Stash and Sons v. New Hollard Credit Company - Superior Court - August 2, 2006

"[T]hose who deal with an unregistered party and accept the benefits of business transactions, having full knowledge of the party's true identify notwithstanding the fictious name, are estopped to deny the party's capacity to sue...If such a person knows with who he is dealing and is not deceived, he cannot assert the lack of capacity to sue under the Fictitious Names Act (FNA)," 54 Pa. C.S. 331.
The FNA says that an entity which has failed to register its fictitious name "shall not be permitted to maintain any action in a tribunal" in Pennsylvania and that, before such an entity can institute a lawsuit, it must register the name and pay a fine. The court held that this provision was penal in nature and should not be extended beyond the purposes for which it was enacted -- a) to protect people giving credit in reliance on the fictitious name and b) to establish the identities of the people operating the business. In this case, it was clear that all of this information was known, thus estopping the appellant/defendant from claiming harm and contesting the appellee/plaintiff's capacity to sue.
