Biography

Christian Lassen is one of the nation’s leading life insurance attorneys and founder of The Lassen Law Firm—a powerhouse litigation firm focused exclusively on life insurance disputes. With 25 years of experience and hundreds of millions of dollars recovered, he is the go-to authority for policyholders and beneficiaries nationwide.

Mr. Lassen represents clients in all 50 states, handling complex life insurance disputes including denied claims, delayed payouts, beneficiary contests, policy lapse issues, accidental death denials, ERISA group claims, interpleader actions, military policy litigation (FEGLI, SGLI, VGLI, TSGLI), and allegations of fraud or misrepresentation. His practice is laser-focused on one goal: forcing life insurance companies to pay what they owe.

He was quoted in The Wall Street Journal on May 17, 2025, for his insight into life insurance payout delays, reinforcing his national reputation as a trusted leader in this field. He maintains a perfect 10.0 “Superb” rating on Avvo with over 1,700 peer endorsements and is a lifetime member of the Million Dollar Advocates Forum and the Multi-Million Dollar Advocates Forum—an honor awarded to fewer than 1% of U.S. attorneys.

Mr. Lassen does not waste time with adjusters. He crafts powerful legal briefs and delivers them directly to insurers’ legal departments—where real decisions are made. This aggressive, no-nonsense approach consistently results in swift and favorable outcomes. He personally manages every case and is known for his accessibility, responsiveness, and relentless pursuit of justice.

Licensed in New Jersey, Pennsylvania, and New York, Mr. Lassen handles life insurance cases nationwide. If your claim has been denied, delayed, or contested, Christian Lassen is the attorney who gets results.
