The question is: If I buy commercial rights, does the seller have to issue me any kind of license confirming the fact that I bought the commercial rights? Document, internet form, bridged agreement? That is, I pay 10 for voiceovers and get an audio file. And another 20 for commercial rights … and I’m not getting anything. How can I verify that I have commercial rights? Another question - what if, for example, I order content that is subsequently used for commercial purposes, but does not acquire commercial rights, what are the consequences in that case?
