A trust in either real or personal property is enforceable only if there is written evidence of the trust's terms bearing the signature of the settlor or the settlor's authorized agent. A trust consisting of personal property, however, is enforceable if created by:
(1) a transfer of the trust property to a trustee who is neither settlor nor beneficiary if the transferor expresses simultaneously with or prior to the transfer the intention to create a trust; or
(2) a declaration in writing by the owner of property that the owner holds the property as trustee for another person or for the owner and another person as a beneficiary.
