Buying from a person is not the same as buying from a business

There is a short answer about private sales and consumer protection and a useful one, and they are not the same. What follows is the useful one.

Who consumer law is usually aimed at

The protections most people think of when buying goods are typically framed as obligations on a business selling to a consumer. A private individual selling a possession is generally not a business and does not carry the same obligations.

That difference is not a loophole; it reflects the fact that a private seller is not trading and has no ongoing operation. The consequence is that a used item bought privately usually comes with far less recourse than the same item from a shop. How far this goes, and what residual protections exist, differs considerably between countries and legal traditions.

What usually still applies privately

In many systems a private seller is still expected not to misdescribe what they are selling. An item that is materially different from its description can therefore remain a problem for the seller even privately. What generally does not apply is any expectation about quality, durability or fitness beyond what was actually stated.

Run the arithmetic and the practical effect is that buying privately puts the burden of inspection squarely on the buyer. That is why inspecting carefully in person matters far more in a private sale than in a shop.

Traders selling as private individuals

Somebody who sells regularly and for profit may be a trader in law even where the listing looks personal. Where that turns out to be the case, consumer protections may apply regardless of how the listing was presented.

Signs include high volumes, the same item listed repeatedly, unopened goods, business-style descriptions and obvious bulk stock. Establishing status is not something a buyer can do reliably, and it usually only becomes relevant during a dispute. Rules on how sellers must identify themselves vary and have been tightened in a number of places recently.

Marketplace protections are a separate layer

Many platforms operate their own buyer protection schemes, which are commercial policies rather than legal rights. Those schemes typically require the transaction to have happened through the platform and its payment system. Completing a sale outside the platform, including paying in cash on collection, generally removes that protection entirely.

At the till, time limits and evidence requirements apply, and they are usually short compared with any legal route.

Reading a platform's scheme before a large private purchase is more useful than reading it afterwards.

Reducing risk before you hand over money

Inspect the item working, in person, and test the functions you actually care about rather than accepting a demonstration. Ask direct questions in writing through the platform, because answers become part of the description you can rely on. Photograph the item at collection and keep every message, since a record is the only evidence a private sale produces.

Across a sale weekend, consider the payment route deliberately rather than by habit, because recourse differs enormously between methods and between jurisdictions. For anything expensive, the cost of buying from a business is frequently less than the risk of buying privately.

Prices, promotions and terms move constantly, so check the current number rather than this one.

Selling privately without creating problems

Describe faults plainly and photograph them, because an accurate description is your main protection as a seller. Avoid describing an item as working or perfect unless you have actually verified the claim recently. Keep a copy of the listing and the messages, since a disagreement will turn on what was said before the sale.

Run the arithmetic and provide any documentation you still have, since it reduces the buyer's uncertainty and makes the sale considerably easier. Selling honestly is not only decent but is also the position that holds up if anybody questions the sale afterwards.

The takeaway

Inspect harder when the seller is a person, because the protections you are used to were written with a business in mind.

A discount is a claim about a price you were never asked to pay.
