Idaho Admin. Code r. 34.05.06.305
If the trust is named in its organic document(s), its full legal name, as set forth in such document(s), is used. Such trusts are treated as organizations. If the trust is not so named, the name of the settlor is used. If a settlor is indicated to be an organization, the name is treated as an organization name. If the settlor is an individual, the name is treated as an individual name. A UCC document that uses a settlor's name should include other information provided by the filer to distinguish the debtor trust from other trusts having the same settlor and all financing statements filed against trusts or trustees acting with respect to property held in trust should indicate the nature of the debtor. If this is done in, or as part of, the name of the debtor, it will be entered as if it were a part of the name under Sections 407 and 408.
