It's common practice for attorneys to charge an hourly rate. The hourly rate covers the time an attorney spends working on a client's case. However, hourly rates vary depending on location, attorney experience, and practice area. The lawyer then bills you for the extra work hours or may require you to replenish the down payment to continue working on the case.
Lawyers in major cities and urban areas tend to charge much more compared to attorneys in rural areas or small towns.
