For every performance of a play you need to ask permission and pay copyrights to the writer, the adapter and translator (until 70 years after their death). If you want to make an adaptation or translation of a play, you need permission as well.
On our Dutch website you can find the regulations regarding copyright and the procedure to follow when you want to perform a play. Do you need help with requesting the copyrights or do you have a question about it? Contact our colleagues from the Theaterbib. (firstname.lastname@example.org). We will try our best to help you in english if necessary.
