Mandamus cases are distinct in nature as they do not involve seeking monetary compensation. Therefore, they cannot be handled on a contingency basis. Although hourly billing is an option for handling Mandamus cases, experienced litigators who are familiar with such cases can frequently estimate the time required. As a result, lawyers who handle Mandamus cases can typically offer clients a predetermined flat fee for their services, in addition to expenses incurred during the litigation process. However, in certain situations where the government opposes the case or the case is particularly complex, hourly billing may be necessary.

Currently and anecdotally, most cases seem to be able to be handled by an experienced attorney for less than $6,000 (including expenses).
