What documents are necessary for a trust with limited assets?

The only document needed to set up a trust is the trust document, or, the Declaration of Trust. The trustee and all business carried on by the trustee must rely on the provisions in that trust document. It should always be drafted by an attorney who specializes in trust law in your jurisdiction since the trustee can only exercise the powers set forth in the trust document. An invalid trust can create problems that are costly to correct and must be addressed by a judge in a court of equity.
