In a private sale, the only warranty is what the seller said

The dispute always arrives the same way. A few days after the handoff, a message: this wasn’t working properly, I want a refund. The seller says they disclosed it. The buyer says they did not.

Both sides go back through the chat log. And the chat log has the address and the meeting time, because everything about the item was discussed in person.

Nothing you agreed on in the parking lot exists anywhere.

Buying from a person is not buying from a business

This is the part most people find out afterwards.

The implied warranty of merchantability under UCC §2-314 — the automatic baseline promise that goods are fit for their ordinary purpose — arises only where the seller is a merchant with respect to goods of that kind.

The official commentary is explicit: a person making an isolated sale of goods is not a merchant within the meaning of the section, and so no warranty of merchantability applies. You cannot sue a neighbour because the used lawnmower from their garage sale failed the next day.

The reasoning is a policy choice. The warranty places a heavy burden on the seller to deliver quality, so the law limits it to professionals who can inspect goods and spread the cost of defects. Casual sellers, who have neither the specialised knowledge nor the quality control, are deliberately left out.

One caveat worth knowing. If the person is actually running a business — reselling the same category of item at volume — they may be a merchant regardless of how the listing looks. That changes the analysis entirely.

What is left is what was said

Private sales are not a lawless zone. Three things still apply.

Express warranties, UCC §2-313. These arise from affirmations of fact or promises made by a seller that become part of the basis of the bargain. Crucially, this is not limited to merchants. If a private seller states the battery holds a full charge, that statement can be a warranty.

Fitness for a particular purpose, UCC §2-315. Usually a merchant doctrine, but courts have noted it may apply to non-merchants where the circumstances justify it — where the seller knew the buyer’s purpose and the buyer relied on their judgment.

Fraud and misrepresentation. Separate from warranty entirely, and turning on whether the seller knowingly misstated something they knew.

All three run on the same fuel: what the seller actually said.

A real case, on Facebook Marketplace

In a 2023 New York decision, a buyer purchased a washing machine through a Facebook Marketplace listing and sued when it did not work as expected.

The court found the seller was not a merchant — she did not regularly deal in washing machines, nor hold herself out as having knowledge or skill peculiar to goods of that kind. She was, in the court’s words, more accurately described as a casual or inexperienced seller. No implied warranty of merchantability arose.

And on the express warranty question, the court found no evidence that the advertisement — the listing itself — created any express warranty.

The listing was not enough. Which means, in practice, that whatever was said at the handoff would have been the case.

The five minutes that decide it

Look at how these transactions actually run. The chat covers logistics. The item gets discussed in person.

“There’s a small dent on this side, you can see it there.” “Battery’s a bit worn but it holds fine for a day.” “No box, but the charger’s included.” “Go ahead and turn it on — tell me if anything seems off.”

Five minutes, cash changes hands, everyone leaves. Days later those five minutes are the entire case, and nothing recorded them.

The seller’s side of the same problem

It is tempting to read all of this as seller-favourable. It is not, quite.

Your statements can still bind you. No implied warranty does not mean no warranty. An express warranty under §2-313 needs no formal language and no merchant status — an affirmation of fact that the buyer relied on is enough.

Disclosure is your defence, and you have to show it. A seller who described the defect is in a strong position — if that can be established. Verbally, in a parking lot, it usually cannot.

Silence about a known defect is a different risk. Warranty and fraud are distinct claims, and a seller who knew about a problem and said nothing is exposed on the second one even where the first fails.

And accusations escalate. Sellers who decline refunds are commonly threatened with fraud reports. Fraud requires knowing misstatement, which is not the same as a disagreement over condition — but that determination is made by someone else, based on what can be shown.

The practical protection is identical on both sides: put the condition in writing in the chat before you meet. One message listing the flaws — as discussed: dent on the left side, battery around 80%, no original box — changes the character of any later dispute completely.

Keeping the part that happened in person

The chat is the reliable record, and using it more is the first answer.

What it cannot cover is the handoff itself, where the item gets examined and described in real time, and where neither side knows yet which sentence will be the one that matters.

TalkSafe covers that gap. You set a few words in advance and recording starts when one of them is heard. It starts with the screen locked — the phone stays in a pocket through the meetup.

The words do not have to be ones you say. Set what the other person is likely to say while describing the item — scratch, battery, works fine, condition, no box, tested — and the moment the item gets discussed is the moment recording begins.

It cuts the same way for both parties. For a buyer it supports nobody mentioned that. For a seller it supports I told you about that up front. Whoever was being straight, the record shows it.

Because the 30 seconds before the trigger are saved too, a description already underway is captured from its start.

A few notes

A notification stays visible while recording and cannot be switched off. This is for keeping a record of a conversation you are part of.

Recording law varies by state — most allow a participant to record; about a dozen require everyone’s consent. That matters for an in-person meetup with a stranger, so it is worth knowing your state’s rule. Covered separately.

The chat comes first. A recording fills what the chat cannot capture; it does not replace it. Anything important said in person is worth repeating in a message afterwards.

Small claims is the venue. Amounts usually fall within the limit, filing is cheap, and the decision turns on evidence rather than insistence.

Use platform payment protection for anything expensive. Cash in a parking lot leaves nothing to reverse.
