About

Provided by Matheson LLP

Matheson’s Disputes and Investigations Group is market leading, representing both domestic and international clients.

The disputes we handle are often cross border in nature and precedent setting, requiring a collaborative and innovative approach, particularly where they are high-stakes, time-sensitive and carry significant reputational risk for our clients.

We believe our market leading expertise and the strength and depth of our team has contributed to Matheson being recognised as the ‘go to’ firm in Ireland for complex cross-border disputes. We have experience achieving successful outcomes for clients from all sectors including many regulated sectors.

Every deal or transaction carries with it the risk of a dispute and reputational management. Successful businesses require lawyers that can pre-empt the issues that may surface, take steps to minimise them and then react quickly and effectively when a dispute arises. We routinely assist our clients with pre-emptive advice on potentially contentious aspects of major corporate and financial transactions.

We play a critical role in the strategy of the dispute from the outset and minimise the cost and time involved in instructing external counsel. The partners in our Group are also leaders in the development of Alternative Dispute Resolution (ADR) and a number of our partners are accredited mediators.
