How to claim against an online marketplace seller through small claims court

Steps to take when marketplace buyer protection fails and you need to recover money through the courts.

Exhaust the platform dispute process

Open a formal dispute via the marketplace (eBay Money Back Guarantee, Amazon A-to-z, Vinted buyer protection). Document every step and screenshot the outcome.

For traders, you sue the business. For private sellers, you sue the individual. A "private" listing from a seller with 500 transactions may still legally be a trader.

Write to the seller formally

Email the seller stating the item was not as described or not delivered, the amount you want refunded, and a 14-day deadline before you issue a court claim.

Send a Letter Before Action

If they do not respond, send a formal Letter Before Action. For traders, give 30 days; for private sellers, give 14 days.

File via Money Claim Online

Issue your claim via MCOL. Include the item price, any return postage costs, and the court fee. Attach screenshots of the listing, dispute, and correspondence.

Get your money back through the payment first

Before a court claim, work through how you paid. These routes are free, they are faster than issuing, and they do not require you to identify or locate the seller.

Use these in order. A court will reasonably ask why you issued a claim when a free remedy sat unused, and a refused section 75 claim is itself useful evidence.

Finding out who you are actually suing

A claim form needs a name and an address for service. A username is neither. This is the single most common reason marketplace claims stall, and it is worth ten minutes before you pay a court fee.

Screenshot the listing, the seller’s details and your messages now. Listings are routinely deleted once a dispute starts, and a screenshot taken today is worth more than a description written in three months.

Platform protections

Most marketplace disputes resolve through the platform’s own buyer-protection scheme — faster and free. Use platform first, court as fallback.

Your legal rights — trader vs private seller

Seller typeYour protections
Trader (business seller)Full Consumer Rights Act 2015 protections — satisfactory quality, fit for purpose, as described. Plus 14-day right to cancel under Consumer Contracts Regulations 2013 for online purchases.
Private seller"Buyer beware" applies. The seller must not misrepresent the goods, but otherwise no implied quality terms. Your only claim is misrepresentation or breach of an express promise.

When to use small claims

Always exhaust platform protection first — courts expect you to mitigate by using free remedies before bringing a claim.
