"They told me it was good, but..." Have you ever been frustrated by a second-hand purchase?

min-Joon, an office worker, bought a graphics card described as "top-notch" at a second-hand store to build his dream PC. Excitedly, he installed it, but the screen was cracked and the computer kept freezing. When he contacted the seller, the response was cold: "Second-hand transactions between individuals are non-refundable. didn't you know?"

many people resign themselves to the fact that refunds on person-to-person used transactionsare impossible. Should I give up my hard-earned money just because the seller says "no refund"? the answer is no.

in fact, the law is on your side. the biggest barrier isn't the law, it's the myth of the "can't" and the psychological barrier it creates. sellers capitalize on this myth, and buyers give up easily without doing their research. this article is the perfect guide to busting the myths of person-to-person trade-in refunds, giving you the legal basis, real-world examples, and a step-by-step action plan to get your money back. It's time to stop being a frustrated victim and start being a smart consumer who knows their rights.

1. the basics of second-hand refunds: the crucial difference between 'simple change of heart' and 'defective goods'

1.1 Why can't there be a "simple change of heart refund within 7 days" like online stores?

when we buy something from an online store, if we don't like it, we can easily get a refund within 7 days. this is thanks to the Act on Consumer Protection in Electronic Commerce (hereinafter referred to as the E-Commerce Act). this law applies to business-to-consumer transactions (B2C) between a registered 'mail-order business' and a consumer, and guarantees consumers a powerful right called the 'right of return'.

however, person-to-person second-hand transactionson carrot and stick, craigslist, and thrift stores are different. these are transactions between individuals and individuals (C2C), not businesses, and are therefore not covered by e-commerce law. instead, they're governed by the general principles of "civil law," which governs all contractual relationships between individuals. And civil law doesn't have a refund policy for simple change of heart. So if you don't like the color of something you bought second-hand, or you decide you don't need it anymore, you can't legally demand a refund from the seller.

1.2 How 'civil law' protects you, the legal foundation of person-to-person transactions

so, does that mean you don't have any legal protection in a person-to-person transaction? No. A person-to-person used transaction is still a promise, or "contract," between two parties. the seller has an obligation (a debt) to hand over the item as described, and the buyer has an obligation to pay.

what if the seller described and sold you a 'working laptop', but in reality sent you a broken product that wouldn't turn on? This would constitute a 'default' - the seller didn't fulfill his obligation. at this point, the buyer has the legal right to rescind the contract and demand a refund in a person-to-person used transaction.

2. demystifying 'liability for defects', the key to a refund

2.1 What is 'liability for defects'? The seller's hidden obligation

the strongest legal basis for a refund on a person-to-person used transactionis 'liability for defects' under civil law. this is the principle that a seller is liable for any defects in an item that the buyer didn't know about at the time of the transaction. In other words, a seller can't escape liability for defects that they didn't know about.

under liability for defects, the buyer can exercise the following rights

  1. rescind the contract (demand a refund): This is possible if the defect is so significant that it defeats the purpose of the contract. for example, if you buy a smartphone and it has a serious flaw in its calling capabilities, you can cancel the contract and demand a full refund.

  2. claiming damages (asking for the cost of repairs): You can keep using the item, but ask the seller for the damages (usually the cost of repairs) caused by the defect.

2.2 What qualifies as a 'defect'? (Focusing on real-life disputes)

the scope of "defect" is broader than you might think. Let's take a look at some real-life dispute resolution cases to see what can be considered a defect and result in a refund for a person-to-person used transaction.

  • case 1: Functional def ects A product is clearly defective if it fails to perform its core function as advertised, such as Minjun's graphics card in the first case. other examples include electronics that claim to be "fully functional" but are actually broken, and washing machines that claim to be "leak-free" but leak water.

  • example 2: Breach of disclosure: You receive a camera that the seller describes as having "some living gas," but upon inspection, you find large mold inside the lens that affects the quality of your shots. this is a "breach of duty of disclosure," where the seller failed to disclose important information, which is a defect. the greater the gap between the seller's description and the actual condition, the higher the likelihood of a refund.

  • example 3: Counterfeits and rights defects If a luxury bag that you bought thinking it was authentic turns out to be a counterfeit, then that's a valid reason for a refund. additionally, if you were sold something that you had no right to dispose of, such as a stolen item (stolen goods) or a lost item (lost property), then this is also a "defect of right" that voids the contract and entitles you to a refund.

2.3 The truth behind the "No Return" (NR) phrase: void in the eyes of the law?

it's not uncommon to see the phrase "no refunds under any circumstances" in a used item listing. while this phrase is valid for simple change of heart, it's very likely to lose legal standing when a major defect is discovered that the seller didn't disclose.

the law looks more to the substance of the contract than to any special terms between the parties, meaning that a promise to sell a "product in good working order" trumps a "no refunds" add-on. even the government's 'Guidelines for the Settlement of Disputes in Transactions between Persons' states that you can cancel the contract if you find a material defect, even if the seller has notified you of the non-refundability.

2.4 Golden time to exercise rights: What does 'six months from the date of knowledge of the defect' mean?

the Civil Code stipulates that the buyer must claim liability for defects 'within six months from the date of discovery of the defect'. this six-month period may seem generous on its face, but there is an important pitfall.

as time passes, it becomes exponentially more difficult to prove whether the defect 'existed from the time of the transaction' or 'was caused by the buyer's use'. legal battles are all about the battle of the evidence. if you bring up the issue months after the purchase, the seller will counter with "you broke it with use" and it's very hard to overturn that.

so, legal timeframes aside, the surest way to increase your chances of getting a refund on a person-to-person used transaction is to inspect the item thoroughly and raise any issues within a week of receiving it, preferably sooner. even in dispute resolution cases, we've seen buyers fare much better if they raise issues within 24 hours or three days of receipt.

3. a 3-step hands-on roadmap to dispute resolution

if a seller comes out swinging with a refund refusal, you should take a methodical approach rather than reacting emotionally.

3.1 Step 1 - Record everything the art of evidence

once a dispute begins, all claims must be backed up with evidence. make sure you have the following list

  • capture the sale post: Make sure you capture the entire original post, including the seller's description, photos, price, etc.

  • save conversations: Save all conversations you've had with the seller, including platform chats, texts, and Kakaotalk.

  • proof of transfer: A bank transfer confirmation of the money you sent to the seller is a must.

  • take an 'unboxing video': Filming the entire process of opening the package is the strongest evidence that the item was defective from the time it was delivered.

  • capture thedefective condition: Take detailed photos and videos from multiple angles that clearly show the problem.

  • obtain objective evidence: If possible, get a statement of defect or repair estimate from an authorized service center or expert to multiply your evidence.

3.2 Step 2 - Send an ultimatum: How to write and send a proof of claim

"Proof of delivery" is not a lawsuit per se, but a way to publicly prove "who sent what, when, and to whom" through the post office. while there's no legal enforcement in itself, a certificate of service sends a strong psychological signal to the seller that "I'm prepared to take legal action," which may encourage them to resolve the issue before litigation. it also serves as an important piece of evidence in a future lawsuit.

[Sample proof of content]

  • subject: Request for rescission and refund due to defective used goods transaction

  • from: (name), (address)

  • to: (seller's name), (address)

  • content:

    1. on OOOO, OOOO, I purchased [name of item] from you through [platform name] for [amount].

    2. you informed me that the goods were in 'good working order', but upon receipt, I found [specific defect].

    3. this is a clear breach of contract that constitutes 'defect liability' under civil law.

    4. therefore, I am hereby requesting the cancellation of the contract and a full refund of the purchase price in the amount of [amount].

    5. please refund the full purchase price of [amount] within 7 days of receipt of this proof of content to the following account: (Bank: OO Bank, Account No.: OOO-OOO-OOOOOO, Depositor: OOO)

    6. if the refund is not made within the deadline, we will file a civil lawsuit, including small claims court, without further notice.

you can prepare three identical copies of the completed proof of content and send them to the post office. one copy for the seller, one copy for the post office, and one copy for yourself.

3.3 Step 3 - Last resort: 'Going it alone' without a lawyer (small claims court)

if the seller doesn't respond to your proof of content, you should consider legal action as a last resort. if the amount of your claim is 30 million won or less, you can use the 'Small Claims Court' system, which allows you to proceed without a lawyer.

[Summary of Small Claims Court Procedures]

  1. filing acomplaint: You can easily file a complaint online through the 'Korea Court E-Litigation' website.

  2. decision to recommend implementation: After the court reviews the complaint, if it finds reason, it will first issue a 'decision to recommend implementation' to pay the seller (defendant). if the seller doesn't object within two weeks, then this decision has the same effect as a final judgment.

  3. arraignment date: If the seller contests the judgment, a trial date (arraignment date) is set. small claims cases are usually heard in a single trial.

  4. judgment: The judge will review the arguments and evidence from both sides and make a judgment.

the cost of litigation, including stamp duty and service fees, is low, in the tens of thousands of won, and the duration varies depending on the case, but can be as short as two to three months or as long as six to eight months or more.

4. how to deal with 'used transaction fraud' beyond simple defects

4.1 How to determine if your case is a "scam

having a defect in an item and being scammed outright are treated differently under the law. while a simple defect dispute is a civil matter, fraud is a criminal offense punishable by criminal penalties. in order to commit secondhand fraud, the seller must have had the "intent to deceive the other party (fraud) and obtain property (intent to defraud) from the outset.

[obvious types of used car fraud]

  • brick fraud: When you send money and instead of goods, you get bricks or trash.

  • payment and disappearance: The scammer takes the money but doesn't send the item and disappears without contact.

  • third-party fraud: A scammer interposes themselves between the seller and the buyer, tricking the buyer into depositing money into their account and the seller into sending the wrong item.

  • secure payment phishing: A scam that sends a link to a fake secure payment page that looks very similar to the real site and tries to get you to pay.

4.2 What to do if you're a victim of secondhand scams

if you've been scammed, you should act immediately.

  1. gather evidence: Capture and organize all evidence, including seller information (username, name, contact information, account number), posts, conversations, and transfer history.

  2. report to the police: File a formal report with the Cyber Investigation Team (not the nearest precinct) by visiting the police station's complaint room or through the Electronic Crime Reporting System (ECRM).

  3. criminal and civil proceedings are separate: Here's a very important point. police reports and criminal proceedings are meant to 'punish' the fraudster. to 'get your money back' you need to go through a separate 'civil' process, such as sending a proof of service, small claims court, etc. as described above. it is important to remember this 'two-track' strategy: the police will not take your money.

5. prevention is the best medicine: A safe trading manual for everyone

the only thing better than dealing with disputes and scams after the fact is preventing them in the first place.

5.1 Fraud prevention checklist for buyers

  • before the transaction: Check the seller's past transactions, posts, and date of joining the platform. Be sure to look up the seller's contact information and account number on scam tip-off sites like The Cheat Sheet. be suspicious of listings that are abnormally low below market value.

  • during the transaction: Use the platform's built-in secure payment (escrow) service whenever possible. never click on a payment link from a seller that directs you to an external messenger like KakaoTalk. for in-person transactions, meet in a public place with lots of people and check the item carefully before paying, and for courier transactions, ask the seller to take a photo of the item with a note saying "today's date and your nickname" to confirm that you actually own the item.

5.2 Dispute prevention guide for sellers

  • write detailed and honest listings: describe the condition of your item in as much detail as possible, and don't hide any flaws, such as scratches, dirt, or defects, but clearly disclose them with photos.

  • keep all communication within the platform: use the in-platform chat feature to communicate whenever possible so that there is an official record in case of a dispute.

  • video the packing process: If you're selling an expensive item, videoing the process of safely packing a fully functional product can help protect you from false claims from buyers.

6. refunds for person-to-person used transactions, frequently asked questions (FAQs)

Q1: I bought an item in person and checked it out in person, but when I got home I realized it was defective. Can I get a refund? A: Yes, you may be able to. if it's a "hidden defect" that's hard to see in person (e.g., an internal defect in an electronic device that only shows up after use), then you may be liable for the defect unless the seller disclosed it to you. government dispute resolution standards also recognize this. however, cosmetic blemishes that were easily visible at the time of purchase may be considered buyer negligence and may be difficult to refund.

Q2: How much does it cost to file a small claims court case and how long does it usually take? A: The cost varies depending on the amount of the claim, but for small claims cases in the hundreds of thousands of won, it can be as low as a few tens of thousands of won, including stamp duty and service of process. the timeframe depends on the court and the complexity of the case, but can be as short as two to three months if the defendant's address is clear and the case is uncontested, or six to eight months or more if there are address corrections or lengthy pleadings.

Q3: After the transaction, the seller deleted the account and disappeared. What should I do? A: This is most likely a classic fraud scheme. You should immediately report it to the police department's cyber investigation team with all the evidence you have (transcripts, account numbers, names, etc.). the police can use the account information to track down the suspect.

Q4: I only want the cost of the repair, do I have to give a refund? A: No, you can file a 'claim for damages' and ask for the repair costs only. this is one of the buyer's legitimate rights under the liability for defects. you can either settle with the seller and get the repair costs, or you can go to court and ask for the value of the repair costs instead of a refund.

Q5: Will the platform itself, such as Carrot Market or Lightning Market, resolve disputes? A: Platforms do not directly intervene legally or force refunds, but they may have dispute resolution processes. For example, Carrot Market may offer a mutually agreeable resolution to disputes, and may impose sanctions such as bans for policy violations. we recommend contacting the platform's customer support in the event of a dispute first.
