“When you live and breathe insurance regulation, you know how to spot what others miss—pathways that protect businesses today and unlock opportunity for tomorrow.”

Elizabeth Tosaris is a highly respected insurance lawyer, with nearly 35 years of experience guiding clients through complex regulatory frameworks. She represents insurers, HMOs, producers, and other insurance-adjacent businesses operating under the oversight of state departments of insurance.

With a national practice, Elizabeth handles everything from licensing, holding company filings, and approvals tied to mergers and acquisitions to compliance with the California Consumer Privacy Act and other evolving regulatory regimes. Her counsel spans rate filings, administrative challenges, privacy disclosures, and product development—always with an eye toward helping clients meet regulatory requirements while pursuing innovation and growth.

She regularly defends insurers in multi-state market conduct exams and enforcement actions brought by the California Department of Insurance. Her work also includes SIU-related matters, appearances at administrative hearings, and advising clients facing CID subpoenas, government data requests, and other inquiries.

Elizabeth’s reputation as a preeminent insurance lawyer is underscored by her recognition by Chambers USA, where she has been ranked annually since 2015.
