I have not had to notarize when my Schedule A when I have added new items and BATFE has approved it every time.
I am just using my state as an example.
A trust also makes it easy if you want other to have access to your stuff when you aren't around.
Speaking of, that brings me to another question.
I know that the rules stipulate that I must be in control of the NFA weapon at all times.....so lets say I have a two month rotation at a hospital in Arkansas (Im in TX, so the SBR cant follow me there) what do I do? Can I leave it at home? Sure its in a safe, but what about the wife? Is she then in posession of the SBR illegaly? I searched various sites earlier but couldnt get a clear answer.
I would always recommend owning title-2 firearms individually if you can get a signature. The only time I would advocate doing otherwise is if you have multiple family members who you want to be able to shoot/use/have control of. And in that case I would go with an LLC or corporation where you can list those multiple people as members of the LLC or corporation. I own most of my title-2 stuff individually (have been very fortunate with CLEO signatures), but also have an LLC in Florida where my family owns a few MGs and SBRs so that my dad and brother may also take them to the range.
Someone else addressed it so....... File the form for the states where you know it is legal and will be traveling.
If it is locked up and cannot be accessed by anyone else while you are away AFAIK you are golden. If you have a trust and she is on it, then you are covered.
