Check your CD’s documentation, but typically, you’ll have a grace period at CD maturity. You can decide whether to roll over your CD, make changes to your CD account, or withdraw your funds. However, if you indicated that you wanted your CD to automatically rollover, this may happen without any further input from you. In addition, if you don’t respond to your bank’s notice about a CD for which you didn’t indicate renewal, the bank may automatically cancel your CD and transfer funds back to you.
