Mark J. DePasquale

For over 25 years, Mark DePasquale has advocated for his clients in business disputes and civil appeals.

He practices in federal and state trial courts, and in Arizona's appellate courts. His clients range from individuals and small businesses to Fortune 500 Companies.

Mark's practice focuses on:

  • Contract Disputes  Representing both plaintiffs and defendants in a wide variety of contract disputes ranging from multi-million dollar, complex agreements involving sales of commodities, derivatives and swap agreements, to disputes involving sales of businesses, real estate and equipment (including breach of warranty and misrepresentation claims), and disputes over simple oral agreements.

  • Appeals  Advocating before the Arizona Court of Appeals and Arizona Supreme Court in a wide range of matters, ranging from business disputes to family law issues.

  • Securities Litigation  Representing parties in litigation involving claims of securities fraud, under both state and federal law

  • Shareholder Disputes and Corporate Divorce  Representing owners of closely held entities in disputes including disputes over bylaws and operating agreements, owner buyouts, wind-up provisions, allegations of breach of fiduciary duty, and minority shareholder rights

  • Antitrust Counseling  Advising clients on antitrust issues focusing on distribution issues and issues involving trade associations

Mark practiced for the first 10 years of his career with O’Connor Cavanagh Anderson Westover Killingsworth & Beshears – then the second largest law firm in Arizona – where he became a senior member. Since 1999, Mark has worked in a small or sole practice, combining his large-firm training and experience with the flexibility and lower overhead of a small firm.
