Can Family Members Use Firearms in My Gun Trust?
Written by Blake Stewart | Florida Bar No. 84716 | Admitted 2010 | Florida Bankruptcy & Estate Planning Attorney
Named co-trustees may lawfully possess and use NFA items held by the trust — without the registered owner being present. Here is who qualifies, what the ATF requires, and how to add family members correctly.
The Core Rule: Co-Trustees May Possess, Others May Not
Under federal law, only the registered owner of an NFA item may possess it. For an individual registrant, that means only you. For a gun trust, the registered owner is the trust itself — and every named co-trustee is treated as an authorized possessor of the trust's NFA items.
This is the single most practical advantage of a gun trust over individual ownership. A spouse, adult child, or other trusted co-trustee may take a suppressor to the range, use an SBR, or store NFA items at their home — all without you being present and all without violating federal law.
The risk under individual ownership:
A spouse who picks up a suppressor registered to their partner — without being a named co-trustee or completing an ATF transfer — is in unlawful possession of an NFA item. This is a federal felony under 26 U.S.C. § 5861(d), carrying up to 10 years in federal prison and a $250,000 fine. The fact that the item belongs to their spouse is not a defense.
Who Can Serve as a Co-Trustee
Any adult who is legally permitted to possess firearms under federal and Florida law may serve as a co-trustee. The person must not be a prohibited person under 18 U.S.C. § 922(g), which disqualifies individuals with:
- —A felony conviction
- —A domestic violence misdemeanor conviction
- —An active domestic violence restraining order
- —A mental health adjudication or involuntary commitment
- —Unlawful drug use or addiction
- —Other disqualifying status under federal law
Minor children cannot serve as co-trustees. They can be named as beneficiaries — designated to receive the firearms at your death — but they cannot lawfully possess NFA items.
Rule 41F and the Fingerprint/Photo Requirement
Under the 2016 ATF Final Rule (Rule 41F), every responsible person associated with a trust must submit fingerprints and passport-style photographs with each ATF Form 4 application for a new NFA transfer. A responsible person is generally any co-trustee who has the power to direct the management and policies of the trust with respect to the NFA items.
This means that if you have three co-trustees, all three must submit fingerprints and photographs for each new Form 4. This is a meaningful administrative consideration when deciding how many co-trustees to name — more co-trustees means more paperwork per transfer.
The fingerprint/photo requirement applies at the time of each new NFA transfer. It does not apply retroactively to NFA items already registered to the trust before a new co-trustee is added.

Frequently Asked Questions
Can my spouse use a suppressor registered to my gun trust?
Yes — if your spouse is named as a co-trustee in the gun trust. As a co-trustee, your spouse may possess and use any NFA item held by the trust without you being present. If your spouse is not a co-trustee, they may not lawfully possess the item when you are not present. This is one of the most common and consequential misunderstandings about individual NFA ownership: a spouse who picks up a suppressor registered to their partner, without being a named co-trustee or completing an ATF transfer, is in unlawful possession of an NFA item — a federal felony.
Who can be a co-trustee on a Florida gun trust?
Any responsible person who is legally permitted to possess firearms under federal and Florida law can serve as a co-trustee. This includes a spouse, adult children (18 or older), or other trusted individuals. The person must not be a prohibited person under 18 U.S.C. § 922(g) — meaning they cannot have a felony conviction, domestic violence misdemeanor conviction, active restraining order, or other disqualifying status.
What does Rule 41F require for co-trustees?
Under the 2016 ATF Final Rule (Rule 41F), every responsible person associated with a trust must submit fingerprints and passport-style photographs with each ATF Form 4 application. A responsible person is generally any individual who has the power to direct the management and policies of the trust with respect to the NFA items — which typically includes all co-trustees. This requirement applies at the time of each new NFA transfer, not retroactively to items already in the trust.
Can I add a family member as a co-trustee after the trust is created?
Yes. A revocable gun trust can be amended to add or remove co-trustees. Adding a new co-trustee does not require re-registering existing NFA items with the ATF — the new co-trustee simply becomes authorized to possess the items already held by the trust. However, the new co-trustee will need to submit fingerprints and photographs for any new NFA transfers made after they are added.
Can minor children be co-trustees?
No. Co-trustees must be adults (18 or older) who are legally permitted to possess firearms. Minor children can be named as beneficiaries — meaning they are designated to receive the firearms at your death — but they cannot serve as co-trustees and cannot lawfully possess NFA items. A well-drafted gun trust includes provisions addressing what happens if a beneficiary is a minor at the time of distribution.
What happens if a co-trustee becomes a prohibited person?
If a co-trustee becomes a prohibited person — due to a felony conviction, domestic violence conviction, or other disqualifying event — they must immediately cease possessing any firearms held by the trust. A well-drafted gun trust includes provisions addressing this situation and directing the trustee on how to handle it. This is one of the reasons why professional drafting matters: an online template is unlikely to include these provisions.
