Limitation of liability and insurance
Any liability shall be limited to the amount paid out under our professional indemnity insurance and the applicable deductible (eigen risico). Please see our general terms and conditions of business for other limitations with respect to our liability.

Clients based in England and Wales should consider that the Solicitor Regulation Authority Indemnity Insurance Rules 2013 are not applicable. As a result the indemnity insurance position is different from that applicable to a firm located in England and Wales, where – for example - the minimum insured amount required by the Solicitors Regulations Authority currently varies between £2-3 million (depending on the type of work). If you have any further queries on this, please contact us.
