How to name beneficiaries and fund a trust at Dimensional

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

There are two ways to keep your Dimensional investment 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.

Dimensional has 7 investment accounts with different estate transfer rules. Here is how beneficiary designations, trust ownership, and probate apply to each one.

What Dimensional's agreement says about beneficiaries1

A TOD designation supersedes the will's provisions for the account.1

Which accounts a trust can hold4

Dimensional ETFs are held through brokerage accounts, so trust retitling is handled by the brokerage firm, not by Dimensional.1

The funds accept a trust as a registered owner: the portfolios are available to U.S. domestic trusts with a U.S. address of record.2

Every investor must "complete and submit the necessary account registration forms in good order."2
