kenny t, I don't know exactly, but public death record to me would play a big part. The ATF could easily get names of people who die and search their database. If a person does file under their own name, then they have to get fingerprinted and the CLEO in their county must sign their application. That may also be record catcher when the person passes away. The biggest thing is being legal after the death of the original purchaser. For all we know, there may not be a formal process, but the fine is pretty steep if caught and would you want your heirs to deal with that problem?
The other plus of a trust is that all persons listed as a trustee can be in legal possession of the NFA item on their own AND the trustees can be any person who can legally own a firearm. Trustees do not have to be family and they do not even have to live in the same state. All trustees do have to sign the trust, so its more feasible for them to be close by so you can get all their signatures.
We all know it happens everyday, someone whos up to a range with a suppressor and people start looking at it and wanting to try it out. If the person who owns the suppressor lets anyone else shoot it they just comitted a crime. Hell, if an owner of a suppressor at a range wants to go to the restroom, that person is by law supposed to bring it with him to the restroom or lock it up some place until the person returns. The person must be in possession at all times or the item must be locked up.
I'm not sure about VT, but here in LA suppressors are legal to hunt with now. Downfall is if you do hunt with a suppressor, your shooting subsonic loads so your traditional range is greatly reduced. Instead of shooting maybe 2800 fps, your now shooting under 1200 fps. You can still suppress supersonic loads, but you will still get the crack when the bullet breaks the sound barrier.
Edited to add: My trust was done via mail and I did not have to go in person. I did have to get it Notorized, so that was the person to person verification point. If you do go with a Trust, I would use a lawyer who has done NFA Trusts before. Not all lawyers do NFA Trusts.
www.silencershop.com has a search function for lawyers who setup NFA Trusts so you could check there. My laywer was a one time fee and he helps me ammend my trust (add or remove trustees) at no charge. Each time the trust is ammended, all trustees must resign the trust, so that is where it helps to keep the list of trustees small or the distance close.
Also on an NFA Trust, the Trust maintains a list of inventory. Typically these items are NFA items, but the items can be any serialized firearm which can be a form of estate planning for firearms.
