How to name beneficiaries and fund a trust at Mariner

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

Estate planning for your Mariner investment accounts starts with understanding how each one transfers at death. Beneficiary designations and trust retitling both bypass probate, but the right approach depends on the account type, your tax situation, and how much control you want over distributions.

Mariner has 10 product types, and the estate transfer rules differ across them. Some support Transfer on Death (TOD) designations, some can be retitled into a trust, and others pass through the estate if nothing is set up. Each is covered below.

  • Trust name, date established, trustees and tax identification number (for a trust beneficiary)

What Mariner says about beneficiaries and trusts

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

Which accounts take a beneficiary4

Investment account

Every designation is the custodian's, not Mariner's. Mariner coordinates; the custodian records and controls it.1

A TOD registration on a taxable account and a beneficiary designation on an IRA are different forms; updating one does not touch the other.1

IRA

An IRA beneficiary form and a taxable TOD registration are separate documents and do not update each other.1

Life insurance policy

Insurance beneficiaries are held by the issuing carrier, not by the custodian and not by Mariner.1

Annuity

Annuity beneficiaries are held by the issuing carrier, not by the custodian and not by Mariner.1

Who can be named1

A trust

A trust can be named as beneficiary. The custodian's form takes the exact trust name, the date it was established, the trustees, and the trust's tax identification number.1

A trust, IRAs

A trust can be named as beneficiary on the IRA form.1

How many beneficiaries, and how shares are split

All accounts

The custodian's form takes a percentage allocation for each beneficiary and whether they are a primary or contingent beneficiary.1

What Mariner's agreement says about beneficiaries1

When a designation takes effect

The change is not effective when Mariner receives it; it is effective when the custodian records it. Confirm it on the custodian's statement.1

Which accounts a trust can hold3

Investment account

Taxable, joint and separately managed accounts can be retitled into the trust on the custodian's paperwork, with Mariner coordinating. Mariner continues to manage the assets under the trustee's authority.1

IRA

An IRA cannot be owned by a trust. The trust is named on the IRA beneficiary form instead, if that is the plan.1

Trust account

The trust can have an individual trustee, with Mariner managing the assets, or Mariner Trust Company, LLC as trustee or co-trustee under its directed model, in which it handles administration and compliance while the Mariner advisor keeps the investment relationship.1

What Mariner says about trust accounts2

Whether a new account is opened

The trust account is opened at Schwab, Fidelity (National Financial Services) or Pershing; Mariner does not hold it. The retitling is complete when the custodian re-registers the account, which is what the statement shows.1

Successor trustees

Where Mariner Trust Company, LLC serves as trustee or co-trustee, a corporate trustee is already in place when the grantor dies.1
