I think as long as you use the eForm process of the ATF, you’re probably doing OK, but that single-shot trust is inviting. It reduces the burden of a typical trust while allowing the addition of other people to the trust. Also, the trust is only for a single device, so paperwork is far less and the chances for mistakes nearly removed altogether.
I have a family trust for financial reasons but I went with the single-shot trust this time to try it out. I think I like it so far. Also, Silencer Shop made the trust paperwork free for me (cost was $25 for the trust, real cheap IMHO). I filled out the typical information online and they created the trust, eForm, paid the ATF, submitted, etc.
We’ll see if it results in any savings on the ATF processing time. So far, not too many people have said it does, so the jury is still out on that. The process is much simpler as SilencerShop also has fingerprint kiosks where you submit fingerprints instead of the Sheriff’s office.
I now have my attorney working on a Trust for my two Class III AR-15s, so that when I need to dispose of them, or die, they can safely and legally be transferred.
