Herbert Smith tax partner Neil Warriner has become head of the firm's tax group following Heather Gething's decision to step down from the role.
Gething, who has led the group since 2001, has taken on the new role as head of tax planning and tax disputes, with a focus on investment banks, financial institutions and insurance companies.
Warriner has been a corporate tax partner at Herbert Smith since 1994 and specialises in all tax aspects of land and property transactions and tax issues arising in the energy sector.
Gething recently received her certificate of eligibility to apply for higher rights of audience which means that from the autumn onwards she will be able to represent clients before the Commissioners and higher courts.
Gething said revenue and customs was becoming more litigious and the number of tax cases was on the rise.
"Contentious skills, knowledge and experience are of great value when dealing with tax planning issues and the expertise we can offer both from a tax perspective and through the firm's leading litigation practice bring significant benefits to our clients,” she said.
