In criminal defense cases, hourly fees might be applied for consultations and court appearances, while a retainer fee could be required to secure ongoing representation. For personal injury cases, contingency fees are often the norm, allowing clients to pursue claims without upfront costs. For instance, if a client wins a settlement of $100,000, the attorney may take a contingency fee of 33%, amounting to $33,000. These examples highlight how fee structures can significantly impact the financial aspects of legal representation.
