Final answer:
Licensees who change their legal name must provide documentation of the change within 90 days.
Step-by-step explanation:
The correct answer is 90 days.
When a licensee changes their legal name, they are required to provide the committee with documentation of the change within 90 days. This ensures that the committee is aware of the name change and can update their records accordingly. It is important for licensees to promptly notify the committee to ensure that their information is accurate and up-to-date.
