ORS 723.470: Checks drawn by agents presumed to be in authorized manner.

If a person who owns a share or deposit account subject to check authorizes another person as agent to draw checks against the account, the credit union, in the absence of written notice to the contrary, may presume that any check drawn by the agent in the manner authorized by the terms and conditions of the account, including checks drawn to the personal order of the agent, is drawn for a purpose authorized by the principal and within the scope of the authority conferred upon the agent.
