Final answer:
Without specific details on the jurisdiction or industry, it's not possible to provide the exact duration a change of ownership license is valid. Such temporary licenses vary in length and are subject to local business laws and regulation guides.
Step-by-step explanation:
A change of ownership license is a type of temporary licensing arrangement. Unfortunately, the question does not provide enough context to determine the exact duration this license is valid for, as it can vary by jurisdiction and specific industry regulations
. In many cases, a temporary license such as this one can last for several weeks or months. However, it is important to consult local business laws and regulation guides to get the precise duration for your area or specific situation. For instance, if this is for a liquor license or a business operating permit, the timeframe could be anywhere from a few days to several months, and it would be administered by local or state authorities that govern business practices and compliance. Without more context, it's not possible to give an exact number of days.
