Funding letters: what banks actually want

A funding letter asks an institution to begin or process a specified change. It may request retitling information or a beneficiary-change form. The letter itself does not transfer ownership, change a designation or prove that a trust is funded. The useful record is the institution’s confirmation after its requirements have been met.

This piece covers what goes into the letters and what each type of institution requires. For why funding stalls after the signing in the first place, see why most revocable trusts are never funded.

What a funding letter is

A funding letter is a business letter from the client, addressed to a specific department at a specific institution, requesting a specific change. It is not a legal instrument in the sense that a trust or will is. It is a formal instruction from the client, signing as trustee where the trust is the new owner, to the institution that holds the asset.

The letter identifies the client, the trust, the account, and the requested action. It references the enclosed Certificate of Trust (a summary of the trust's key provisions that institutions accept in place of the full trust document). It provides signature lines and contact information so the institution can verify and process the request. The certification is a statutory instrument: section 1013 of the Uniform Trust Code, which most states have enacted in some form, lets a trustee furnish a certification instead of the trust instrument, requires it to state that the trust has not been revoked, modified, or amended in a way that would make its statements incorrect, and provides that a person who acts in reliance on it without knowledge that its representations are incorrect is not liable for doing so.

The details vary by asset class, by institution, and by the specific action being requested, and getting one wrong can delay the transfer by weeks.

Letters by asset category

Bancroft drafts letters in five categories from the household’s asset inventory: bank accounts, brokerage accounts, retirement beneficiary changes, life insurance beneficiary changes, and business interest assignments. They do not cover every asset or replace the institution’s requirements. Match the request to the asset and the plan the household chose.

Bank accounts

Checking, savings, CDs, credit union accounts. Two paths: retitle the account into the trust name (the institution closes the individual account and reopens it titled to the trustee), or add a payable-on-death designation naming the trust as beneficiary. Retitling gives the trustee immediate access upon incapacity. POD keeps the account in the individual name during life but transfers at death without probate.

What the bank wants: the funding letter, a certification of trust, and its own change-of-ownership form. Many banks process retitling through a trust operations department rather than the branch, so ask where the request should go before it is mailed. Whether the account number changes depends on the bank.

Brokerage and investment accounts

Every brokerage has its own forms; what Fidelity, Schwab and Vanguard each ask for is set out institution by institution. The funding letter for a brokerage does not execute the transfer itself. It requests that the brokerage send their Trust Account Application packet and transfer authorization forms. The letter explicitly asks for an in-kind transfer (preserving cost basis) rather than a liquidation and re-purchase, because a liquidation can realize capital gains and an in-kind transfer does not.

Brokerages often require a Medallion Signature Guarantee on their transfer forms. The letter should mention it so the client is not surprised when the brokerage asks for one. Ask whether the brokerage has a trust or estate services department, and address the letter there.

Retirement accounts

IRAs, 401(k)s, 403(b)s, Roth IRAs. The letter for these accounts must not ask for retitling.

It asks for the custodian’s beneficiary designation process instead. Transferring or distributing retirement assets can have significant tax consequences. Have the estate attorney and tax advisor confirm the intended designation before submitting it.

For 401(k) and 403(b) plans, ERISA section 205 (29 U.S.C. § 1055) generally requires a married participant’s spouse to consent in writing, witnessed by a plan representative or a notary, before anyone else is named as primary beneficiary. The letter asks the plan to include its spousal consent form where the participant is married.

Life insurance

Life insurance funding letters request a beneficiary designation change form from the carrier. They do not request a change of policy ownership (though that is sometimes appropriate for ILIT planning, it is a separate conversation). The letter specifies whether the trust should be primary or contingent beneficiary, and requests any required notarization or witnessing instructions.

Not every policy needs a funding letter. Many plans name a spouse as primary beneficiary with the trust as contingent. The household records each policy’s current designation in its inventory, and a letter goes out only where the current designation differs from the action the household chose.

Business interests

LLC membership interests, S-corp shares, partnership interests. This is the most complex category. The funding letter is a cover memo accompanying an Assignment of Interest document. Before the letter is sent, the client must verify that the operating agreement, shareholder agreement, or partnership agreement does not restrict transfers or require consent from other owners.

S-corporation shares require special attention to eligible trust shareholders and election deadlines. The applicable route depends on the trust and circumstances. Have the business attorney and tax advisor resolve eligibility and timing before any assignment; a cover letter cannot make that determination.

Safe deposit boxes are handled outside the letter categories. Ask the bank about access, ownership, and authorized signers for the box; the rules after death and the documents needed for access vary, and a change to the lease does not transfer ownership of the contents.

What institutions require

Each institution sets its own documentation and processing requirements. Confirm the current checklist and destination before sending the request. The following are common items to ask about:

• A formal letter on the client's behalf identifying the account, the trust, and the requested action.
• A Certificate of Trust (not the full trust document). The certificate summarizes the trust name, date, trustees, and relevant powers without disclosing beneficiaries or distribution terms.
• The institution's own forms. Banks and brokerages almost always require their own paperwork in addition to the funding letter. The letter requests those forms.
• Signature and contact information. The letter must be signed by the client (acting as trustee) with full contact details so the institution can verify.
• For brokerage retitling: a Medallion Signature Guarantee, obtainable at a bank, credit union, or broker-dealer.
• For retirement accounts: the institution's beneficiary designation change form, not a retitling request.
• For business interests: the Assignment of Interest document, signed separately from the letter.

Ask the receiving department for an expected processing time and a reference number. Set a follow-up date, record requests for additional information and keep the final confirmation. Avoid promising a completion date the institution has not confirmed.

Where funding requests go wrong

First, a request may never be prepared. The signing meeting ends, and each person assumes someone else will handle the institution paperwork. Assign the next action before the household leaves.

Second, the letters are generic: one form letter goes to every institution regardless of asset class. The retirement custodian receives a letter asking for retitling, the request the letter must not make. The brokerage receives a letter that does not mention an in-kind transfer or a Medallion Signature Guarantee. The bank receives a letter without the Certificate of Trust and rejects it. Each of these requests comes back with questions.

Third, there is no tracking. Letters go out by mail. Some institutions respond in a week, some take months, and some never respond at all because the letter went to the wrong department. Without a record of which letters were sent, which were processed and which are stuck, neither the advisor nor the client can see where funding has stalled.

What a real funding workflow looks like

Asset-class-specific templates. Each category gets its own letter with the correct language, the correct enclosures, and the correct department routing. A bank retitling letter is structurally different from a retirement beneficiary letter. They should not share a template.

Institution-aware addressing. The letter should route to the correct department at the correct address, which differs from a large custodian’s trust operations unit to a local credit union’s account services desk. A record of verified department addresses settles where each letter goes.

Batch generation. When the household’s trust document is in place and an asset in the inventory is marked for the trust, its funding letter should be drafted without anyone retyping the account details. The advisor or the household approves the drafts, and the household downloads a packet with the letters and a certification of trust.

Status tracking. Each letter has a lifecycle: drafted, approved, mailed, confirmed. The household marks each letter as mailed and uploads its proof to the encrypted vault, and the institution’s own confirmation is the proof to ask for, because a mailing receipt shows only that a request was sent. The advisor sees where each letter stands.

Automated follow-up. If a letter has been approved but not mailed after seven days, a reminder goes to the household, at most once a week, and the advisor is emailed when a letter is marked mailed and when proof is uploaded.

After the letter goes out

Writing the funding letter takes minutes. Getting the institution to process it takes weeks. Confirming the processing takes follow-up. And then the next account needs the same treatment, and the one after that.

Each asset is a separate letter, a separate institution, a separate timeline, and a separate confirmation, and the household’s list is only finished when the last confirmation is on file.
