Professional Liability Defense in Arizona

Protecting Business & Legal Professionals When It Matters Most

At Dyet & Hill, we provide experienced legal defense to business professionals, law firms, and other service providers facing claims of negligence, malpractice, and professional misconduct. These allegations can damage more than just reputations — they can threaten careers, businesses, and licensing.

With deep legal insight and strategic precision, we represent professionals and their insurers throughout Phoenix, Scottsdale, and across Arizona, guiding them through litigation with clarity and confidence.

When Advice, Judgment, or Services Are Challenged

Professional liability — sometimes referred to as errors & omissions (E&O) liability — arises when clients or third parties claim that a professional’s work fell below an acceptable standard of care, causing financial or personal harm.

We defend professionals in cases involving:

  • Alleged errors, omissions, or negligence in service delivery
  • Breach of fiduciary duty or conflict of interest
  • Malpractice claims against attorneys, accountants, consultants, etc.
  • Licensing board complaints or investigations
  • Failure to advise or failure to act

As Arizona-based CMV defense attorneys, we understand both federal transportation regulations and Arizona-specific legal challenges that impact your business.
