Mediation Style

Helen has been involved in numerous mediations, either representing one of the parties in a variety of commercial disputes, or acting as a neutral, on large negligence claims or complex multi-party claims to small contractual disputes. Some mediations have been emotional rollercoasters whereas others provided a sense of relief that the dispute could be resolved without recourse to the court or arbitration. Almost all of the mediations settled if not on the day then shortly after. 

She has always sought to help clients resolve disputes in the most economic and quickest timeframe possible and mediation can offer a unique opportunity to resolve the most fractious of disputes when negotiations have been unsuccessful or the parties have previously felt it was tactically inappropriate to make the first approach to settle. 

Mediation can be unsettling but may provide the resolution sought after by parties so that they can move on with their lives and businesses. For those who have never had experience of a mediation it is important to remember that nothing is binding until it is recorded in a written contract and that any information shared between the parties cannot be used in any litigation or arbitration.
