There are two ways to keep your HomeStreet 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 11 product types, HomeStreet 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 HomeStreet says about beneficiaries and trusts
Each section is HomeStreet's own statement, with the document it comes from numbered under Sources.
Which accounts take a beneficiary5
- Payable-on-death account
You keep full control during life. At the death of the last surviving owner the funds pass to the surviving named beneficiaries.1
- Joint account with survivorship
The account passes to the survivors on the death of any owner.1
- Joint account without survivorship
On a tenancy in common account, a deceased owner's share goes to that owner's estate, not to the co-owner.1
- Community property account
Married couples and registered domestic partners in Washington and California can hold one. Ownership during life and after death is determined by community property law and may be affected by a will.1
- IRA
A retirement account is never a payable-on-death deposit account. An IRA CD takes the IRA Beneficiary Designation form.2
Who can be named1
- A trust, IRAs
A trust can be named on the IRA Beneficiary Designation form.2
How many beneficiaries, and how shares are split
- Payable-on-death account
Absent written instructions, multiple beneficiaries share equally. The form takes allocation percentages where there is more than one beneficiary.1

What HomeStreet's agreement says about beneficiaries2
- When a designation takes effect
A designation is not effective until the bank has the signed documentation.2

Most former HomeStreet account numbers carried over unchanged. The bank says it notified the exceptions directly.2
Former HomeStreet products have new names: Free Checking and Student Checking became Essential Checking, Bank On Checking became Basic Checking, and Standard CDs became Personal CD.2

Which accounts a trust can hold2
- Trust account
Revocable and irrevocable trusts are both accepted on deposit accounts.2
The agreement recognizes Trust and Other Fiduciary Accounts, where legal title is held by a trustee, custodian, guardian, executor, administrator, or conservator under a separate instrument.1
- IRA
An IRA cannot be retitled to a trust. The trust is named on the IRA Beneficiary Designation form.2

What HomeStreet says about trust accounts5
- Whether a new account is opened
An existing deposit account can generally be retitled without closing and reopening it, as long as the same SSN or EIN applies.2
- Account numbers
The same account number is kept where the same tax ID applies.2
- Review of the trust document
For a Trust and Other Fiduciary Account the agreement says "You may be asked to provide a copy of relevant pages of the trust agreement and execute a trustee's certification of trust or other documents."1
- Who signs for the trust
The signers certify that they are authorized to manage the account.1
- Automatic payments and direct deposits
The old HomeStreet routing number still works. Use 121102036 when ordering new checks or deposit slips or setting up new ACH instructions.2
