A Curaçao appeals court has ruled that online casinos may include contractual terms preventing players from transferring financial claims to third parties. The decision could affect organisations that pursue gambling claims on behalf of players, but it does not end the underlying dispute. Gaming Services Provider still has to prove which versions of the casino terms applied to the players whose claims are before the Court.
What the Curaçao court actually decided
The Joint Court of Justice has confirmed an important point for Curaçao-licensed online casinos: a term that prevents a player from assigning a financial claim to somebody else is not automatically unreasonable. The judgment arose from an appeal involving Gaming Services Provider, or GSP, Stichting Belangenbehartiging Gedupeerden Online Kansspelen, known as SBGOK, and a group of players. The dispute is not simply about whether money is owed. It is also about whether the players were bound by the casino terms and whether some of them were legally able to transfer their claims to an organisation that would pursue the casino on their behalf.
GSP holds a Curaçao licence and makes that licence available to various online casinos. In the cases before the Court, players say casinos wrongfully withheld money that should have been paid or returned. Five players transferred their claims to SBGOK, while two other players are pursuing their claims against GSP themselves. The amounts vary from several thousand to tens of thousands of US and Canadian dollars. That makes the assignment question more than a technical contractual issue. If the claims were validly transferred, SBGOK could act as claimant. If the transfer was blocked by enforceable terms, the legal route becomes much narrower.
The Court’s ruling does not mean every anti-assignment clause used by every casino is automatically valid. Instead, it establishes that such a restriction can in principle form part of the contract without being inherently unreasonable. The next question is factual: which version of the terms applied to each player, and can GSP prove that those terms were properly made available when the accounts were created? That is why the litigation continues despite the broader legal point having been answered.
How acceptance of online terms became central to the case
GSP argued that players could not create accounts or gamble without accepting the relevant terms and conditions. The terms were available through a link, and users had to check a box confirming acceptance. SBGOK challenged the strength of that evidence, arguing that GSP had not shown that the players were able to store the terms for later reference at the point when the agreements were made. That detail matters because electronic-contract rules require general terms to be provided in a way that allows them to be saved or otherwise retained.
The Court did not accept the idea that the absence of a dedicated download or save button automatically invalidated the terms. What mattered was whether the terms had been made available in a form that could be stored for later use. The judges also rejected the suggestion that an operator must prove that a particular player actually opened and read the terms. In online contracting, acceptance can still be effective even when a user chooses not to read every clause, provided the terms were made properly available and the acceptance mechanism itself was valid.
That finding is notable because it differs from an earlier case involving Usoftgaming. In that dispute, the operator was unable to show adequately that players could save the applicable terms, and the company was therefore unable to rely on them. The newer judgment does not erase that earlier approach. If anything, it sharpens the practical lesson for operators: the existence of terms is not enough. The casino must be able to demonstrate how those terms were presented, which version applied and whether the player had a real opportunity to retain them.
Why assignment restrictions matter for player claims
The most consequential part of the judgment concerns the transfer of claims. SBGOK and similar organisations rely on players assigning claims so that the organisation can pursue recovery against gambling companies in its own name. The Court held that an online casino may include a valid clause preventing that transfer. The judges considered such a restriction capable of serving legitimate purposes, including the checks gambling operators carry out to prevent fraud and money laundering. From that perspective, keeping the claim tied to the original account holder can have a compliance rationale rather than being only a way to make litigation harder.
The Court also indicated that a valid prohibition cannot necessarily be bypassed simply by changing the legal structure of the arrangement. If SBGOK is not formally assigned the claim but is instead appointed to collect the money for the player, that may still conflict with the substance of the restriction depending on how the arrangement works. The judgment therefore looks at more than labels. What matters is whether the contractual prohibition genuinely keeps the claim with the player and whether a third party is effectively stepping into the same position through another mechanism.
For claim-management organisations, this could alter the way cases involving Curaçao-licensed operators are assembled. A model built around collecting many assigned claims may be less straightforward where the underlying terms contain an enforceable prohibition. At the same time, the ruling does not remove the player’s own right to pursue a claim. Two of the players in the current proceedings are already doing exactly that. The decision changes who may hold and enforce the claim, not whether an underlying dispute about withheld money can exist.
The case is not finished
The Court has not yet made a final decision on every player’s claim. GSP must still prove which terms and conditions were in force when the relevant accounts were opened in 2022. That is a particularly important issue because the evidence is not perfectly aligned. The source material points to the example of online casino Betcoin, where article numbers cited in the case do not match the numbering in some of the documents submitted to the Court. A broadly valid legal principle will not help GSP if it cannot connect the correct contractual wording to the correct player and date.
SBGOK will be allowed to submit what it believes are the correct historical versions of those terms. Both sides have until October 6, 2026 to provide the additional documents requested by the Court. Only after that evidentiary stage can the judges continue assessing how the assignment restriction affects the individual players. The next phase is therefore likely to be document-heavy, because the dispute now turns on version control, account dates and the precise wording that was actually incorporated into each agreement.
That distinction is easy to miss when reading the headline. The Court has said that an assignment prohibition can be lawful. It has not said that GSP has already proved that every player in the case agreed to one. The difference between those two propositions is the difference between a general rule and the application of that rule to a particular contract. The final outcome for the players will depend on the latter.
What the judgment may mean for Curaçao-licensed operators
For online casinos using Curaçao licensing, the case places renewed attention on contract administration. Operators that want to rely on restrictions in their terms need to keep historical versions, record when changes were made and be able to show which version a player accepted. A clause can be legally acceptable in the abstract and still be unusable in a specific dispute if the operator cannot prove that it formed part of that player’s agreement. In practice, that makes record keeping almost as important as the wording itself.
The ruling may also encourage casinos to review how clearly assignment clauses are drafted. A vague clause could create further arguments over whether it prevents a formal transfer of the claim, collection on behalf of the player, litigation funding or some combination of those arrangements. The Court’s reasoning shows that these distinctions matter. Because gambling businesses also have anti-fraud and anti-money-laundering obligations, the commercial and compliance reasons for keeping claims linked to verified account holders are likely to receive close attention in future disputes.
For players, the main lesson is different. Terms about dispute resolution, withdrawals and transfer of rights may have consequences long after the account is opened. Checking a box can create contractual obligations even when the user does not read every clause, provided the terms were properly made available. That makes it useful to save or archive the terms that apply when an account is created, especially if significant balances or withdrawals later become disputed.
Why this ruling matters beyond the individual claims
The litigation sits at the intersection of online contracting and gambling regulation. On one side is the ordinary rule that businesses can set contractual conditions if they are properly incorporated and not unfair. On the other is the reality that gambling disputes often involve identity checks, payment records and regulatory controls that make the original account holder especially important. The Court’s acceptance of assignment restrictions reflects that context without eliminating the need for operators to prove their paperwork.
The result is therefore more nuanced than a simple win for casinos or a loss for players. GSP gained support for the proposition that a casino can prohibit assignment of claims. SBGOK still has room to challenge whether the relevant terms were actually in force and properly incorporated. The individual players still have underlying claims that must be assessed. And the Court has left the door open for the evidence submitted in October to determine how the general principle applies to each case.
Until the additional documents are filed and reviewed, the most accurate reading is that Curaçao-licensed casinos have clearer authority to include anti-assignment clauses, but enforcement remains dependent on contract evidence. For organisations that aggregate player claims, that is a meaningful obstacle. For operators, it is also a reminder that terms and conditions only become useful in court when they can be traced, dated and connected to the customer who accepted them.
