An effective review begins with the transaction: what was agreed, what each party did, and where the disagreement arose. Contracts, amendments, invoices, performance records, and correspondence help establish that history. Our attorneys discuss the financial stakes, ongoing relationships, and practical effect of the available choices. Negotiation may offer a way to resolve disputed obligations, while some matters require a lawsuit or a response to an existing claim. This page focuses on disputes arising from commercial transactions; owner-management conflicts and broader civil matters may require a different analysis within the firm's business litigation practice. Related services include business and civil litigation and commercial debt collection.
