Attorney fees refer to the charges that clients pay for legal services provided by a lawyer or law firm. These fees can vary widely based on factors such as the complexity of the case, the attorney's experience, and the region in which they practice. Common fee structures include hourly rates, flat fees, and contingency fees, where the attorney is paid a percentage of the settlement or award. Clients should discuss and understand the fee arrangement before hiring an attorney to avoid unexpected costs. It's also important to inquire about any additional expenses, such as court fees or costs for expert witnesses, which may not be included in the initial fee agreement.
