David Alderson, LL.B, LL.M, Q.Arb
Commercial Mediator

$565.00 per hour, plus facilities and taxes
Lower Rate if Disputes About $1 Million or Less

David Alderson seeks to be a resolver, an effective mediator, by being an interactive listener, a facilitator of communications and negotiation, and when the parties to a dispute require it, a neutral evaluator.

With over 40 years of practice as a lawyer in a very wide variety of civil litigation matters, including business, commercial, trade, property, distribution and franchise, technology, employment, reinsurance, trusts and estates, and marine disputes, both in local and international practices, David brings to the mediation a broad competence in facilitating the process, assisting parties to articulate their interests and to define the issues, and in subject matter neutral evaluation. He is equally at home in the context of complex, multi-party, and two-party single-issue disputes.

He is confident about the mediation process and considers that it provides the best prospect of resolving a dispute without resort to the expensive, time-consuming and disruptive process involved in traditional court-based litigation. David promotes principled negotiations so that the parties can assert and negotiate their interests, by an agreed process, on the path to a resolution acceptable to all parties. He can assist the parties to find viable options in their principled negotiations of the issues.

David will actively help parties get to the facts, and identify their respective interests, whether in a joint session or in caucus, and to overcome obstacles to a principled negotiation.
