We explained the process in four steps  here.

GVL exchanges information on repertoire used abroad in a standardised process. Your contribution registration in our Online Portal meine.gvl forms the basis for this data exchange with sister societies abroad so that we can establish claims on your behalf with them. In cases where you cannot find a production used abroad in meine.gvl you can notify us about this via e-mail to international@gvl.de. We also recommend to submit notifications for productions for which there are several entries in our database as the spelling of productions can differ from those abroad.

The countries and years for which we establish your entitlements depends on the  representation agreements in force and the scope of rights you granted us.  If you are unsure about this, please get in touch. You can access the respective form under Documents and Forms.
