Ripped off on Facebook
Marketplace — can you sue?

By Jonathan Kleiman, Barrister & Solicitor · Published June 2026

A version of this question lands in my inbox almost every week. Someone bought a phone, a couch, a set of golf clubs, or a used car off Facebook Marketplace, and the deal went sideways. The item never showed up, or it arrived broken, or it was nothing like the listing, or the seller took a deposit and ghosted. The question is always the same: "Can I sue them?"

The short answer is yes — usually. A Marketplace deal is a real transaction with real legal consequences, and Ontario\'s Small Claims Court handles disputes like this up to $50,000. But there are two big catches that most people do not see coming. The first is a legal one: for private, person-to-person sales, the law leans heavily toward "buyer beware," which limits what you can complain about. The second is purely practical, and it sinks more of these cases than anything else — you often have no idea who the seller actually is.

Below I will walk through when you genuinely have a claim, where buyer-beware helps you and where it does not, the situations I see most often, and the unglamorous detective work that decides whether a lawsuit is even possible. None of this is legal advice for your specific situation — every case turns on its facts — but after years of these disputes in Ontario, this is what I tell people to think about before they spend a dollar on court.

Can you actually sue over a Facebook Marketplace deal?

Yes, you can. There is nothing special about Facebook Marketplace that puts a deal beyond the reach of the courts. The platform is just where the two of you met and struck a bargain. Once money changed hands for goods, you have a contract, and a contract that goes wrong is exactly what Small Claims Court exists to sort out — for any amount up to the $50,000 limit.

When I look at one of these disputes, I am usually sorting it into one of three legal buckets:

• Breach of contract. The seller did not deliver what they agreed to. The item never arrived, or it was not as described, or the seller failed to hand over what you paid for. If you want the full picture of how this works, I break it down in what counts as breach of contract in Ontario.
• Misrepresentation or fraud. The seller lied about the item — said it worked when it did not, hid a known defect, or sold you something that simply was not what they claimed. Fraud is the most serious version, and it is always actionable.
• Non-payment. This one runs the other direction. If you were the seller, handed over the item, and the buyer never paid (or reversed the e-transfer), you can sue them for the price.

So the "can I sue" question almost always answers itself: if one of those three things happened, you have grounds. The harder questions — the ones that actually decide whether you should file — come next. For a broader sense of what does and does not belong in this court, I wrote a whole piece on whether you can sue anyone for anything in Small Claims Court.

Does it matter that the deal happened on a platform?

Not really. People sometimes assume Facebook is somehow a party to the deal, or that the platform owes them something when a sale goes bad. It does not. Facebook is the bulletin board, not the merchant. Your dispute is with the human being on the other end of the chat, and your rights and obligations are the same as if you had met them at a garage sale or through a classified ad. The platform name on the listing changes nothing about the law.

From my experience

From my experience, the cases that work and the cases that fizzle out usually split along one line, and it is not how strong the legal claim is — it is whether the person on the other side can be found. I have had clients with airtight stories of being lied to, screenshots and all, who simply could not tell me the seller\'s last name. And I have had clients with messier facts who knew exactly who they dealt with, had the e-transfer trail, and met them at their house. The second group has a case. The first group, sadly, often does not.

The other pattern I see constantly is people learning the buyer-beware lesson the hard way. Someone buys a used appliance from a private seller, it dies a week later, and they are furious — they want to sue for a refund. But the seller was an ordinary person clearing out their basement, not a business, and they never claimed the thing was perfect. When the item simply turned out to be worn out, and nobody lied, there is often not much of a claim. It feels unfair, but private used-goods sales come with that risk baked in, and I would rather tell someone that early than after they have paid a filing fee.

The version that does have legs is when the seller crossed a line — they told you the laptop battery was new when it was shot, they swore the bike had never been stolen, they took your deposit and disappeared. A lie or a no-show is a different animal from disappointment, and that is the distinction I am always listening for when someone tells me their story.

What the law generally says

This is the part people most often get wrong, so it is worth slowing down. Whether you have a claim against a private seller depends heavily on what went wrong, because Ontario law treats private sellers very differently from businesses.

Buyer beware: the private-sale catch

The Sale of Goods Act contains some helpful implied conditions for buyers — most importantly that goods be of merchantable quality and reasonably fit for their purpose. The catch is that those particular protections generally apply only where the seller "deals in goods of that description" — in other words, a business or commercial seller. They do not apply to a one-off private seller offloading their own used belongings.

That is why a private, used-goods sale is largely "buyer beware." If you buy a used dresser from a stranger and it turns out to be more beaten up than you hoped, you generally cannot sue the private seller because it was not "merchantable" — that condition was never part of your deal in the first place. Two other points make this even more buyer-beware:

• "As is" wording. If the listing or the seller said the item was sold "as is," that language further limits your recourse. You agreed to take it in its current state, flaws and all.
• Inspection. Where you examined the goods before buying — say, you went and looked at the couch — defects that a reasonable examination ought to have revealed are generally not something you can later complain about. You had your chance to look.

I want to be careful here, because people sometimes reach for "consumer protection" laws and assume those rescue them. Broadly speaking, Ontario\'s consumer-protection regime is aimed mainly at deals between consumers and businesses, not private peer-to-peer sales between two ordinary people. So for a typical Marketplace deal between two individuals, I would not count on consumer-protection statutes to do the heavy lifting. If a business is genuinely on the other side of the deal, the analysis can shift — but that is a conversation to have about your specific facts.

Where a private seller can still be sued

Buyer-beware is not a free pass for sellers, and this is the part that gets lost. Even a purely private seller can absolutely be sued in several situations:

• Misrepresentation or fraud. If the seller lied about the item — actively told you something false to get the sale — buyer-beware does not protect them. Fraud is always actionable, no matter who the seller is.
• Failure to deliver. If you paid and got nothing, that is a plain breach. "Buyer beware" does not excuse a seller who simply kept your money.
• Goods that do not match their description. The implied condition that goods correspond to how they were described is not limited to business sellers. If the listing said "iPhone 14" and you received an iPhone 11, that is a different problem from the phone merely being worn — it does not match its description, and that is actionable.
• The seller did not actually own it. The implied condition that the seller has good title also applies broadly. If they sold you something they had no right to sell, that is a real claim.

So the practical line I draw is this: if your complaint is "this used thing turned out to be worn or imperfect," a private seller is often protected by buyer-beware. But if your complaint is "they lied," "they never delivered," "it was not what they said it was," or "it was not theirs to sell," buyer-beware does not save them — and you may well have a case. Notice that many of these started life as a handshake or a few chat messages; an agreement does not have to be on paper to bind, which I explain in whether a verbal contract is enforceable in Ontario.

I find it helps to picture the difference with a quick example. Say you buy a used lawnmower from a neighbour down the street. If it sputters and dies after two cuts because it was an old machine near the end of its life, and the seller never claimed otherwise, that is the buyer-beware risk you took on — there is usually no claim. But if that same seller told you it had a "brand-new engine put in last spring" when it did not, you are no longer complaining about an old item being old; you are complaining that you were lied to. Same lawnmower, same seller, completely different legal footing. The dividing line is almost always whether the seller said something untrue, failed to deliver, or sold you a different thing than they described.

Common situations I see

Over the years, the Marketplace disputes that come across my desk tend to repeat a handful of patterns. Each one sits differently against the buyer-beware rule.

The item never arrived. You paid by e-transfer for an item the seller agreed to ship or drop off, and it never came. This is one of the strongest scenarios — a clean failure to deliver. Buyer beware is irrelevant when the buyer received nothing at all. The whole fight here is usually about finding the seller, not about whether you have a claim.

Not as described. The listing promised one thing and you got another — different model, wrong size, missing parts, a "working" item that does not work. Where the gap is about description (you were sold a different thing than advertised), you generally have a claim even against a private seller, because goods are supposed to match their description.

Fake or broken. The "designer" bag is a knockoff; the "tested and working" console is dead on arrival; the sealed product is a box of rocks. If the seller knew and said otherwise, this is misrepresentation or outright fraud, and it is actionable regardless of buyer-beware. The challenge is proving they knew, which is where your screenshots earn their keep.

The seller did not pay you. You were the seller. The buyer took the item, or you shipped it, and the money never came — or the e-transfer was clawed back, or a cheque bounced. That is non-payment, and you can sue the buyer for the price. The same identification hurdle applies in reverse.

The kept deposit. You put down a deposit to hold an item, the seller backed out or vanished, and your money never came back. Depending on what was agreed, that can be a straightforward claim for the return of your money. Again, the legal side is usually easier than the practical side of tracking the person down.

Step-by-step: how to actually pursue it

If you think you have a real claim, here is the order I would work through it. Skipping the early steps is how people end up with strong stories and no way to enforce them.

1. Gather your proof before you do anything else

The first thing I do is lock down the evidence, because it disappears. Screenshot the listing, save the full message thread, and pull your proof of payment. Sellers delete posts and accounts the moment a deal goes bad, so capture everything now, even before you have decided whether to sue. More on exactly what to keep below.

2. Identify and locate the seller

This is the make-or-break step, and it comes early for a reason. You cannot sue a Facebook screen name — you need the seller\'s real legal name and an address to both start a claim and serve it. Work from whatever you have: the name on the e-transfer, a phone number, the pickup address, the vehicle ownership documents, anything they let slip. If you genuinely cannot identify them, the rest of these steps may not be possible — which is the hard truth I would rather you hear up front.

The good news is that more deals leave a trail than people assume. An Interac e-transfer usually records the recipient\'s registered name. A phone number can sometimes be tied back to a real person. If you went to their home to collect the item, you have an address. If the purchase was a registered asset like a car, the transfer paperwork carries their legal name and signature. Even details dropped in the chat — their workplace, their street, a partner\'s name — can be the thread you pull on. I would rather you spend an evening assembling these breadcrumbs before filing than discover at the courthouse that you have no one to name as the defendant.

3. Send a demand letter

Before filing anything in court, a firm demand letter is often worth a shot. It tells the seller you are serious, sets out what you want, and gives a deadline — and a surprising number of people pay up rather than face a claim. You can put one together quickly with the Ontario demand letter generator, and I explain how and why they work in demand letters explained.

4. File the claim in Small Claims Court

If the demand goes nowhere, you file a Plaintiff\'s Claim in Small Claims Court for the appropriate amount. You will need that real name and address, and you generally need an Ontario connection — the seller being here, the deal happening here, or the goods being delivered here — for an Ontario court to take the case. There is a filing fee and a defined process; I cover the cost to sue someone in Ontario so the budget does not surprise you.

The evidence that actually matters

The cases that hold together are the ones where the buyer or seller documented the deal. The cases that fall apart are the ones built on memory. Here is what I want to see, and what you should be saving in real time on every Marketplace deal of any value.

• The listing. Screenshot it the moment a deal is agreed, including photos and the exact wording of what was promised. This is the single most-deleted piece of evidence, because the seller controls it. If they said "brand new, never used," I want a picture of those words.
• The full chat thread. Save the entire conversation, top to bottom — not just the part that helps you. The back-and-forth is where promises get made ("yes it\'s unlocked," "I\'ll drop it off Friday"), and it is often the best proof of what was actually agreed.
• Proof of payment. The e-transfer confirmation, receipt, or bank record. This does double duty: it proves you paid, and the payment trail frequently reveals the seller\'s real name — which, as you now know, is half the battle.
• Photos of the problem. The broken item, the wrong model, the empty box, or proof that nothing ever arrived. Date-stamped where possible. This is what turns "they ripped me off" into something a deputy judge can actually see.

The theme running through all of this: save it early, and get the seller\'s real name and address at the time of sale. The single most common reason a winnable Marketplace dispute cannot be pursued is that the evidence — and the seller — evaporated before anyone thought to write things down.

Common mistakes I see

A few errors come up again and again with Marketplace disputes, and each one can quietly end a case before it starts.

Assuming every sale is guaranteed. People expect a private used-goods sale to come with the same protection as buying from a store. It does not. For a private seller, the default is buyer-beware, and "as is" wording plus your own chance to inspect narrow things further. If your only complaint is that a used item turned out to be used, you may not have a claim — and it is better to know that before you file.

Not getting the seller\'s real identity. This is the killer. Handing over money to "Mike T." with a profile photo of a sunset, and no real name, phone number, or address, leaves you with nobody to sue. I cannot stress this enough: the time to collect identifying details is during the deal, not after it has gone wrong and the account has vanished.

Suing for too little to be worth it. Court costs money and time, and a judgment is only useful if you can collect on it. Chasing a $50 item through the court system is almost never worth the effort. Be honest about whether the dollars justify the fight — I dig into that calculation in is it worth suing for $2,000 in Small Claims.

What happens in court

If you do file and the seller responds, a defended Small Claims case follows a streamlined path. After the claim is served, the defendant has a flat 20 days to file a Defence. From there, the case heads to a mandatory settlement conference before any trial — an informal meeting with a deputy judge who reviews the evidence, gives a candid read on how the case might go, and tries to broker a resolution. A large share of cases settle right there.

If it does not settle, you wait for a trial date and eventually present your case. This is where all that early evidence pays off: the listing, the chat thread, the payment record, and the photos do the talking. For a Marketplace dispute, a deputy judge is essentially asking two questions — what was actually agreed, and what actually happened — and your documents are how you answer both. Bring them organized, in order, and ready to hand up.

Winning, though, is not the same as getting paid. A judgment is a court order saying money is owed, not a cheque. If the seller will not pay voluntarily, you have to enforce the judgment — and against an individual who is hard to find or has little to collect from, that can be its own uphill climb. I walk through every enforcement tool in how to enforce a Small Claims judgment in Ontario.

Settlement considerations

In my experience, most of these disputes that go anywhere end in a settlement rather than a trial — and that is usually the smart outcome for both sides. A private individual who has been served with a claim and is looking at a court date often decides that paying something is cheaper than fighting. And for you, a settlement that gets money in hand beats a judgment you then have to chase.

When I weigh a settlement on a Marketplace case, I am thinking about the same three things I always raise: how strong the claim really is once buyer-beware is accounted for, how confident we are in the seller\'s identity and whereabouts, and whether they actually have the means to pay. A reasonable settlement that lands real dollars in your account is frequently worth more than a bigger number you might never collect. Settling is not giving up — for small private disputes, it is often the most efficient path to actually being made whole.

Key takeaways

• Yes, you can usually sue. A Marketplace deal gone wrong can support a Small Claims claim up to $50,000 — typically for breach of contract, misrepresentation or fraud, or non-payment.
• Private sales are "buyer beware." The Sale of Goods Act conditions of merchantable quality and fitness apply to business sellers, not one-off private sellers — and "as is" wording plus your own inspection narrow things further.
• But lies and no-shows are always actionable. Even a private seller can be sued for misrepresentation or fraud, for failing to deliver, for goods that do not match their description, or for selling something they did not own.
• Finding the seller is the real hurdle. A Facebook name is not enough — you need a real legal name and address to sue and serve, plus an Ontario connection, so capture those details during the deal.
• Do the math before you file. Weigh the amount against the cost, effort, and whether the seller can actually be found and made to pay.

Frequently asked questions

Can I sue someone over a Facebook Marketplace sale?

Yes. A Facebook Marketplace dispute is treated like any other deal — if there is a genuine claim, you can sue in Small Claims Court for up to $50,000. The usual grounds are breach of contract (the item never arrived, or was not as described), misrepresentation or fraud (the seller lied about what they were selling), or non-payment (a seller suing a buyer who never paid). The platform is just where you met; it does not change your legal rights. The harder part is usually identifying and locating the seller well enough to sue and serve them.

What if the item was sold "as is" or was used?

This is where private sales get tricky. For a one-off private seller, the deal is largely "buyer beware." The Sale of Goods Act conditions that goods be of merchantable quality and fit for purpose generally apply only to sellers who deal in goods of that kind — a business — not a private individual selling their old couch. "As is" wording further limits your recourse, and defects you could have spotted on a reasonable inspection usually are not covered. That said, even a private seller cannot lie about the item or sell something that does not match its description.

What if the item was never delivered?

Non-delivery is one of the cleaner claims. If you paid and the seller simply never handed over the goods — or never shipped them — that is a straightforward breach of contract, and "buyer beware" does not rescue a seller who took your money and gave you nothing. The same is true if they took a deposit and then vanished. Your real obstacles here are practical, not legal: you need the seller's real name and an address to sue and serve them, and you need an Ontario connection so a local court can hear the case.

What if the seller lied about the item?

Lying is always actionable, even for a private seller. If the seller told you the phone was unlocked and it was not, or swore the car had never been in an accident when it had, that is misrepresentation — and if they knew it was false, it edges into fraud. Buyer-beware protects an honest private seller from being on the hook for defects they did not know about; it does not protect a liar. The key is proof: the listing, the chat thread, and anything showing what you were actually promised before you paid.

How do I find out who the seller really is?

This is the single biggest practical hurdle. A Facebook profile name is rarely enough to sue or serve someone. Work backwards from whatever you have: the name on the e-transfer or payment record, a phone number, the address where you met or picked up the item, anything they said about where they live or work. If you bought a registered item like a vehicle, the ownership transfer documents carry their legal name. The time to collect this is at the moment of sale — get a name and a way to reach them before you hand over money.

Can I sue if I only have their Facebook name?

Realistically, no — not as a practical matter. To start a claim you have to name a defendant by their real legal name, and to serve them you need an address. A profile that says "John from Scarborough" does not give a court anyone to make an order against. You can sometimes piece together a real identity from payment records, a phone number, or a meeting location, but if all you have is a screen name and the account has gone dark, there may be nobody you can realistically pursue. That is exactly why I push people to capture identifying details during the deal.

Is it worth suing over a small purchase?

Sometimes yes, often no — it depends on the dollars and the seller. Court has a filing fee, takes time, and is only worth it if you can actually collect at the end. For a $60 item, the effort rarely makes sense. For a few hundred to a few thousand dollars, it can be very much worth it, especially if the seller is local and identifiable. I tell people to weigh three things: the amount, whether you can find and serve the seller, and whether they have any money to pay a judgment. A win against someone you cannot locate or collect from is a hollow victory.

What if the seller is in another province?

It gets harder. Ontario's Small Claims Court generally needs an Ontario connection — the seller being here, the deal happening here, or the item being delivered here — to take the case. If the seller is in another province or country, you may have to sue where they are, under their rules, which is often impractical for a small amount. Suing an out-of-province seller is one of the situations where the law is on your side in principle but the logistics quietly kill the case. For most Marketplace disputes, a local seller is what makes a lawsuit realistic.

Can a seller sue a buyer who did not pay?

Yes. The street runs both ways. If you sold something, the buyer took it (or you shipped it), and they never paid — or their e-transfer was reversed, or a cheque bounced — that is non-payment, and you can sue them for the price in Small Claims Court. The same hurdles apply in reverse: you need the buyer's real name and an address to sue and serve them, and an Ontario connection. Keep the listing, the messages confirming the deal, and any record of the handover, because the buyer may later claim the deal was different than it was.

What evidence do I need?

Four things, and you want all of them before you ever think about court. First, the listing itself — screenshot it, because sellers delete or edit posts. Second, the full message thread, top to bottom, showing what was promised and agreed. Third, proof of payment — the e-transfer record, receipt, or bank entry — which also helps establish the seller's identity. Fourth, evidence of the problem itself: photos of the broken or wrong item, or proof it never arrived. Save everything early; the moment a deal sours, the other side's posts and messages have a way of disappearing.

Final thoughts

"Can I sue over a Facebook Marketplace purchase?" has an honest answer that is more nuanced than yes or no. You can sue — the platform does not shield anyone, and a deal that went wrong is a real legal dispute. But two things decide whether it is worth doing. First, the buyer-beware rule means a private seller is not on the hook just because a used item turned out to be used; you need a lie, a no-show, a mismatch with the description, or a title problem to have a strong claim. Second, and just as important, you need to actually know who you are dealing with.

So the best protection is on the front end. On any Marketplace deal of real value, save the listing and the messages, pay in a way that leaves a record, and get the other person\'s real name and a way to reach them before money moves. Do that, and if the deal sours you will at least have a case you can pursue. Skip it, and even an obvious wrong can become impossible to chase. If you are weighing whether the math works, checking your deadline on the Ontario limitation period calculator is a sensible first step, since you generally have two years to act.

If you want a straight read on whether your specific Marketplace dispute is worth pursuing, call 416-554-1639 or book a free consultation. A short conversation can usually tell you whether you have a real claim, whether the seller can be found, and whether the numbers justify the fight — or whether you are better off walking away.
