There isn't anything specific in the regulation. There are some changes (related to legal cases, regulatory enforcement actions, etc.) that the MLO is required to update within 30 days. But as to other information, including the address that's the MLO's principal business location, the bank is required to have policies and procedures designed to review that information (frequency not stated) and compare it with its records. Theoretically, that can occur annually prior to the two-month renewal window.
It's up to the bank to decide how frequently those checks are done.
