While a trust cannot do business, it can hold and lease business property. The documents are quite similar. One is a nonprofit trust, the other a legal trust that allows for unrelated beneficiaries and unspecified purposes. It is very general and can be used for many purposes. In Utah trusts are used for the more normal use of passing on property, estate and investments to heirs, but the law also allows holding trusts, voting trusts and tax trusts.
Most states have laws covering trusts and trustees.
Being a trustee is a fiduciary responsibility, governed by law and requires answering to the state in cases where there may be questionable conduct. Most people have an attorney draw up the trust documents and have the attorney hold them until their death or incapacity. In both cases, the attorney and the bank will have to be paid a fee for doing so. Another alternative is to fill out the trust documents for yourself or an elderly relative, making sure many people know about the trust. Set up a trust account in a bank and have a copy of the trust entered into the records of the local County Recorder's office, thereby making the trust a matter of public record.
