Attorney fees (note that the use of the wor 'attorney' connotes lawyers broadly: solicitors and barristers) are the costs of legal representation that an attorney's client or a party to a lawsuit incurs. Attorney's fees are assessed in a number of ways, usually set by contract in advance of the representation, including by billable hours, flat fees, or contingent fees. Attorneys who voluntarily accept work on behalf of indigent clients often work pro bono.
