Ex officio striking off of a company in Belgium
Recently, the Belgian government added two new grounds for the ex officio striking-off of a company. But what exactly does this entail, what are the (new) legal grounds for this and what are the consequences? You can read all about it in this article and find out when an ex officio striking-off can be revoked.
Ordinary creditors and preferential creditors what is the difference
When a company goes bankrupt, the trustee in bankruptcy uses its assets to pay creditors. The trustee blocks the accounts, sells equipment or machinery and collects any debts, and then pays the company's outstanding debts. But the order in which creditors are paid is not arbitrary. For this, the trustee in bankruptcy applies a legally strict order. Some creditors are therefore more likely to be paid (in full) than others. The decisive factor is whether a creditor is preferential or ordinary.
