No two business disputes are alike. For parties wishing to initiate a dispute: considerations such as contract terms, confidentiality, time constraints, preservation of future business, budget, and the importance of the legal principle at stake affect whether a particular dispute might be better solved through litigation, arbitration, or mediation.

For parties defending against a dispute: while certain of the decisions as to how and where a dispute will be resolved have already been made by the plaintiff, these considerations remain relevant to a party's defense against a case to the extent that any are changeable, were incorrectly invoked by the plaintiff, or remain available upon request of the defendant.

Mediation always remains a viable dispute-solving process for parties, in addition to, or instead of, litigation or arbitration. When parties are open to it, mediation has the power to be cost and time effective and to render results not achievable in an adjudicated proceeding.

Ms. Seniawski has represented parties in all stages of litigation in state and federal courts across the United States and in proceedings conducted under the rules of or before the American Arbitration Association, JAMS, the International Centre for Dispute Resolution, and various private arbitration forums.
