This depends on the nature of the dispute and your role in the dispute. For example, businesses defending against a commercial lawsuit typically hire a law firm or attorney on an hourly basis. Businesses hiring an attorney to bring a lawsuit against another business may hire the firm or attorney on a contingency basis, an hourly basis or a combination of both, depending on the nature of the case and the client’s goals. Diab Law Firm, PLLC, seeks to do right by every client and strives to accommodate your billing needs and resources. In the case of hourly billing, the firm provides a detailed accounting of billable hours upon the resolution of each case.
