The two routes in, and the threshold
A financial creditor, a lender, applies under Section 7 on proof of default. An operational creditor (a supplier, service provider or employee) must first serve a demand notice, and may apply under Section 9 only if the debt is undisputed.
The minimum default threshold is set by notification and has been raised substantially, which has taken smaller operational claims out of the IBC entirely. Where the amount falls below it, recovery has to run through the civil courts or the DRT instead.
What admission actually does
Admission is not a step in a negotiation. It is a transfer of control, and debtor companies frequently underestimate it.
Personal guarantees and directors
Insolvency of the company does not extinguish personal guarantees, and proceedings against personal guarantors have become a significant part of practice. Promoters who assume the corporate process protects them personally are frequently mistaken.
Directors also face potential liability for wrongful trading and for transactions that are preferential, undervalued, extortionate or fraudulent. Transactions in the period before admission are examined closely, which is why advice should be taken before assets are moved, not after.
