Sanctions clauses in contracts – 3 lessons from recent cases you can apply

International contracts can no longer be imagined without sanctions clauses. Just a few years ago, such provisions were considered rare, but today they have become a mandatory standard for companies operating in global markets. The reason is simple: sanctions are expanding and affect not only banks and state-owned corporations but also private transactions across a wide range of industries. Regulators strictly penalize those who fail to account for sanctions risks in their contracts. Recent case law shows that even formally lawful agreements can be blocked or declared invalid. This is why businesses must understand which formulations truly work and which only create the illusion of protection. In this article, we will examine what a sanctions clause is, its key elements, and three lessons from real cases that can help companies avoid costly mistakes.

What is a sanctions clause?

A sanctions clause is a contractual provision that regulates the actions of the parties in the event of the imposition or amendment of sanctions. It protects businesses from risks associated with the inability to perform obligations and reduces the likelihood that the contract will be considered in violation of international law. With the tightening of global sanctions policies, such clauses are becoming an essential element of international agreements.

Unlike general provisions requiring the parties to «comply with the law», a sanctions clause specifically addresses sanctions regimes and takes their unique features into account. It allows the parties to:

1. Define which sanctions will trigger the clause (e.g., UN, EU, OFAC, OFSI, or local authorities’ measures);
2. Provide a mechanism for suspending or terminating obligations;
3. Allocate risks and losses between the parties;
4. Require timely notification of any changes in sanctions status;
5. Establish warranties of good faith and compliance with applicable sanctions regulations.

A sanctions clause serves a dual function: both legal and practical. On the one hand, it reduces the risk of the contract being declared invalid; on the other, it provides companies with a structured mechanism for responding to external restrictions. Without such a clause, businesses remain unprotected and are forced to improvise when confronted with sanctions, which often results in financial losses or litigation.

Key elements of an effective sanctions clause

An effective sanctions clause must be specific and detailed. Its purpose is not just to mention sanctions, but to clearly define the actions the parties must take in different scenarios. Below are the main elements that help companies safeguard their interests and mitigate risks.

Clear triggering events

The clause should clearly specify which sanctions regimes apply: UN, EU, US (OFAC), UK (OFSI), and the local laws of the jurisdiction where the contract is performed. Without such specificity, the parties risk disagreements; one may refer to European rules, while the other relies on national legislation. Clear triggers remove ambiguity and allow the parties to understand in advance under what circumstances the contract may be amended or terminated.

Suspension of performance

It is useful to include a mechanism for temporarily suspending obligations if sanctions make performance difficult but not permanently impossible. This avoids immediate termination and allows the relationship to be maintained until the situation is clarified. Such an approach is particularly valuable in long-term contracts, where abrupt termination can cause significant losses for both parties.

Termination rights

The clause should provide for the right to terminate the agreement without penalties if performance becomes illegal or impossible due to sanctions. This releases the parties from further obligations and reduces the likelihood of litigation. Including such provisions also demonstrates to regulators and counterparties that the company complies with international law and acts in good faith.

Allocation of losses

One of the most sensitive issues is who bears the costs if the contract is suspended or terminated. The clause should clearly set out the rules for refunding advance payments, covering expenses, and addressing third-party liabilities. The clearer the allocation of losses, the lower the risk of disputes and additional claims.

Notification obligations

The parties should be required to notify each other of sanctions-related developments within strict deadlines. Typically, contracts stipulate 3–5 business days for written notice. Without such provisions, a company may suddenly face a blocked transaction without sufficient time to take protective measures.

Compliance warranties

The contract should include assurances from both parties that, at the time of signing, they and their beneficial owners are not subject to sanctions. In addition, each party should undertake to comply with all applicable regimes throughout the life of the contract. This type of warranty reduces the risk of the contract being invalidated and provides a basis for claims if a violation occurs.

Three lessons from recent case studies

Sanctions clauses are increasingly becoming the subject of litigation. Recent practice shows that courts carefully analyze not only the fact of their existence but also how exactly they are drafted and applied.

Case 1. The presence of a clause does not eliminate the need to prove violations

In Kuvera Resources Pte Ltd v. JPMorgan Chase Bank NA SGCA 28, the bank refused to honor a letter of credit, citing the sanctions clause. The basis was internal red flags suggesting that the vessel might belong to a sanctioned party. However, the Singapore Court of Appeal held that the mere existence of such a clause does not grant the bank absolute immunity. It is necessary to present evidence that the specific transaction actually violates the sanctions regime.

Conclusion: a sanctions clause is effective only when combined with clear conditions of application and the ability to prove the existence of a sanctions risk.

Case 2. General formulations are too vulnerable

In British and European practice, there have been cases where companies limited themselves to the phrase «the parties must comply with applicable law». Courts have found such provisions too vague and unsuitable for protection. For example, legal reviews note that UK courts emphasize that a general reference to the law does not replace a specific sanctions clause tailored to OFAC, EU, or OFSI regimes.

Conclusion: generic formulations do not work. A clause must directly specify the applicable regimes, the notification process, and the consequences.

Case 3. Courts assess the parties’ actual conduct

In cases involving the circumvention of sanctions through intermediaries or subcontractors, companies attempted to rely on the existence of a clause in the contract. However, courts examined the actual performance and concluded that such schemes violated sanctions regimes even if the contract formally contained the required provisions.

Conclusion: a sanctions clause cannot be used as a shield. If a business is factually involved in circumventing sanctions, it will not be protected from liability.

Practical recommendations for businesses

Recent practice shows that sanctions clauses provide real protection only when they are drafted precisely and applied in conjunction with other compliance mechanisms.

Define sanctions regimes in advance

The clause should specify which sanctions regimes it covers, along with the local laws of the counterparty’s jurisdiction. This helps avoid disputes over which restrictions apply. Case law shows that generic wording such as «in the event of sanctions» lacks sufficient legal force. The more detailed the triggers, the more reliably the clause works in practice.

Establish notification rules

The contract should contain a clear procedure for notifying the parties of sanctions-related changes: deadlines, format, and communication channels. Best practice is written notice within 3–5 business days, with supporting documents attached. This gives the parties time to take protective measures, such as suspending payments or revising the terms. Without such a mechanism, the agreement becomes vulnerable and more prone to disputes.

Use temporary suspension

It is useful to include a mechanism for temporarily suspending performance if sanctions create uncertainty but do not make the contract permanently unenforceable. This allows the parties to preserve their relationship while awaiting clarification from regulators. Such a tool is particularly important in long-term deals, where immediate termination could cause significant losses. Suspension of performance also demonstrates good faith and reduces reputational risks.

Allocate costs and losses in advance

One of the most contentious issues is the allocation of financial consequences arising from sanctions. The contract should specify in advance who bears the costs in case of suspension or termination: refunding prepayments, covering expenses, or settling third-party liabilities. Clear allocation of losses reduces the likelihood of litigation and speeds up dispute resolution. This is especially critical in industries with substantial advance payments, such as energy or logistics.

Link to company policies

A sanctions clause should not exist in isolation, it should be aligned with the company’s internal KYC/AML policies. This helps demonstrate that the business has taken sufficient measures to manage risks from the outset. Cross-references to compliance documents show banks and regulators a systematic approach. Such integrated contract design significantly enhances resilience.

Review and update regularly

Sanctions regimes change constantly, meaning even a well-drafted clause may become outdated within a few months. It is recommended to review contracts at least annually, and every six months when operating in high-risk jurisdictions. Regular updates ensure that new sanctions lists and regulatory requirements are incorporated in time. This approach reduces the likelihood that a contract will suddenly become unenforceable.
