Why should I resubmit proof that I already sent you years ago?
We always check whether we already have evidence documents for a reported participation. However, we always require evidence related to each individual participation. In the past, we were often sent extensive files that had to be processed manually at great expense. For economic reasons, this is no longer possible. In such cases, we may have to request specific, individual documents of proof again.
As a rule, we no longer have evidence that was submitted under the reporting form system up to 2010.
If you have any problems providing evidence, please contact the relevant specialist team.
