SERVICES AND INFORMATION

Criminal Law

With one of the top criminal law practices in Ukraine, Ilyashev & Partners provides comprehensive legal defense in criminal cases.

 

The firm’s criminal defense lawyers represent Ukrainian and international companies, business owners, top executives and investors in criminal cases related to economic crimes, official misconduct, financial offences and corporate conflicts. The practice also covers criminal law risks associated with sanctions, restrictive measures and export control regimes.

 

A significant part of the team’s work involves crisis response for businesses during criminal investigations, including defending clients during searches, detentions, asset seizures and other investigative actions. We assist companies and their management in promptly developing a legal strategy, minimising reputational and operational risks, and establishing an effective approach to interaction with law enforcement authorities.

 

A separate category of cases involves criminal proceedings related to public procurement, infrastructure projects and contracts in strategic sectors of the economy, particularly in the defence industry. The firm’s lawyers represent companies and their employees in cases involving alleged violations of public procurement regulations, the use of public funds and the performance of government contracts.

 

The team conducts internal corporate investigations, analyses potential legal violations and develops strategies for interaction with law enforcement authorities. It also advises companies on managing criminal law risks, compliance matters and preventing offences in business operations.

 

The firm has experience handling cases involving virtual assets and cryptocurrencies, including investigations into financial transactions with crypto-assets, defense in criminal proceedings related to fraud, illegal circulation or money laundering involving cryptocurrencies, and advising on legal risks associated with digital asset operations.

 

The practice also covers cases involving the liability of medical professionals and healthcare institutions, including proceedings related to alleged medical malpractice, improper medical care and professional negligence.

 

The firm’s team has experience representing clients in proceedings related to road traffic accidents, theft and other criminal offences. Ilyashev & Partners represents both suspects and defendants as well as victims, ensuring the protection of their rights at all stages of criminal proceedings.
