When, after four years or more, you have finished your manuscript, it is time to request the Graduation Formalities to start the defence procedure.

The PhD Regulations set out which criteria the dissertation has to meet. 

Consistent with these PhD Regulations, you must take steps in a formal procedure leading to the public defence of a PhD dissertation. 

These steps have to be taken by you and your supervisor in LUCRIS GSM. 
Please carefully follow this procedure overview and consult the manuals if you have any questions. 

Also, see the information about practical matters concerning the defence ceremony.
