Third parties, i.e., persons who are not members of a Berlin University Alliance partner, may act as co-applicants, but without being entitled to funding. Anyone who has an employment contract with a partner institution of the Berlin University Alliance (defined by an employment contract with 50 percent of the working hours or more) is regarded as a member of a partner institution.

In addition, it is desired to name further external cooperation partners. It is possible to place orders externally within the framework of the allocation guidelines for budgetary funds of the respective partner institution. These are to be accounted for as full costs.
