Mine is a revocable trust. I attempted to have one of the well known gun trust companies amend it and they told me it would just be easier to start a new one then to amend that one.
I consoulted a lawyer who told me a similar thing.
Perhaps they thought the potential for writing a new one from scratch would be worth the risk of loosing my business all together.
Please let me know what you find out and how you go about making the change.
The one time I dealt with a trust that I didn't draft, it was a complete... I can't think of a High Road word to use. It was bad.
Instead of amending that trust, I did a restatement for the fellow. While it may be an oversimplification, the easiest way to explain things is that the only thing you can't change about a revocable trust is the name. Otherwise, a restatement of the trust, which uses the same name, can more or less rewrite the entire trust. If you're going to make substantial changes, a restatement is the way to go. I don't know anything about your trust, but I imagine the lawyers you consulted didn't want to mess with someone else's trust language that might have been subpar. (And in the case of the online guy, he probably has a comprehensive product that he already knows works.)
Amendments are pretty simple. I'm not going to give legal advice to the OP or anyone else, but all that's required for an amendment, really, is to write down the changes you want to make, sign and notarize. Then keep the amendment along with the original trust. If court wants to read a trust, they read the original, then the amendments in the order in which they were made. (The caveat, as noted above, is that your amendment should also comply with any restrictions set out in the body of the trust.)
If you get to a point where you have a significant number of amendments that need to be read in order to understand the trust, that's the other time that a restatement can be helpful. A restatement can be used to incorporate all the amendments into a single document. (Once a trust is restated, the original trust documents and amendments prior to the restatement are not part of a court's future interpretation. It's like a "reset" button.)
OP, if you didn't consult a lawyer to draft your trust, then probably any "amendment" type form you come across on the internet won't steer you too far wrong, although you're running a risk any time you don't consult an expert. This is part of the reason (besides self-interest) that I recommend people find a reasonably-priced NFA trust attorney in their state--I include an amendment form with my trusts, but also provide free assistance with amendments any time in the future. They're not hard, but it also isn't something you want to screw up.
