How RIAs Can Serve as Co Trustees Without Triggering Surprise Audits
A trustee appointment can feel like the highest form of client trust. For a registered investment adviser, it can also create a custody problem overnight.
When a high-net-worth client asks an adviser, principal, or employee to serve as trustee, the request often comes from a good place. The client wants continuity. They trust the adviser’s judgment. They may believe the advisory team understands the family’s assets better than anyone else.
But under Rule 206(4)-2 of the Investment Advisers Act of 1940, better known as the Custody Rule, fiduciary authority over a trust can give the adviser legal access to client assets. That can mean deemed custody. If the role is structured poorly, it can trigger the annual independent surprise examination requirement, Form ADV-E filings, higher accounting costs, and more regulatory attention.
The good news is that an RIA may be able to serve in a carefully limited co-trustee role without triggering a surprise exam. The structure must be precise. The trust document, custodial account paperwork, written consents, and compliance records all need to tell the same story.
This article is for general informational purposes only and is not legal advice. RIAs should work with securities counsel and trust counsel before accepting any trustee or co-trustee appointment.
Why trustee appointments create custody by default
The Custody Rule does not focus only on whether an adviser physically holds stock certificates or client cash. The concept is broader.
An adviser has custody when it holds, directly or indirectly, client funds or securities, or has authority to obtain possession of them. That includes certain legal roles that give the adviser power over client assets.
A trustee usually has that power.
A standard trustee can often:
Withdraw trust funds
Transfer securities
Direct disbursements
Pay expenses
Move assets between accounts
Change custodial arrangements
Sign documents on behalf of the trust
If the adviser itself serves as trustee, custody is clear. If a supervised person of the adviser serves as trustee for an advisory client’s trust, the issue can also be imputed to the firm. The SEC staff has long viewed employee fiduciary authority as a custody concern for the adviser, even if the firm did not sign the trust document in its own name.
That is why a trustee appointment should never be treated as a courtesy title. In custody terms, it is not just a relationship status. It is legal authority.
What a surprise examination means for the firm
Once an RIA has custody, the firm must satisfy the Custody Rule unless an exemption applies. At a minimum, client funds and securities generally must be maintained with a qualified custodian, such as a bank, registered broker-dealer, futures commission merchant, or certain foreign financial institutions.
For many custody arrangements, the adviser must also undergo an annual surprise examination by an independent public accountant. The accountant must verify client funds and securities, then file Form ADV-E with the SEC.
That process can be expensive and intrusive. It also requires planning. The exam is “surprise” in the regulatory sense, so the firm cannot simply schedule it like an ordinary annual review.
The practical burden often includes:
Hiring an independent public accountant, often one registered with the PCAOB when required
Preparing books, records, account lists, and client information for testing
Coordinating with custodians
Responding to document requests
Updating Form ADV disclosures
Reviewing written policies and procedures
Managing deficiency findings if the accountant identifies issues
The cost can vary by firm size, account complexity, number of custodians, and condition of records. For many smaller and mid-sized RIAs, the annual cost and disruption are significant enough to change the economics of accepting a trustee role.
A trust appointment that creates a small amount of relationship goodwill can become a recurring compliance burden.
The co-trustee path is narrow
The key distinction is between unilateral authority and shared authority that the adviser cannot exercise alone.
A sole trustee usually has independent power over trust assets. That creates custody.
A co-trustee structure may avoid the surprise examination requirement if the adviser or supervised person cannot independently withdraw, transfer, or otherwise obtain possession of client funds or securities. The co-trustee must have meaningful control, and the documents must restrict the adviser’s authority in a way that cannot be bypassed.
The core idea is simple:
The adviser should not be able to move trust assets without the prior written consent or participation of an independent co-trustee.
That sounds straightforward, but the details matter. A trust agreement that names two co-trustees is not enough if either co-trustee can act alone. A custodial form that lets one trustee sign transfer instructions can undo careful trust drafting. A power to replace the co-trustee can also create problems if the adviser can remove the safeguard at will.
The safe structure must exist in the legal documents and the operating process.
The documents must block unilateral control
For an RIA or its supervised person to serve as co-trustee without triggering a surprise audit, the firm should focus first on the governing documents. The trust agreement, trustee acceptance, and custodial paperwork should be reviewed together.
The documents should make clear that the adviser-side co-trustee cannot act alone with respect to trust assets.
That usually means the trust agreement should require joint action for asset movement, including:
Withdrawals from trust accounts
Transfers of cash or securities
Disbursements to beneficiaries
Payments to third parties
Changes in account registration
Changes in custodians
Pledges or encumbrances of trust assets
The independent co-trustee should not be a figurehead. They need real authority and real responsibility. A family member, bank, trust company, attorney, accountant, or other fiduciary may serve in that role depending on the trust design, state law, and the client’s objectives. The independence analysis should be reviewed with counsel.
The custodial mandate is just as important as the trust instrument. If the trust says two signatures are required, but the custodian’s form allows one trustee to direct transfers, the firm has a weak control story.
The RIA should ask:
Does the custodian’s account agreement require dual authorization?
Are wire instructions blocked unless both co-trustees approve?
Can the adviser-side co-trustee change delivery instructions alone?
Can one trustee add or remove authorized signers?
Can one trustee move assets to another custodian?
Will the custodian send statements to the independent co-trustee?
If the paperwork is inconsistent, regulators will focus on practical authority, not the firm’s intent.
The independent co-trustee must remain a real check
A co-trustee structure works only if the independent co-trustee can actually stop an improper transfer.
That means the independent co-trustee should receive enough information to perform the role. At a minimum, they should receive account statements directly from the qualified custodian. They should also understand the dual-approval process and know that their approval is required before assets move.
The RIA should document the arrangement at the start. Good records may include:
The trust agreement and amendments
Written trustee acceptances
Custodial account agreements
Dual-authorization forms
Written instructions to the custodian
Evidence that statements go directly to the independent co-trustee or other required parties
Internal compliance approval before the appointment takes effect
Annual certifications that the arrangement has not changed
The firm should also watch for later changes. Trusts evolve. Co-trustees resign, beneficiaries request distributions, clients change custodians, and estate planning attorneys amend documents.
A structure that was sound on day one can become a custody issue later.
For example, assume an adviser employee serves with a client’s sibling as co-trustee. The trust and custodian require both signatures for transfers. Two years later, the sibling resigns, and the trust instrument allows the remaining trustee to act alone until a successor is appointed. If the adviser employee continues in that role without a replacement co-trustee, the custody analysis changes immediately.
The compliance team needs a trigger for that event.
Common drafting mistakes that create custody risk
Many custody problems come from small drafting choices. The adviser may believe it has limited authority, while the documents say something broader.
Here are common issues to catch before accepting the appointment.
Risky provision | Why it matters |
Either trustee may act independently | Gives the adviser-side co-trustee unilateral control over assets |
Co-trustees may delegate authority to one trustee | Allows the safeguard to be waived later |
The adviser-side co-trustee may remove and replace the independent co-trustee | Gives the adviser power to eliminate the check |
Custodial forms permit one trustee to sign | Creates practical access even if the trust requires joint action |
The trust allows the remaining trustee to act alone after resignation | Creates custody if the independent co-trustee leaves |
Broad emergency powers are not limited | May allow unilateral withdrawals or transfers |
Fee payment provisions are unclear | Can create separate custody concerns around fee deduction and client authorization |
The answer is not to add vague language saying the adviser “does not intend” to have custody. Regulators look at authority, not intent.
Better drafting uses direct restrictions. For example, the trust and custodial instructions can state that no withdrawal, transfer, disbursement, change of custodian, or change of authorized signers may occur without written approval from both co-trustees.
Counsel should tailor the language to the trust, state law, the custodian’s procedures, and the RIA’s compliance program.
The RIA’s policies should treat trustee roles as high risk
A firm should not let advisers, principals, or employees accept trustee roles informally. The compliance manual should require review and approval before anyone associated with the firm accepts appointment as trustee, co-trustee, executor, agent under power of attorney, or similar fiduciary for a client.
A strong internal process includes four steps.
Require pre-approval
No supervised person should accept a fiduciary role for a client without written approval from compliance. The request should identify the client, the legal role, the assets involved, related family relationships, compensation, and whether the client is an advisory client.
Review all governing documents
Compliance and counsel should review the trust agreement, amendments, custodial forms, signature authority, fee provisions, and any powers of attorney. The review should focus on actual authority over funds and securities.
Confirm custodian controls
The qualified custodian must be able to enforce the dual-approval requirement. If the custodian cannot code the account to require both co-trustee approvals, the paper restriction may not be enough.
Monitor annually
The firm should certify at least annually that the independent co-trustee still serves, the custodian still requires dual approval, statements still go to the right parties, and no document has changed.
This review should also tie back to Form ADV. If the firm has custody, or if it relies on a specific position to avoid surprise examination, disclosures should be consistent and current.
Consider alternatives before accepting any trustee role
Serving as co-trustee may be possible, but it is not always the best answer. Sometimes the cleaner choice is to help the client find an independent fiduciary and keep the RIA’s role limited to investment management.
Possible alternatives include:
Naming a bank or trust company as trustee
Naming a family member or trusted individual as trustee
Appointing the adviser as investment adviser to the trust, not trustee
Using a directed trust structure where state law permits it
Creating a trust protector or distribution adviser role with limited powers
Having the RIA provide reporting and investment support without legal control over assets
These options can preserve the adviser-client relationship without placing the firm inside the Custody Rule’s highest-risk zone.
A directed trust can be especially useful in some cases. The trustee handles custody, administration, tax reporting, and distributions, while the adviser manages investments under an advisory agreement. The exact design depends on state law and the client’s estate plan, but the separation of duties can reduce custody concerns.
The key is to define the adviser’s role around investment advice, not asset control.
A practical checklist before saying yes
Before an RIA or supervised person agrees to serve as co-trustee, the firm should be able to answer “yes” to these questions:
Has securities counsel reviewed the role under the Custody Rule?
Has trust counsel reviewed the governing law and fiduciary duties?
Does the trust require joint action for all asset movements?
Is the co-trustee truly independent of the adviser?
Does the custodian require dual authorization in practice?
Are account statements sent directly to the independent co-trustee or other required recipients?
Is the adviser-side co-trustee unable to remove the independent co-trustee unilaterally?
Is there a plan if the independent co-trustee resigns, dies, or becomes incapacitated?
Are the firm’s Form ADV disclosures accurate?
Has the role been approved under the firm’s compliance policies?
Will the arrangement be tested or certified at least annually?
If any answer is unclear, the firm should pause. The cost of restructuring before appointment is usually lower than fixing a custody issue after an exam.
The safest co-trustee role is limited, documented, and monitored
Clients often ask advisers to serve as trustees because they trust them. That trust matters, but it does not erase the Custody Rule.
A sole trustee role will usually create custody because the adviser has legal authority over client funds and securities. A co-trustee role can reduce that risk only when the adviser cannot act alone, the independent co-trustee has real control, and the custodian enforces the limitation.
The safest path is not a handshake or a side letter. It is a complete structure: trust language, custodial controls, compliance approval, direct statements, clear disclosures, and ongoing monitoring.
For RIAs, the best answer to a client’s trustee request may be “yes, but only with the right guardrails.”
