As a rule, you are entitled to claim royalties within three years following the broadcast of your works. In other words, you must register and then declare your works with AGICOA Europe Brussels within three years until 31 December of the broadcasting year of your works in order to be entitled to payment.
For example, to benefit from royalties collected for a given broadcast year (e.g. 2022) your declaration should be made prior to the end of the third year following this broadcast year (e.g. before 31 December 2025).
