Trusts generally have one person designated as the principle trustee, who has the authority to amend the trust (add/remove trustees). If you were that principle person and had a trust with 5 trustees and the trust owns 20 items, you could theoretically remove the trustee that was causing issues. The remaining 4 trustees would have access to the items as they remain trustees within the trust. The removed (now former trustee) no longer has any right to any of the items held in the trust. It doesn’t matter from whose pocket the money came to purchase any of the items held in trust or anything else. Those items are owned by the trust until transferred to another trust/individual/legal entity (if an NFA item, this would require form4 and approved tax stamp).
