1. Is it possible to remove all of the other trustees from your trust, purchase a new item, and re-add the trustees after the paperwork clears?
2. If so, how would I go about doing this?
3. Can I do it on my own, or does the attorney have to do it?
1. Yes
2. Write an amendment to your trust removing the other people (trustees/co-trustees) Submit that with your next Form 4. After approval you either write an amendment to add them back in, or simply shred the prior amendment.*
3. Depends. How comfortable are you with writing amendments, and do you want to risk having your Form 4 rejected or delayed for clarifications?
3a. Who wrote your trust?
