Oppenheimer has 16 investment accounts, each with different rules for what happens when the account holder dies. Of those, 12 can name a trust as beneficiary or be retitled into a trust. The right combination of beneficiary designations and trust ownership can keep the entire portfolio out of probate.
Beneficiary designations at Oppenheimer can be managed in branch, by mail, and by phone, typically taking same-visit signing with the Financial Professional; the registration appears on the account once processed by the branch.. Trust funding is also available, allowing families to retitle brokerage accounts into a trust.
Oppenheimer has documented procedures for both preparing accounts during your lifetime and handling claims when an account holder passes away.

Frequently asked questions
No. An IRA cannot be retitled into a trust while you are alive — it must stay in your individual name — and the same is true of your Individual 401(k), HSA, Coverdell ESA, and 529. Only your taxable Oppenheimer accounts (individual, joint, advisory, margin) can be retitled into the trust. You can name the trust as the IRA's BENEFICIARY, but read Oppenheimer's own warning first: its IRA Beneficiary Distribution Options guide (Retirement Services) treats a non-qualified trust as a non-person beneficiary, which can compress the entire IRA payout to five years. Naming individuals directly, or a properly drafted qualifying trust, generally preserves better distribution options.
