When must TREC be notified of an assumed name's usage or cessation?

The correct option indicates that TREC must be notified within 30 days when there is a usage or cessation of an assumed name. This requirement ensures that the commission maintains up-to-date records regarding the names under which real estate professionals operate, which is essential for consumer protection and regulatory compliance. Timely notification is important for transparency and allows the commission to effectively enforce regulations and investigate any issues that may arise related to the use of assumed names. By requiring notification within this specific timeframe, TREC can ensure that all parties involved in real estate transactions can accurately identify the entities they are dealing with, thereby promoting trust and clarity in the real estate market.
