While there are many varieties of formal agreements for international collaborations, UC Santa Barbara employs two primary types: the MOU and the Collaboration Agreement. Appropriate approval and authorization is required for both. The memorandum of understanding (MOU) is a non-legally binding document that states a general desire to cooperate in certain broad areas. The MOU makes no promises on behalf of UC Santa Barbara, and states that both parties will enter into specific written agreements that define the nature and terms of proposed collaborations. The MOU format is recommended when partner institutions are either in the initial stages of collaborative discussions or when partners do not wish to commit to specific undertakings. The Collaboration Agreement specifies commitments for cooperation, exchanges, or other intellectual pursuits. Collaboration Agreements must be entered into with careful consideration, as they define commitments of resources, acceptance of obligations.
