Bookmaker terms and conditions: 10 clauses to check before a sure bet

The ten clauses, with examples

1. Obvious errors ("palpable error")

Almost every bookmaker may void or re-settle bets at a price that was clearly wrong. Check how the clause defines an error, whether the bet is voided or re-settled at the correct price, and how long after settlement a correction is allowed. Sure bets often sit on exactly the prices a bookmaker later calls a mistake. More in voided bets and palpable errors.

2. Tennis retirements

Three rules are common: the bet is void unless the match is completed; the bet stands once a set (or another threshold) is completed and the advancing player wins; or the bet stands as soon as the first ball is served. Two bookmakers with different rules can turn a sure bet into a loss (see the example below).

3. Overtime and extra time

In football, standard markets cover 90 minutes plus stoppage time; extra time and penalties count only in markets like "to qualify". In ice hockey the three-way market (1X2) usually covers regular time only, while the moneyline usually includes overtime and shootout. Basketball and American football markets mostly include overtime. Read which rule applies to each market, not just the sport.

4. Abandoned and postponed matches

Typical rules: bets are void if a match is abandoned, except markets already decided (for example a first-half result); a postponed match stands only if it is played within a time window, often 24 or 48 hours, or within the same week at some books. Different windows at your two bookmakers can leave one leg void and the other live.

5. Maximum payout

Most terms cap what can be won: per bet, per day, per week or per customer, sometimes lower for smaller leagues or special markets. Winnings above the cap are simply not paid. A sure bet whose payout at one bookmaker exceeds that cap is no longer a sure bet.

6. Bet acceptance, stake limits and cancellation

The bookmaker may refuse a bet, accept only part of the stake or change the maximum stake for your account at any time (see stake factoring). Check also what happens to bets placed after an event has started ("late bets") and whether a bet counts only once the bookmaker confirms it.

7. Account closure and the remaining balance

Bookmakers can close accounts. The important part is what happens to your money: a fair clause says open bets are settled normally and the balance is paid out. Clauses that allow keeping the balance should name clear reasons, such as fraud or a serious breach.

8. Bonus terms

Wagering requirements, minimum odds, time limits and the rules on which bets count. Many bonus terms exclude bets on both sides of a market or "low-risk betting", and some explicitly mention arbitrage. A breach can cancel the bonus and the winnings made with it. More in free bets.

9. One account, identity and location

One account per person (sometimes per household), only for your own use, only from permitted countries, and no VPN. Breaches typically lead to voided bets and withheld winnings. See betting on someone else's account and betting with a VPN.

10. Withdrawals and verification

Payout only to the deposit method, verification before the first withdrawal, possible source of funds checks, processing times and any withdrawal fees. These clauses decide how fast your money moves between bookmakers. See source of funds checks.

Where to find these clauses

The relevant rules are usually spread over several documents, linked in the footer of the bookmaker's site:

• General terms and conditions: account, identity, location, closure, withdrawals, obvious errors, maximum payout.
• Betting rules or sports rules: settlement per sport and market, retirements, overtime, abandoned matches, dead heats. This is often a long document of its own and the most important one for sure bets.
• Bonus or promotion terms: general bonus rules plus the specific terms of each offer.
• Responsible gambling and privacy pages: limits, self-exclusion and what happens to your data during verification.

Use the browser's search (Ctrl+F or "Find on page") with words like "retire", "overtime", "abandon", "maximum", "error" or "void" to jump to the right section.

Keeping track of changes

Terms change. Bookmakers usually announce changes in the account or by email and ask you to accept them on the next login. For consumers, changes to the detriment of the customer generally need clear notice; unclear or one-sided clauses can be unenforceable under EU unfair-terms law. What counts for a bet is usually the version in force when you placed it, so:

• Save the betting rules as a PDF with the date when you start with a bookmaker, and again whenever you are asked to accept new terms.
• Note the version number or date shown at the top or bottom of the terms.
• Read the change notice before clicking "accept": it often names the changed sections.

Spotting conflicts between two bookmakers

The classic "sure bet" that isn't one: both bookmakers offer the same market name, but settle it under different rules.

Other common conflicts: ice hockey regular time at one book against overtime-inclusive at the other; different windows for postponed matches; "player must start" versus "player must take part" in player markets; and different handling of dead heats. When in doubt, compare the two rule texts for the exact market before you bet, or choose a market where both rules are the same. Other ways sure bets go wrong are in arbitrage betting mistakes.

Checklist before you bet

1. Check the licence and whether the bookmaker accepts customers from your country.
2. Read the account, identity, location and withdrawal rules once, and finish verification early.
3. For each sport you bet, compare the rules on retirements, overtime and abandoned or postponed matches at both bookmakers.
4. Check the maximum payout for the market and make sure your planned payout is below it.
5. If a bonus is involved, read its wagering rules and any exclusions before you bet with it.
6. Save the current terms and betting rules as a dated PDF and note any changes you are asked to accept.

Frequently asked questions

Do I have to read all of a bookmaker's terms?

Not every line, but the ten clauses on this page are worth reading once per bookmaker: obvious errors, retirements, overtime, abandoned matches, maximum payout, bet acceptance, account closure, bonuses, account and location rules, and withdrawals.

Can bookmakers change their terms?

Yes, usually with notice in the account or by email and a request to accept. For consumers, unclear or one-sided changes can be unenforceable. As a rule, a bet is settled under the version that applied when you placed it, so save the terms with a date.

What applies if two bookmakers have different rules?

Each bookmaker settles its own bet under its own rules. That is why two legs of a sure bet can end differently, for example one void and one lost after a tennis retirement. Compare the rules for the exact market before you bet.

Where are the settlement rules for each sport?

Usually in a separate document called betting rules or sports rules, linked in the footer of the bookmaker's site. The general terms cover the account, withdrawals and closure; the sports rules cover how each market is settled.
