How to move stock and brokerage accounts into a trust

Two different paths, and a signature guarantee most people have never heard of.

In short

Securities held in a brokerage account are usually moved by retitling the account itself, using the brokerage’s own trust transfer packet. Shares held directly with a company’s transfer agent are moved by a stock power sent to the transfer agent, which will normally require a medallion signature guarantee. Either way, the transfer is finished when the updated registration or a statement shows the position in the trust’s name.

First, find out how the shares are actually held

The same company’s stock can be held two entirely different ways, and the funding work is different for each. Ask this before filling in any form.

In a brokerage account, in street name
The brokerage holds the position for you. This is nearly all modern holdings. The transfer is a brokerage account retitling, and the brokerage handles the underlying positions.
Directly with the transfer agent
You are on the company’s own shareholder register, through its transfer agent, either as a book-entry position or with paper certificates. This is common with inherited holdings, employee stock, dividend reinvestment plans, and demutualized insurers.

A statement from a brokerage means the first. A statement or dividend check from a name like Computershare, Equiniti, or Broadridge means the second.

The brokerage path

  1. 01

    Ask for the trust transfer packet

    Every large brokerage has one. Some retitle the existing account, others open a new account in the trust’s name and transfer positions across. Ask which, because a new account number changes the paperwork downstream.

  2. 02

    Have the trust documents ready in the form they want

    Usually a certification of trust rather than the whole instrument, showing the trust name, its date, the trustee, and the trustee’s powers. Some brokerages still ask for the full document.

  3. 03

    Sign in both capacities

    The current owner signs to transfer, and the trustee signs to accept and to open. When they are the same person, the record should still show two signatures for two roles.

  4. 04

    Confirm the positions moved in kind

    Ask in writing whether anything will be sold. Cost basis should carry across, and a forced liquidation is a tax event nobody planned for.

  5. 05

    Check the next statement

    The account name on the statement is the proof. Brokerages sometimes keep the old number and change only the registration, which is fine, but then the name is the only thing that tells you.

The transfer agent path

Shares held directly are moved by instructing the transfer agent, and the transfer agent is protecting the company against a forged transfer. That is why this path is slower and stricter than the brokerage one.

  • A stock power or the agent’s own transfer form, signed exactly as the name appears on the register.
  • A medallion signature guarantee on that signature, in most cases.
  • The certificates themselves, if the shares are certificated. Send them insured and traceable, and never all in one envelope with the signed power.
  • Trust documentation: a certification of trust, and often the trustee’s identification.
  • A tax form for the new registration, since the trust’s taxpayer identification has to be on file.
Lost certificates are their own project

If a certificate cannot be found, the agent will require an affidavit of loss and normally a surety bond priced against the value of the shares. Start that before the rest of the funding, because it sets the schedule.

What a medallion signature guarantee is

A medallion guarantee is a stamp from a financial institution that stands behind two things: that the signature is genuine, and that the signer has the authority to make the transfer. The institution takes on liability when it stamps, which is why it will not do it for someone it does not know.

The programs are recognized under the SEC rule that lets transfer agents set standards for the guarantees they accept. Each stamp carries a coverage limit by dollar value, so a large transfer can be refused by an institution that would guarantee a small one.

  • Confirm the institution issues medallion guarantees, and at what coverage limit.
  • Book with the specific officer who can stamp, not with the branch.
  • Bring identification, the certificates or a current statement, and the trust documents.
  • Do not sign the stock power in advance. Sign it in front of the guarantor.
  • Check the new registration name against the trust instrument, letter for letter, before sending.

What proves it moved

Not the mailing receipt, and not the confirmation that a packet was received. The evidence is the registration itself.

Fidelity ····4417 — retitled to “Hartwell Family Trust, dated Mar 4, 2019”, confirmed by statement, Jun 3
Boeing common, 480 shares, Computershare — transfer submitted May 19, awaiting updated registration

The second line is the state most stock transfers live in for a few weeks. It is a normal state. What makes it a problem is leaving it unwatched, because a transfer agent that rejected the packet for a missing tax form will not call to say so.

Sources

This is an explanation of how a transaction works, not legal or tax advice. Termn is not a law firm, a bank, an escrow agent, or a money transmitter, and it never holds your money. What is right for your situation is a question for your own counsel, who decides it and drafts the documents that carry it.

Common questions

Do I have to sell anything to move it into a trust?
For a taxable brokerage account, normally no. Retitling the account moves the positions in place, without selling them, which is why retitling is the preferred path. A transfer that forces a liquidation is a tax event, so ask the brokerage explicitly whether positions move in kind.
Can a retirement account be retitled to a trust?
No. An IRA or a 401(k) is owned by an individual and retitling it to a trust would be treated as a distribution, with the tax that follows. Retirement accounts are handled through the beneficiary designation instead, and whether the trust should be named there is a question for counsel.
What is a medallion signature guarantee, and is it the same as a notary?
It is not. A notary confirms who signed. A medallion guarantee is a financial institution stamping its own liability behind the signature and the signer’s authority to transfer the securities, under a program its regulator recognizes. Notaries cannot issue one, and transfer agents generally will not accept a notarization in its place.
Where do I get a medallion signature guarantee?
From a bank, credit union, or brokerage that participates in a medallion program, and in practice from one where you already hold an account. Call ahead: many branches have only one officer who can stamp, guarantees are capped by dollar value, and you will need identification, the certificates or statement, and the trust documents.

Running one of these now?

Termn runs a stock transfer as its own tracked sequence: the packet, the signature in each capacity, the submission, and the transfer agent’s updated registration coming back.
