There are many types of changes the credit union can make to your account, but there are also important protections for consumers. For example, there are limits on when the credit union can raise your interest rate and assess certain fees.
Also, the credit union generally must give you a written notice 45 days in advance of a change. You may have the right to reject the change, such as when the credit union wishes to raise many types of fees. If you reject the change, the credit union cannot apply it to your account.
Be sure to review your credit card or loan account agreement, which is the contract governing your credit card account. It provides information on changes that may occur to your account.
