You should choose a Trustee in whom you have great confidence. In most cases, the Trustee is acting on his honor. On the other hand, the Beneficiaries can ask a court to remove the Trustee or order certain payments if the Trustee acts improperly. Either way, unless the Trustee and all Beneficiaries act together to break the Trust, they must dance to your music. If lack of court supervision is the greatest advantage in some cases, lack of supervision is the greatest disadvantage in others.
Most attorneys have horror stories of botched estate plans.
However, an estate plan with a trust can be botched as well as one without a trust. By setting up an estate plan with well-drafted trusts, it is possible to save hundreds of thousands of dollars, if the estate is that large. Even a very small estate generally saves much more than the cost of an estate plan in probate costs and attorney fees. More importantly, your Trustee will probably be someone who will miss you greatly. Setting up the estate to be administered as a Trust will save that person time and ease the stress of handling the estate.
