The 30 days immediately after a chiropractic license expires is called the "grace period." The Board allows a licensee to practice during those 30 days, but a penalty is added to your renewal payment. $125 is added for each week late, up to the maximum fine of $500.
If a licensee has not renewed by the end of the grace period, they are instructed to cease and desist practicing. If 12 months pass and the licensee still has not renewed, they will no longer have a license to practice. The person will need to reapply for licensure.
If a licensee does not cease and desist practice, they may be subject to disciplinary action by the Board.
