Will my current responsible broker/corporation be notified if I change to a different responsible broker/corporation?

Yes, if you change your responsible broker/corporation, a letter will be sent to your previous broker/corporation, informing them of the change.
Salespeople changing affiliation should advise their responsible broker of their intentions to leave and adhere to the provisions of their employment contracts when taking such action. Failure to comply with contractual agreements may be a matter for civil litigation.
