Funding letters: what banks actually want

A funding letter is a formal written request sent to a financial institution asking them to transfer an account or change a beneficiary designation so that a revocable living trust becomes the legal owner or recipient. It is the operational bridge between signing the trust document and the trust actually controlling anything. Without funding letters, the trust is signed but empty. The estate plan looks complete. It is not.

You probably already know funding matters. Fewer advisors know exactly what goes into the letters, what each type of institution requires, and why the details matter so much. If you have not read why most revocable trusts are never funded, that piece is the problem statement this one answers. This article covers the mechanics.

What a funding letter actually is

A funding letter is a business letter on the client's behalf, addressed to a specific department at a specific institution, requesting a specific change. It is not a legal document in the sense that a trust or will is. It is a formal instruction from the client (acting as trustee) 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: Uniform Trust Code § 1013, adopted in most states, lets a trustee give a third party a certification instead of the full trust instrument, and protects an institution that relies on it in good faith.

That sounds simple. It is not. The details vary by asset class, by institution, and by the specific action being requested. Getting any single detail wrong can delay the transfer by weeks.

Six categories, six different letters

Every asset in a household falls into one of six funding categories. Each category has different mechanics, different institution requirements, and different legal constraints. A funding workflow that treats them all the same will fail.

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 Certificate of Trust, and their own internal change-of-ownership form. Most banks process retitling requests through their Trust Operations department, not the branch. Processing takes three to seven business days at most major institutions. The account number usually stays the same.

Brokerage and investment accounts

Schwab, Fidelity, Vanguard, and every other brokerage have their own forms. 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. This distinction matters. A liquidation triggers capital gains. An in-kind transfer does not.

Most brokerages require a Medallion Signature Guarantee on their transfer forms. The letter should reference this so the client is not surprised when the brokerage asks for one. Some brokerages have dedicated POA and trust departments (Schwab and Fidelity both do). Routing the letter to the right department saves weeks.

Retirement accounts

IRAs, 401(k)s, 403(b)s, Roth IRAs. This is the category that trips up the most advisors, because the letter must explicitly not ask for retitling.

Retitling a retirement account into a trust triggers a deemed distribution of the entire balance. For a traditional IRA, that means the full balance becomes taxable income in one year. For a 401(k), same result plus a potential 10% early withdrawal penalty. The correct action is a beneficiary designation change, naming the trust as primary or contingent beneficiary. The account stays in the individual name. The downstream failure mode when those forms go stale is covered in beneficiary designation drift. The tax ID stays as the client's Social Security number. Only the beneficiary form changes.

For 401(k) and 403(b) plans, ERISA § 205 (29 U.S.C. § 1055) requires that a married participant name their spouse as primary beneficiary unless the spouse signs a written consent waiver. The letter should reference this and request the spousal consent form if applicable.

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 estate plans intentionally name a spouse as primary beneficiary with the trust as contingent. The advisor reviews each policy and decides whether a letter is warranted.

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.

For S-corps specifically, the trust must qualify as a grantor trust (automatic during the grantor's lifetime) or elect ESBT status within two years of the grantor's death to maintain the S-election. The funding letter surfaces this requirement so neither the advisor nor the client is blindsided later.

Safe deposit boxes

The most overlooked category. When a safe deposit box holder dies, the bank typically seals the box. Only an executor with letters testamentary (a court document) can access it. If the box is titled in the name of the trust, the successor trustee can access it without a court order. The funding letter requests that the bank update the box rental agreement to reflect the trust as holder and add all trustees as authorized accessors.

What institutions actually require

Every institution has its own process. But across thousands of funding interactions, the requirements fall into a consistent pattern.

• 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.

Processing times vary. Banks typically take three to seven business days. Brokerages take one to three weeks. Retirement custodians take one to four weeks. Insurance carriers take two to six weeks. Safe deposit box updates are usually same-day at the branch.

Why most advisors handle this wrong

Three failure modes.

First, the letters never get written. The trust is signed, the binder goes home with the client, and nobody generates the institution-specific letters that actually execute the funding. The advisor assumes the attorney handled it. The attorney assumes the advisor will. The client assumes someone professional is on it. This is the three-handoff problem described in detail in our previous post on trust funding failure.

Second, the letters are generic. A single form letter sent to every institution regardless of asset class. The retirement custodian receives a letter asking for retitling (wrong and dangerous). The brokerage receives a letter that does not mention in-kind transfer or Medallion Signature Guarantee (incomplete). The bank receives a letter without the Certificate of Trust (rejected). Generic letters create more work, not less, because every institution sends them back with questions.

Third, there is no tracking. Letters go out by mail. Some institutions respond in a week. Some take months. Some never respond at all because the letter went to the wrong department. Without a system that tracks which letters were sent, which were processed, and which are stuck, funding stalls where nobody can see it. The advisor does not know. The client does not know. The trust stays empty.

What a real funding workflow looks like

The funding workflow that actually works has five components.

Asset-class-specific templates. Each of the six categories 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. Trust Operations at Schwab is a different mailing address than Account Services at a local credit union. An institution database with verified department addresses eliminates the guesswork.

Batch generation. When a trust is finalized and the household asset inventory is complete, every funding letter for every asset should generate in one batch. The advisor reviews, edits if needed, and approves. The client downloads a packet.

Status tracking. Each letter has a lifecycle: drafted, approved, mailed, confirmed. The client marks each letter as mailed when they drop it in the mailbox. They upload proof of mailing (a receipt, a scan of the return receipt, a screenshot of the institution confirmation) to the encrypted vault. The advisor sees a dashboard showing exactly where each asset stands.

Automated follow-up. If a letter has been approved but not mailed after seven days, a gentle reminder goes to the client. This single automation closes the gap between "I'll get to it this weekend" and "it's been four months and I forgot."

The letter is the beginning, not the end

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.

A typical household has eight to fifteen assets that need funding action. Each one is a separate letter, a separate institution, a separate timeline, and a separate confirmation. If you build a real system for this work, or use a platform that already has one, you are the advisor who actually finishes the estate plan.

The rest are handing clients a signed trust document and hoping someone else does the work.

Hope is not a funding strategy.
