I wish I could find the thread on here between me and StalkingRhino discussing this on the old system. I had to re-do my whole trust since it was a property trust being converted by a lawyer into a gun trust and mailed it in with amendents via certified/signature mail. The consensus was that if they already have your Trust on file just do an amendment, notorize it (along with your new trustee's signature), and fax it in for confirmation. If you want to mail it....notorize, send certified/signature mail and ask for a return statement that they recieved it and what it contained.
