What Is ATF Rule 41F and Who Counts as a Responsible Person?
Written by Blake Stewart | Florida Bar No. 84716 | Admitted 2010 | Florida Bankruptcy & Estate Planning Attorney
The 2016 ATF Final Rule changed how NFA transfers to trusts work. It eliminated the CLEO sign-off requirement — and added a fingerprint and photo requirement for every responsible person in the trust. Here is what that means in practice.
What Rule 41F Changed
Before July 13, 2016, NFA transfers to trusts had a significant advantage over individual transfers: trusts were not required to obtain a CLEO (Chief Law Enforcement Officer) signature. Individual applicants needed a CLEO sign-off — and many CLEOs refused to sign, effectively blocking NFA transfers in those jurisdictions.
Rule 41F leveled the field — but not entirely in the way trust owners hoped. The rule:
- —Eliminated the CLEO sign-off requirement for individual transfers (replaced with notification only)
- —Added a fingerprint and photograph requirement for every responsible person in a trust or legal entity
- —Required a completed ATF Form 5320.23 (Responsible Person Questionnaire) for each responsible person per transfer
The net result: trusts still offer meaningful advantages over individual ownership — particularly for shared possession and succession planning — but the administrative burden per transfer increased for trusts with multiple co-trustees.
Who Is a Responsible Person?
Under Rule 41F, a responsible person is any individual who has the power or authority to receive, possess, ship, transport, deliver, transfer, or otherwise dispose of a firearm for, or on behalf of, the trust. In practice, this means:
Co-trustees
Always responsible persons — they have full management authority over trust assets
Certain beneficiaries
Only if they have an immediate right to possess trust items under the trust document
Successor trustees
Generally not responsible persons until they assume the trustee role
Contingent beneficiaries
Generally not responsible persons — their interest is not yet vested
How the trust document defines trustee authority and beneficiary rights directly affects who must submit fingerprints and photographs. This is one of the most important drafting considerations in a gun trust — and one reason why professional drafting matters.
What Each Responsible Person Must Submit
Fingerprint cards
Two completed FD-258 fingerprint cards. These can be completed at a local law enforcement agency, a licensed fingerprinting service, or an FFL dealer.
Passport-style photographs
Two recent passport-style photographs (2" × 2"), taken within the past year.
ATF Form 5320.23
A completed Responsible Person Questionnaire for each responsible person, submitted with the Form 4 application.
Frequently Asked Questions
What is ATF Rule 41F?
ATF Rule 41F is the informal name for the ATF's 2016 Final Rule (81 Fed. Reg. 2658), which took effect July 13, 2016. The rule changed the requirements for NFA transfers to trusts and legal entities. Most significantly, it eliminated the CLEO (Chief Law Enforcement Officer) sign-off requirement that previously applied to individual NFA transfers — but it added a new requirement: every responsible person associated with a trust must submit fingerprints and passport-style photographs with each ATF Form 4 application.
Who counts as a responsible person in a gun trust?
Under Rule 41F, a responsible person is any individual who has the power or authority to receive, possess, ship, transport, deliver, transfer, or otherwise dispose of a firearm for, or on behalf of, the trust. In practice, this means all co-trustees — and potentially certain beneficiaries who have immediate rights to the trust's NFA items. The ATF's definition is broad enough that trust drafting decisions about who holds what authority directly affect who must submit fingerprints and photographs.
What does Rule 41F require for each NFA transfer?
For each ATF Form 4 application, every responsible person must submit: (1) two completed fingerprint cards (FD-258); (2) two passport-style photographs; and (3) a completed ATF Form 5320.23 (Responsible Person Questionnaire). These must be submitted along with the Form 4, the $200 tax stamp payment, and a copy of the trust document.
Does Rule 41F apply to NFA items already in my trust?
No. Rule 41F applies at the time of each new NFA transfer to the trust. It does not retroactively require fingerprints and photographs for NFA items already registered to the trust before the rule took effect or before a new co-trustee was added. Adding a new co-trustee to an existing trust does not require re-registering existing NFA items.
Did Rule 41F eliminate the CLEO sign-off requirement?
Yes — for trusts and legal entities. Before Rule 41F, individual NFA applicants were required to obtain a signature from their Chief Law Enforcement Officer (CLEO) — typically the local sheriff or police chief. Many CLEOs refused to sign, effectively blocking NFA transfers in some jurisdictions. Rule 41F replaced the CLEO sign-off requirement with a CLEO notification requirement: the applicant must send a copy of the Form 4 to the CLEO, but the CLEO's approval is no longer required. This change applies to both individual and trust transfers.
How does Rule 41F affect how many co-trustees I should name?
Each additional co-trustee adds fingerprint and photograph submissions to every future NFA transfer. For a collector who regularly acquires new NFA items, naming many co-trustees increases the administrative burden per transfer. Most clients balance the practical benefit of shared possession against the paperwork cost of additional responsible persons. There is no universally correct number — it depends on your acquisition plans and who genuinely needs lawful access to the items.
