Fiduciary succession planning is the discipline most employers skip until the day the CFO, HR director or founder who ran the 401(k) hands in a badge. The plan does not pause when a person leaves. Deposits still have to be remitted, claims still arrive, signatures are still required, and the departed person’s login may still open participant data. This post walks plan sponsors through what has to be reassigned, in what order, and what to prove afterward.
Why a departure is a fiduciary event, not an HR event
Most exit checklists cover laptops, badges and payroll. They rarely cover the plan. Yet the departing person may be a named trustee, a member of the plan committee, the signer on the Form 5500, the primary contact with the recordkeeper, or the only person who knows where plan records live. Fiduciary status follows the function, so leaving does not erase past exposure, and a vacancy does not erase future duties.
Where it goes wrong:
- The trust agreement still names a trustee who no longer works for you.
- No one is clearly the plan administrator, so notices and claims sit unanswered.
- The departed employee’s credentials remain active at the recordkeeper, payroll provider or custodian.
- Committee decisions stall because a quorum no longer exists under the charter.
- Bonding or insurance schedules still list the old person.
For a refresher on who holds which role, see the 3(16), 3(21), 3(38) and 402(a) roles explained and employees as retirement plan fiduciaries.
Step one: map every role the person actually held
Do not rely on a job title. Build a role map from the plan document, trust agreement, committee charter and your own recordkeeper paperwork.
1. Statutory and document roles
Identify whether the person was the named plan administrator, a named fiduciary, an individual trustee, or a committee member. Your plan document controls who holds each title, and the answer may differ from what everyone assumes. Confirm with your document provider.
2. Operational roles
List who approved distributions, signed loan paperwork, certified payroll data, reviewed the 5500 and answered participant escalations. These are the duties that fall through the cracks first.
3. Relationship roles
Note who owned the relationships with the recordkeeper, advisor, auditor, TPA and payroll provider, and who received their calls and notices.
4. Authorized signer roles
Record every vendor form, bank account and custodian profile where the person is an authorized signer or approver. Our guide to trustee duties and trust accounting covers why signature authority matters.
Step two: reassign fiduciary roles in writing
Reassignment is a documented act, not a hallway conversation. Settlor-level decisions, such as who serves on the committee or who is the plan’s named fiduciary, belong to the employer’s governing body and should be recorded that way.
1. Appoint the successor
Adopt a written resolution naming the replacement committee member, trustee or plan contact. Follow the appointment mechanics in your charter. If you lack a charter, see our overview of a benefit plan committee charter.
2. Check the quorum and voting rules
If the departure leaves the committee below its required number, decisions may be invalid until it is refilled. Resolve this before the next meeting, not at it.
3. Amend the trust and plan records if required
If an individual trustee is named in the trust agreement, an amendment or a successor-trustee provision may be needed. Do not assume the document handles this automatically.
4. Minute the transition
Record the decision, the effective timing and any interim coverage. Good committee meeting minutes are the proof an examiner will ask for.
Step three: update trustee signatures and authorities
A trust account is only as safe as the list of people who can move money in it.
1. Custodian and bank signature cards
Submit updated authorized-signer documentation to every custodian and bank holding plan assets, and request written confirmation that the departed signer is removed.
2. Recordkeeper authorizations
Many recordkeepers require a fresh certification of authorized plan officials. Send it promptly and keep the acknowledgment.
3. Corporate authority documents
If your recordkeeper relies on a corporate resolution or incumbency certificate, replace the old one so the new signer’s authority is traceable.
4. Pending transactions
Review anything in flight, including distributions, loans and corrections, so nothing is approved under a signature that no longer exists. See in-service distributions and rollovers in for the approval trail to preserve.
Step four: shut off portal access and secure the data
Access control is both a fiduciary and a cybersecurity issue. Participant data is a plan asset in practice, and the DOL has signaled that sponsors should manage who can reach it.
1. Inventory every system
Recordkeeper sponsor portal, payroll platform, TPA portal, custodian site, advisor reporting tools and any shared mailbox that receives plan notices.
2. Disable, then reassign
Deactivate the individual’s credentials the day the departure takes effect. Route shared mailbox alerts to a role-based address rather than another individual where possible.
3. Rotate shared credentials
If anyone shared a login, change it and confirm multi-factor settings. Our post on cybersecurity and participant data explains the expectations.
4. Preserve, do not delete
Archive the person’s plan files and email trail under your retention policy. The document retention checklist helps define what stays.
An eight-step transition self-check
- Role map completed from the plan document, trust, charter and vendor paperwork.
- Written appointment of each successor, recorded in minutes.
- Committee quorum confirmed under the charter.
- Trust and plan records reviewed for named individuals.
- Signature cards and authorized-official certifications updated.
- All portal and shared credentials disabled or rotated.
- Bonding and fiduciary insurance schedules reviewed. See fidelity bonds and fiduciary insurance.
- Vendors notified of new contacts, with written acknowledgment filed.
Where sponsors get hurt
- The silent single point of failure. One person held the knowledge, the logins and the relationships, and left with all three.
- Notices to a dead mailbox. Audit, 5500 and DOL correspondence routed to a former employee is still correspondence you were deemed to receive. See who signs Form 5500.
- Documents that disagree with practice. The plan names one administrator while someone else has been acting. Document and operations mismatches are a common finding.
- Interim gaps. Weeks without a decision-maker mean delayed remittances, unanswered claims and missed deadlines.
What you can delegate and what you cannot
You can delegate administration, but you cannot delegate being the employer. Choosing who serves as a fiduciary, adopting plan amendments and deciding plan design are settlor-level choices that stay with your governing body. Everything operational can move to a professional: the day-to-day administration, notices, filings, vendor coordination and access governance. A 3(16) administrator does that work, and it is how many sponsors make succession a non-event. Review 3(16) plan administration and the comparison of 3(16) versus TPA services. What stays with you is the employer-only data: payroll, census and eligibility facts that only your team can certify.
Take the person out of the structure
The durable fix is to stop making the plan depend on any one employee. When Admin316 serves as 3(16) administrator and accepts formal appointment as your plan’s ERISA 402(a) named fiduciary, which most providers decline, the named-fiduciary function sits with a firm rather than a job title. A resignation, retirement or reorganization no longer leaves your plan with an unnamed administrator. Learn more about 402(a) fiduciary services and the role of the ERISA 402(a) named fiduciary.
If a decision-maker is leaving or already gone, book a time with Admin316 and we will walk your role map, signatures and access before the gap becomes a finding.
