Sanctions Law Services

We advise clients on a range of sanctions law matters and recommend the approach best suited to the transaction, asset, commercial relationship or dispute in question.

Sanctions Due Diligence

Sanctions issues can create significant risk in transactions, investments and commercial relationships, particularly where ownership structures, counterparties or assets span multiple jurisdictions. We advise clients on sanctions due diligence in connection with corporate transactions, property matters, investments and commercial arrangements.

Ownership and Control Issues

Determining whether an individual or entity is subject to sanctions is not always straightforward. We advise clients on issues involving beneficial ownership and control, helping them assess the position carefully and take proportionate steps to manage potential exposure.

Sanctions in Commercial Contracts and Transactions

Our team works closely with Barnes Law’s corporate, commercial and real estate lawyers on acquisitions, investments, property transactions and wider commercial arrangements.

Where sanctions risks arise, we advise on how they can be managed through contractual protections, transaction structures, practical safeguards and, where appropriate, licensing considerations. This includes matters involving counterparties, investors, beneficial owners or other parties connected with sanctioned persons or sanctioned jurisdictions.

Frozen Assets

Asset freezes and payment restrictions can place immediate pressure on businesses, investors and individuals. We work to find commercially effective solutions while protecting our clients’ interests in complex and time-sensitive situations.

Sanctions-Related Disputes

Sanctions can give rise to complex commercial disputes, particularly where they affect contractual performance, payment obligations, asset recovery or the enforcement of rights. We advise clients on sanctions-related disputes in both domestic and cross-border matters, including litigation and arbitration.

Frequently Asked Questions (FAQs)

What sanctions matters do you advise on?

We advise businesses, business owners and high-net-worth individuals on a broad range of sanctions-related matters. This includes sanctions due diligence, ownership and control issues, frozen assets, payment restrictions, commercial contracts, transactions, licensing and reporting considerations, and sanctions-related disputes.

Do you advise clients with international interests?

Yes. We advise on sanctions issues arising in domestic and cross-border matters, including where transactions, assets, counterparties or ownership structures involve multiple jurisdictions. We support clients throughout the UK, Europe and the Middle East in managing complex commercial and sanctions-related issues.

What is meant by ownership and control for sanctions purposes?

A person or entity may be affected by sanctions not only because they are named on a sanctions list, but also because they are owned or controlled by a designated person. Assessing ownership and control can be complex, particularly where corporate structures, trusts, nominees or overseas entities are involved. We advise clients on these issues in the context of transactions, investments and commercial relationships.

What should I do if I discover a sanctions issue during a transaction?

Sanctions concerns should be addressed as soon as they are identified. The right next step will depend on the parties involved, the nature of the transaction, the ownership structure and any restrictions affecting funds, assets or contractual performance. We advise clients on assessing the position quickly and considering how the transaction or arrangement can be managed appropriately.
