CIS Disputes

The majority of our lawyers have extensive experience in conducting commercial litigation on behalf of CIS clients in the English courts and other related jurisdictions (such as the British Virgin Islands, Cyprus, Latvia​, ​Tajikistan​, ​Kyrgyzstan​ and ​Kazakhstan).

They have also frequently represented CIS clients in international arbitrations.

Members of our team have acted in leading cases emanating from Russia, Georgia, Ukraine and other countries in the region.
There are common themes running through most disputes which originate from within the region, and we understand the commercial and business environment in which our clients operate. These disputes also give rise to complex issues of conflicts of laws and jurisdiction, both of which we regularly advise on. Our substantial experience of handling these disputes gives our clients a real strategic advantage over their opponents. Members of our team have acted in some of the recent leading cases emanating from Russia, Georgia, Ukraine and other countries in the region.

Signature is uniquely placed to be able to provide high quality focused advice to those involved in CIS related disputes.

With one of the few senior English qualified Russian speaking litigators, we are able to offer clients in the region high quality advice which truly understands their needs. Ranked in Chambers and Partners and The Legal 500, Natalia Chumak is said to be a “steely litigator with excellent litigation instincts”. Clients highlight her “good handle on treaty arbitrations”.
