A trust company that administers a common trust fund may issue a certificate of participation for each participating account. A certificate of participation is not assignable and may not be issued in any form that purports to be negotiable or assignable. In any report or accounting required from the trust company by law, a statement that is signed and verified by one of its officers as to the existence, extent, and value of a participation in a common trust fund that it administers may be accepted as evidence of those facts by any court, trust clerk, or supervisory authority.
