How to name beneficiaries and fund a trust at First Interstate

Beneficiaries are managed online, in branch or by phone. Trust paperwork is taken in branch, by phone or by mail

There are two ways to keep your First Interstate accounts out of probate: adding beneficiary designations and retitling eligible accounts into a revocable living trust. Which approach works best depends on the account type and your overall estate plan.

Across 14 product types, First Interstate accounts vary in how they transfer at death. The sections below walk through Payable on Death (POD) designations, trust funding options, and which products support each method.

What First Interstate says about beneficiaries and trusts

Each section is First Interstate's own statement, with the document it comes from numbered under Sources.

Which accounts take a beneficiary5

Account in one name

An individual account with no beneficiary designation is a Single-Party Account. With a POD designation, it becomes a Single-Party Account with POD.1

Joint account with survivorship

A joint account with no beneficiary is a Multi-Party Account with Right of Survivorship. Adding a POD beneficiary makes it a Multi-Party Account with Right of Survivorship and POD, and the POD beneficiaries take only after every owner has died.1

Joint account without survivorship

A Multi-Party Account without Right of Survivorship cannot be set up as an online designation. It is set up with a banker.1

IRA

An IRA beneficiary designation may require a separate beneficiary form.2

Trust account

A change to the beneficiary designation on a trust account may require updated trust documentation.2

Who can be named1

A trust

A trust can be named as a beneficiary. The designation may require a branch visit or a call to the Client Contact Center.2

A trust, IRAs

An IRA can name a trust as its beneficiary.2

How many beneficiaries, and how shares are split

Multiple surviving POD beneficiaries take the account in equal shares, with right of survivorship.3

What First Interstate's agreement says about beneficiaries3

A beneficiary who dies first

A POD beneficiary can withdraw only after everyone who created the account has died, and only if that beneficiary is then living.3

What the owner keeps while living

The people who created a Pay on Death or revocable trust account may change beneficiaries, change the account type and withdraw all or part of the funds at any time.3

Joint accounts

On a joint account the bank may disburse funds at the request of any co-owner regardless of contributions, "even if a co-owner is incapacitated, deceased, or whether the account is designated as having a right of survivorship."3
