ERISA and disability insurance claims handling and litigation

Our law firm provides persistent, results-oriented representation that ensures clients receive fair payment for their disability, health and life insurance claims. Most employer-sponsored benefits are governed by the Employee Retirement Income Security Act (ERISA). Many professionals purchase private insurance policies, which are also known as individual disability insurance policies. Our knowledge of the laws impacting your claim is vast. We are on your side to explain your rights and champion your interests in every aspect of a claim:

When payment is delayed or denied, our attorneys appeal adverse benefit decisions and, if necessary, commence lawsuits to obtain appropriate benefits for you. We also help with 401k benefits under ERISA.

Insurance claims coverage and litigation

Our firm is a powerful advocate in your effort to obtain benefits under an insurance policy. We help when your insurance company denies your claim by appealing your case. In some instances, an insurer acts inappropriately in handling your claim and can be sued for bad faith practices.

Personal injury

Our Nassau County injury attorneys help clients dealing with the physical, financial and emotional effects of injuries sustained as a result of negligence. We handle cases from beginning to end — from filing claims within the statute of limitations and investigating negligence to settlement negotiations and advocating for clients in trial, when necessary. We have experience with personal injury cases involving the following situations:

Criminal law and white-collar defense

Our attorneys vigorously defend individuals and corporations suspected or accused of illegal conduct. As former prosecutors, we anticipate the tactics used by state and federal authorities and devise defense strategies that, in most cases, minimize consequences to our clients. Our comprehensive criminal defense practice encompasses felonies and misdemeanors, with particular emphasis on white-collar crime.

Business and commercial litigation

At Sepe & O'Mahony, PLLC our extensive business services range from corporate formation, contracts and counseling to superb advocacy in complex commercial litigation. Our attorneys share our clients’ priorities, and, consequently, are ever mindful of their daily operation, strategic goals, and bottom line.

Legal malpractice and professional liability

Our attorneys possess a thorough understanding of the standards by which lawyers and law firms must operate. We help attorneys abide by those standards and avoid the risk of malpractice claims. We also advocate for professionals accused of misconduct, helping to secure coverage for claims under their professional liability policies, and defending them where coverage has been denied while pursuing coverage through declaratory judgment actions. Our practice also includes the representation of plaintiffs when a law firm's conduct results in financial harm to its clients.
