Bookmaker won't pay out your winnings: what you can do

Your bet won, but the withdrawal is stuck, the account is frozen or the winnings have been taken back. Here is why bookmakers do this, which reasons hold up, and the order in which to push: evidence, a written complaint, dispute resolution, the regulator and, last, the courts.

General information, not legal advice

This page describes the general position as of October 2026, with Austria, Malta-licensed bookmakers and Slovakia as examples. Whether a bookmaker may hold back your money depends on its terms, its licence and the facts of your case. For large amounts, get advice from a consumer body or a lawyer.

The reasons bookmakers give

A withheld payout is rarely explained in one sentence. In practice almost every case falls into one of these groups, and each has a different chance of being resolved:

Verification is not finished. The most common reason by far. Before the first withdrawal, or once deposits or winnings pass an internal threshold, the bookmaker asks for ID, proof of address or proof of payment method. Until it's done, nothing is paid. See source of funds checks for the bigger version of this.
Payment method rules. Many bookmakers pay out only to the method you deposited with ("closed loop"). A withdrawal to a different bank account or wallet is rejected or delayed.
Bonus terms. Winnings from bonus money count only once the wagering requirement is met. A withdrawal request before that can cancel the bonus and the winnings made with it.
The bet was voided or re-settled. An obvious-error ("palpable error") clause, a tennis retirement or an abandoned match changes the result after the fact. That case has its own guide: voided bets and palpable errors.
A suspected breach of the terms. Multiple accounts, an account used by someone else, a VPN or a location outside the licence area, or suspected match fixing. Here bookmakers often freeze the whole balance. See betting on someone else's account and betting with a VPN.
Maximum payout. Most terms cap the payout per bet, per day or per customer. Winnings above the cap are not paid, even if the bet was accepted.

What is generally not a valid reason: that you win often, compare prices or place sure bets. A bookmaker may limit your stakes or close the account for the future (bookmaker limits explains how that works), but closing an account doesn't normally entitle it to keep a balance from correctly settled bets.

Step 1: secure the evidence

Do this before you write a single message, because accounts sometimes become inaccessible once a dispute starts.

Screenshots of the bet slip or bet history: bet ID, event, market, price, stake, time of placement and the settled result.
The account balance and the transaction history, including deposits and the pending or rejected withdrawal.
Every message from the bookmaker: emails, chat transcripts (ask for a copy), notices in the account.
The version of the terms that applied when you placed the bet. Save the page as a PDF with the date; the terms guide shows which clauses to look for.
The licence details from the footer or imprint: the regulator, the licence number and the company name.

If verification documents were requested, send exactly what was asked for, in readable quality, and note the date you sent it. Many "won't pay" cases end here.

Step 2: complain in writing

Chat agents can rarely change a decision and chats are easy to lose. Write to the complaints address or contact form named in the terms, keep it factual and set a deadline. Licensed operators must have a complaints procedure, and under Malta's rules, for example, the internal complaint is the first step before any dispute body.

Template

Subject: Formal complaint: withheld winnings, account [username]

Dear Sir or Madam,

On [date] I placed bet no. [bet ID] on [event, market] at odds of [odds] with a stake of €[amount]. It was settled as won on [date]. On [date] I requested a withdrawal of €[amount], which has not been paid / my account was restricted on [date].

I have provided all documents you requested on [dates]. Please state the specific clause of your terms on which you rely to withhold the payment, and the facts that you say meet it.

I ask you to pay out €[amount] to my registered payment method within 14 days. If we cannot resolve this, please name the alternative dispute resolution body you work with; I will otherwise refer the matter to it and to your licensing authority.

Kind regards,
[name, account email]

Ask for a final answer (often called a "final response" or "deadlock letter"). Dispute bodies usually want to see that the internal procedure was used first.

Step 3: dispute body or regulator, depending on the licence

The licence decides who can help. It's shown in the footer or imprint of the bookmaker's site.

Malta Gaming Authority (MGA). Many bookmakers serving Austria hold an MGA licence. If the internal complaint doesn't resolve the dispute, an MGA licensee must refer you to an approved alternative dispute resolution (ADR) body, free of charge to you; its terms name the body. The MGA's own Player Support Unit no longer decides the merits of individual disputes (since April 2019), but it still takes reports of unlawful or unfair conduct by licensees.
Austrian Land licence. Sports betting in Austria is regulated by the nine federal states, not by the federal gambling act. The Land government that issued the permit (for example Lower Austria or Upper Austria) supervises the operator. It doesn't rule on a single bet, but a written report about a licensee that doesn't pay can trigger a check of its obligations.
Slovak licence. Online betting in Slovakia is only legal with operators licensed by the gambling regulator ÚRHH (Úrad pre reguláciu hazardných hier) under Act 30/2019. You can send ÚRHH a complaint (podnet) about a licensee. For a consumer dispute, the Slovak Trade Inspection (SOI) acts as the general ADR body.
Another EU or EEA licence. The European Consumer Centre in your country gives free help with cross-border consumer disputes (in Austria: Europäisches Verbraucherzentrum Österreich).
A licence outside the EU, or none. In practice, nobody will enforce anything for you. Some offshore licences mention a complaints channel, but don't count on it.

Send the dispute body the same evidence pack as in step 1, plus your complaint and the bookmaker's final answer.

Step 4: court, and bets with unlicensed operators

The last resort is a claim in court. Consumers can normally sue a bookmaker in the courts of their home country (Brussels Ia Regulation, Articles 17 to 19). For cross-border claims up to €5,000 the European Small Claims Procedure is a cheaper, written procedure. For larger amounts, legal advice usually pays for itself; check first whether you have legal expenses insurance.

A separate question is whether you can reclaim losses from an operator without the right licence. In Austria the Supreme Court (OGH) lets players reclaim online casino losses from operators without an Austrian licence (for example 1 Ob 182/22d). Sports betting is different: it is not gambling under the federal act, and in 1 Ob 176/22x the refund claim for online sports bets failed. So the "illegal gambling" route rarely helps with sports bets in Austria. In Germany, the European Court of Justice ruled in April 2026 (C-440/23) that member states may attach civil consequences, including refunds, to unlicensed online gambling; how that applies to individual sports-betting claims is still being worked out. In Slovakia the gambling act sanctions unlicensed operators rather than players, and the operator sits outside Slovak supervision, which makes collecting anything hard.

The practical lesson is the same everywhere: check the licence before the first deposit. ArbVantage shows a neutral licence flag for every bookmaker (for example "Not licensed in Austria"), so you can decide with the facts in front of you.

What is really at stake in a sure bet

A withheld payout hurts sure bettors more than most, because the dispute is about the whole payout, not the small margin.

Worked example

You find a two-way sure bet at 2.10 (Bookmaker A) and 2.05 (Bookmaker B) and split €1,000: €494 at A and €506 at B. A pays €494 × 2.10 = €1,037.40 if its side wins, B pays €506 × 2.05 = €1,037.30. Either way about €37 more than you staked, or a margin of about 3.7%.

A's side wins. The €506 at B is lost, as planned. But A freezes the account and doesn't pay out the €1,037.40. Until that is resolved, you are not €37 up; you are €1,000 down, the full amount you staked across both bookmakers.

That is why it makes sense to withdraw winnings regularly instead of building up large balances, to finish verification before you bet seriously, and to keep stakes at any single bookmaker in proportion to what you'd be comfortable having in dispute. The risks of arbitrage betting covers this and the other ways a sure bet can go wrong.

What we can and can't do

ArbVantage is software that finds price differences and works out stakes. We are not a party to your contract with any bookmaker, we can't intervene in a dispute, and we don't give legal advice. What helps: the bet tracker keeps a dated record of every bet you log, including stake, price and result, which is useful evidence if you ever need it.

The steps in short

Find out which reason the bookmaker gives: verification, payment method, bonus terms, a void, a suspected breach or a payout cap.
Save the bet history, balance, transactions, all messages, the terms that applied and the licence details.
Send a written complaint with the facts, ask for the clause relied on, and set a 14-day deadline.
If there is no agreement, go to the ADR body named in the terms, the licensing regulator or the European Consumer Centre.
For larger amounts, get legal advice and consider a claim, for example through the European Small Claims Procedure up to €5,000.

Frequently asked questions

Is a bookmaker allowed to keep my winnings?

Only if its terms give a valid reason that actually applies, such as unfinished verification, unmet bonus conditions, a payout cap or a genuine breach of the terms. Winning often or placing sure bets is not such a reason; it can lead to limits, but a balance from correctly settled bets should normally be paid out.

How long can a withdrawal take?

There is no single legal deadline. The terms usually state processing times of a few working days once verification is complete. If a payout is held for weeks without a clear reason, complain in writing and set a deadline.

Does the MGA help if a bookmaker won't pay?

Not directly with the money. After your complaint to the bookmaker, an MGA licensee must refer you to an approved dispute resolution body free of charge. The MGA itself no longer decides individual disputes, but you can report unlawful or unfair conduct to it.

Can I get my money back from a bookmaker without a licence?

It is hard. In Austria refund claims work for online casino losses but have generally failed for sports bets, and operators outside the EU are difficult to sue. Check the licence before you deposit.
