Revenue model

1. Contingency Fee Legal Services: Seeger Weiss operates on a contingency fee basis for most of its litigation. Clients never pay out-of-pocket for contingency services. The firm is only paid if the client wins their case. This aligns the firm's interests with their clients and allows individuals without financial resources to pursue complex litigation against well-funded corporations.
