute gives recipients a safe path — demand proof, hold position — and your communications should walk them down it in writing.
• Demand proof of assignment — through counsel, in writing, to the funder, and start the § 36-9-209(b) ten-day release clock and the § 36-9-513(c) twenty-day termination clock with authenticated demands.
• Move everything to writing. Recorded calls with the funder's floor are where "agreements" get manufactured. Paper is where they get tested.
• Keep selling. Every invoice your customers pay you in the ordinary course, with the proof demand pending, is cash flow the tactic was designed to stop.
