Disputes and Investigations

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. We give our clients business-ready advice that enables them to approach a dispute, confident that we will guide them to the most commercial resolution.

Understanding your business and your objectives are key to our approach. Our size means we have the flexibility and depth of resources to handle large and complex litigation. We never forget that every client may have different needs and expectations. When necessary, we design and implement a bespoke service to meet our client’s requirements.

Our full service offering extends beyond traditional legal advice. Our Digital Services Group offers cost effective technological solutions and project management support for document intensive cases. Our resources facilitate the fast-tracking of the most complex commercial and cross-border disputes through Ireland’s Commercial Court.

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.

Our close working relationships with leading overseas law firms, experts in forensic investigations and other relevant disciplines, ensure that clients benefit from a seamless service.
