(1) Actions pending against the debtor as defendant on the date when the insolvency proceedings are opened may be joined by the insolvency administrator or continued by the plaintiff if they cover:
1. the separation of an object from the insolvency estate;
2. separate satisfaction; or
3. a debt incumbent on the estate.
(2) If the administrator acknowledges such claim immediately, the plaintiff may claim reimbursement of the costs incurred for such action only as an insolvency creditor.
