There are two ways of being reimbursed for going abroad (or just leaving your University site for academic reasons, as following a seminar or participating in a conference):
– using the 10%, that is the amount given to every student (either with or without a scholarship), mandatory form the second year of the Doctorate (called 10%, because it corresponds to 10% of the total amount of a scholarship). You have to ask for “Missione” and use your money and be reimbursed with the evidence of the travel (tickets, and bills).
– or asking for an increase in the scholarship (if you have one). To have the increase of the scholarship you have to ask to the University that provides your scholarship and have a letter of authorisation written by the Coordinator of the Doctorate..

Each University has its own procedures.  The University of Torino has an online program where you can make a request (once you have an agreement for going abroad) and you should ask the coordinator to give an approval on the online system. With the other universities, you have to send a request to the offices, with a letter of the coordinator that approves your request.
Basically, you need
(1) the exact dates of the period of staying abroad;
(2) a letter of invitation from the host institution with the same dates;
(3) an approval from the coordinator of the doctorate;
(4) an email confirming your arrival.

(5) At the end of the period abroad, you need to have a signed letter confirming the date of leaving; the letter must be given to the offices no later than 15 days after the end of the period abroad

You don’t need a formal co-tutorship to study abroad; often an agreement with a teacher or paying the fees of the foreign University is enough to spend a period of research abroad (a good doctoral degree in Europe is enough to participate to post-PhD scholarships: what counts are publications and curriculum). However, the occasion to have institutional agreement among Universities in Europe may help the diffusion of new methods and exchanges in teaching and learning. A co-tutorship with a University abroad requires a procedure to be organised by the administrative University  (Turin for cycles 29-32, Genoa for cycles 33-35) in the first year of the doctorate.
