Can a trustee move estate money into a personal account without the estate or co-trustee knowing?

Dear Sir,   Assuming this is an irrevocable trust (Settlor has died), Trustees are required to advise qualified beneficiaries of the trust and, upon request, to provide them copies w/i 60 days of the trustee(s) assuming trusteeship. Also, trustees are to provide annual accountings of trust transactions. A trustee's authority derives from the terms of the trust so it is possible for co-trustees to have independent authority but this is rare. Improper distribution of trust assets can serve as a basis for action for breach of trust.
