What to do now
- Do not deliver on credit any more without an agreement with the curator.
- Gather your documents: invoices, purchase orders, contract, delivery notes and reminders.
- File your proof of claim in RegSol (regsol.be), yourself with eID or itsme, or through your lawyer. State principal, interest and costs separately, and any preferential right you hold.
- Delivered under retention of title? Reclaim your goods before the first report on the verification of claims.
- Ask your accountant about the VAT on the unpaid invoices: in a bankruptcy it can be recovered under conditions.
- Follow the file in RegSol: the verification report (admitted or disputed) and the curator's reports appear there.
The deadlines above come from the publication of the judgment. Check them in RegSol before you file anything; a passed deadline no longer applies.
