If you are a trial lawyer, you will find yourself working all weekend the weekend before the case is set for trial. Then if the case is not reached or it gets postponed, you will work another weekend when it comes up again.
Attorneys in private practice may work weekends on a regular basis or some weekends just to catch up or accommodate clients who can only meet on weekends. If this is a field you are interested in pursuing I would say that it generally requires longer than usual work hours and involves a good deal of stress.
Volunteer attorneys do not answer criminal law questions. No matter where you live or work, there is a pro bono program that will be of interest to you and that needs your help. Visit The National Pro Bono Volunteer Opportunities Guide to find an organization near you.
Inactive attorneys who turn 70 do not have to pay the State Bar fee beginning in the next calendar year. An attorney may be placed on administrative inactive status (not eligible to practice law) for failure to comply with the MCLE requirement.
