Missouri Revised Statutes Title XXXI. Trusts and Estates of Decedents and Persons Under Disability § 456.4-407. Evidence of oral trust

1. Except as provided in subsection 2 of this section, a trust need not be evidenced by a trust instrument, but the creation of an oral trust and its terms may be established only by clear and convincing evidence.

2. Other than for a conveyance by which a trust may arise or result by the implication or construction of law, all declarations or creations of trust of any lands, tenements or hereditaments shall be manifested and proved by some writing signed by the party who is, or shall be, by law, enabled to declare such trusts, or by the party's last will, in writing, or else they shall be void.
