Are you talking about the same trust? Is there more than one trust? It is not uncommon for someone to be both trustee and a beneficiary, which is not in and of itself a problem. Sometimes people run into issues with interim distributions but so long as the terms of the trust are being followed a trustee is permitted to distribute funds to them self. Each beneficiary is entitled to information and an accounting to ensure that the terms are in fact being followed. You say that your mother does not have funds to defend herself= she is the trustee of the trust and so long as she is acting appropriately the trust should pay her legal fees. She clearly needs an attorney.

I agree with Attorney Zelinger. Your mother needs an attorney. The trust will pay for it.
