Challenging the personal guarantee behind an MCAfive grounds, examined for 2026

Challenging an MCA personal guarantee: what it covers, what defeats it, and what to pull first

A personal guarantee enforces nothing by itself. The funder talks about it as a switch, signed once and thrown at the first missed remittance, and the collections desk recites it over the phone as though recitation were process. That posture is what you are expected to accept.

It is an agreement. Agreements have terms, limits, prerequisites and defenses, and nobody working a commission on your file will point out any of them. Five grounds decide, in practice, whether the paper you signed carries the weight the funder assigns it.

Ground one: read what the guarantee actually guarantees

Start here, because this ground resolves more disputes than the other four combined and it takes ten minutes.

Merchant cash advance guarantees are frequently drafted as performance guarantees rather than guarantees of payment. The distinction is structural to the product. The funder claims it bought receivables and took the risk of the business underperforming, so the guarantee cannot cover the ordinary event of receipts falling short. Instead it triggers on specified misconduct: blocking the ACH, diverting receipts to an undisclosed account, selling the business without consent, filing for bankruptcy, misrepresenting revenue in the application.

So the operative question is not whether you signed one. It is which list of triggers appears in your document, and whether the funder can point to any of them. A business that simply earned less this quarter has not triggered a performance guarantee, and collections calls asserting otherwise are asserting a term the paper does not contain.

Read the guarantee's own heading, then the trigger list, then the definitions. If the funder is enforcing on a trigger the document does not name, the demand is wrong on its face.

Ground two: a guarantee borrows all of its strength from the advance

A guarantee secures an obligation. Weaken the obligation and you weaken the guarantee by the same amount, because there is no independent debt for it to attach to.

That puts the classification question directly in play. If the arrangement functions as a loan rather than a purchase of future receivables, the entire contract is exposed to defenses that a purchase of receivables would not face, and the guarantee falls with it. Courts examining these agreements look past the recitals on page one to what the parties actually did: whether the reconciliation right was real or ornamental, whether the funder bore any genuine risk of loss, whether the term was truly indefinite or effectively fixed.

The label on the document does not control. Conduct does. And a funder facing a serious recharacterization argument is a funder deciding whether it wants a ruling that its standard form is a sham, which is a very different negotiation from the one its collections desk opened with.

Ground three: capacity, consideration and the signature block

Pull the signature pages of every advance and look at them side by side. This is where high-volume paperwork breaks down.

Check whether you signed once or twice. Many agreements require a separate signature in an individual capacity for the guarantee to bind you personally, distinct from the signature binding the company. A single signature under a title, with the entity named above it, raises a real question about whether a personal obligation was created at all.

Check who else signed. A minority owner, a spouse with no ownership interest, a manager added to the paperwork because the funder wanted a second name: each of those raises questions of authority, consideration and, on occasion, whether the signature is genuine.

Then check the guarantees attached to later advances. On a stacked file the second and third guarantees are often broader than the first, and owners sign them believing the terms carried over unchanged. They rarely do.

Ground four: the instrument the funder plans to enforce with

Guarantees are usually enforced through a confession of judgment, and that instrument has to be correct on its face because nobody appears to contest it before entry.

Volume is where the process betrays itself. These are filed by the hundred, generated from templates by staff who will never read the underlying agreement, and the output shows it. Notarizations missing. The wrong county named. The amount confessed padded with fees no contract authorized. A guarantor named in the judgment who never signed a guarantee at all. Any one of those defects supports a motion to vacate.

The rules governing what a confession affidavit must contain and how quickly you can move against one vary by state, and the clock generally runs from entry rather than from the day you find out. Confirm the local requirements before doing anything else.

Vacating the judgment does not erase the debt. It returns the funder to ordinary litigation, with service, an answer and every defense listed on this page available to you. That is the position the confession was drafted to avoid, which is exactly why it is worth taking away.

Ground five: the funder breached first

A guarantor can raise the defenses belonging to the underlying obligation, and the most common one on an MCA file is the funder's failure to reconcile.

The agreement promises an adjustment when receipts decline. Submit a written request with revenue documentation and see what happens. Many funders ignore it, refuse it without explanation, or bury it under procedural conditions invented after the fact. That failure is a breach of the funder's own contract, and it also undermines the story that the deal was a purchase of receivables rather than a fixed loan.

Send the request whatever you plan to do next. Keep proof of delivery. An unanswered reconciliation request sitting in the file changes both the legal analysis and the settlement number the funder will accept.

What to pull before the first conversation

• Every advance agreement with all exhibits and addenda, not just the first page and the signature page.
• The guarantee itself, including its heading, its trigger list and its definitions section.
• Every signature page across every advance, so capacity can be compared side by side.
• Any confession of judgment you signed, plus the affidavit if you have it.
• Three months of bank statements showing the debits, and any reconciliation request you sent along with proof of delivery.
• All default notices, demand letters and UCC filings against the business.

A first conversation about the guarantee costs nothing and commits you to nothing. What it produces is a straight answer about which of these five grounds your paperwork actually supports.
