First Interstate offers 13 consumer accounts that interact with estate planning in distinct ways. Of those, 10 can name a trust as beneficiary or be retitled into a trust. Understanding the transfer methods available for each account type helps families keep assets out of probate and ensure they pass to the right people.

First Interstate lets account holders update beneficiary designations online, in branch, and by phone, typically taking 10-15 minutes. Trust funding is also available, allowing families to retitle accounts into the name of a revocable living trust.

There are two sides to estate planning at First Interstate: setting things up while you're alive, and the process survivors follow after a death.
