Rebecca Attree M.A. (Cantab), Accredited Civil and Commercial and Workplace Mediator and Solicitor

I am an experienced mediator who specialises in helping parties resolve commercial and workplace disputes.

With over 35 years’ experience in assisting global businesses and individuals to resolve disputes and reach agreements, I am ranked as a Tier 3 Leading Mediator in Legal 500 UK 2023 (making me in the TOP 50 UK mediators), in Band 2 of the High Net Worth Guide of Chambers & Partners 2022 and consistently listed in Chambers & Partners Review of Mediators in the last 5 years.

My main sectors of expertise are mediating disputes relating to financial institutions, partnership, shareholder, commercial contracts, family office disputes, aviation, property, construction and workplace disputes. I am fully accredited to mediate in the UK, the US, and online, and have considerable experience of international disputes.

Mediation is an excellent way to resolve disputes without the costs of going to court or arbitration or formal management procedures such as grievance or disciplinary processes.

International Dispute Resolution and Mediation 7 September 2023 CIArb Western Counties. For more info click +

Mediation is highly effective dispute resolution method and endorsed by the English courts.
But does mediation work in an international conflict too?
How are disputes resolved in other countries?
What are the attitudes to mediation in different countries and cultures?
And most importantly what can we learn from each other?

CIArb Western Counties (in collaboration with DACB and BCCG) invites you to attend a virtual event. Our Chair and Vice Chair (Sean Gibbs and Kai von Pahlen) will interview distinguished mediators from different jurisdictions:

 England: Rebecca Attree
 France: Pierre Servan-Schreiber
 Germany: Ulrich Kremer

We will discuss their experiences in handling disputes in an ever increasingly international world, how businesses from different cultural backgrounds may come to the negotiation table with entirely different expectations and what lessons we can learn to resolve disputes in the most efficient way.

The event will be virtual and take place on 7 September from 2.30pm to 4pm.
If you would like to attend this virtual event, please email Kai von Pahlen at kvonpahlen@dacbeachcroft.com
