The key to protecting your Mercury accounts is making sure each one has a transfer mechanism in place—either a beneficiary designation or trust ownership. Without one, the account goes through probate, adding time, cost, and court involvement for your family.
Mercury has 10 product types, and the estate transfer rules differ across them. Some support Payable on Death (POD) designations, some can be retitled into a trust, and others will require probate if nothing is set up. Each is covered below.
- Individual: full name, date of birth, home address, and optionally Social Security number (used for identity verification only)
- Trust: the trust's legal name and Tax Identification Number
- Checking and savings balances are split EVENLY among all named beneficiaries — Mercury does not support custom percentages or contingent beneficiaries
Required Documents
- Trust name, date established, and tax ID (EIN or SSN)
Special Requirements
- POD is available on Mercury Personal checking and savings ONLY; it is not available on any business account
- Maximum of 5 individual beneficiaries OR 1 trust per account
- Shares are always equal. Custom percentages and contingent beneficiaries are not supported
- Per the Column N.A. Consumer Deposit Account Agreement, beneficiaries take only on the death of the LAST surviving account owner, and multiple surviving beneficiaries hold as joint tenants with right of survivorship
- If no designated beneficiary is living when the last surviving owner dies, the funds are paid to the legal representative of the last surviving account owner
- Trust accounts: beneficiaries must be listed during onboarding and cannot be changed self-serve afterward — changes go through personal@mercury.com and may require additional documentation
- Business account ownership is governed by the entity's formation documents and applicable state law, not by anything you can set in the Mercury dashboard
