Joseph C. Portera


In the wake of the financial crisis, Joseph represented various financial institutions, including mortgage insurers, bond insurers, investment advisors, and financial guaranty insurers. While representing these clients, he was integrally involved in some of the nation’s first trials and arbitrations involving improperly and fraudulently underwritten loans.  The innovative work performed by Joseph and his colleagues in these matters included identifying and developing expert witnesses, creating new damage assessment methods and persuading courts to redress these claims. Other firms have looked to this model in similar cases. Today, Joseph continues in his innovative approach to complex legal issues by coupling creative legal strategies with highly developed, stand-up trial presentation skills.

Joseph’s exceptional ability to quickly grasp the workings of any industry and then distill and simplify the critical issues has enabled Joseph to develop a practice covering a broad range of industries. In the courtroom, he combines his industry knowledge with tested trial presentation skills to achieve success for his clients. Working with his Susman Godfrey colleagues, Joseph represents clients in a number of different fields, including investment management, mortgage insurance, energy, steel servicing and distribution, manufacturing, and fine art brokerage. Within these and other fields, Joseph has successfully handled diverse matters, including complex disputes involving structured financial products, product liability, intellectual property, contracts, insurance, fiduciary duties, and fraud.

Joseph is driven to provide his clients with the best possible results, and he expects his work to be judged on those results alone. He understands that the financial realities of litigation are a serious concern for both small businesses as well as large corporations. As a result, he encourages his clients to work with him to develop alternative billing options that will best meet their needs. This includes fixed fee, contingency fee, and other non-hourly fee arrangements that reward him for achieving positive results, and not merely for effort.
