This discussion addresses how to formally notify a bank about changes in authorised signatories (like a new president and treasurer) for a society registered under the Karnataka Societies Act 1960. The consensus suggests that the election of new office bearers during the Annual General Meeting (AGM) is usually sufficient for the bank, provided the AGM minutes reflect this change. It's advisable to consult the bank directly and check the society's bye-laws for specific requirements regarding bank account operations.
