Final answer:
Typically, a licensee has 20 to 30 days to request a hearing after being served with a notice of charges, though this can vary by jurisdiction.
Step-by-step explanation:
When a licensee is served with a notice of charges, the number of days they have to request a hearing may vary depending on the specific laws and regulations of the jurisdiction in question. Generally, in many jurisdictions, the licensee has typically 20 to 30 days to file a request for a hearing after being served with the notice. If a licensee does not respond within the specified time frame, they may forfeit their right to contest the charges and a default judgment could be entered against them.
