There is nothing magical or mystical about a legal trust.
This is true, but there's still a reason that lawyers have to go to law school. If you don't form trusts every day, there's a lot of information to learn in order to do it properly. Moreover, while federal law doesn't apply to trusts, federal law does apply to NFA items, and you don't want your beneficiaries to be in trouble just because you didn't pay a few hundred dollars to have a lawyer do it right.
Now, I will admit that I am a lawyer, and that I have done a few gun trusts. (I am licensed in Kentucky, and so can only do them in Kentucky.) That may make you think that I'm just trying to protect my bottom line, but I honestly don't care if you write your own trust--I just want to see people do it correctly and not get in trouble.
Before I even graduated law school, I saw an estate go haywire because of an improperly drafted will and trust. My grandfather thought he was too smart to need a lawyer, and despite it being clear what he would have wanted done with his estate, that's not the way it ended up because he didn't draft his estate documents properly.
Add into the mix federal laws, and you could end up drafting a trust that allows you to get that SBR without paying a lawyer, but your kids end up dealing with humorless ATF agents after you die and your trust doesn't transfer the property legally.
The ATF isn't reviewing your trusts to make sure that nothing illegal will ever happen. If it's a basic, legal trust on its face, they'll approve it.
Just to give you one example, an online willmaking program will not prevent you from making yourself the grantor, the trustee AND the beneficiary. But if you do that, you haven't formed a legal trust. Then even if the ATF goes ahead and approves the tax stamp, because there's no legal trust, you're not "John Smith, trustee of the Smith Firearm Trust" in possession of a legal SBR. You're John Smith, regular guy, who doesn't personally have a tax stamp for the SBR he possesses. It's the difference between a good day at the range and a prison sentence.
I guess I just want people to understand that they're proceeding at their own risk if they form a trust without any legal advice. One trust is all you need to own as many NFA items as you want. When it costs you a $200 tax every time you want to buy a new toy, is it really that unreasonable to pay a lawyer $200 to draft you a trust the first time?
