Section 66(1) makes inability to pay a requirement for opening proceedings. Subsection 2 provides that it is presumed in particular where the debtor has ceased payments. Creditors need not already be pressing for payment. Paying some creditors does not by itself establish that the debtor remains able to pay.
The statement that the debtor has not paid is therefore insufficient, as is a collection of unconfirmed market rumours. Concrete facts need a date and source. They may include unsuccessful collection steps, documented returned payments, enforcement results or clear statements about an inability to meet liabilities. Their legal weight depends on the overall picture.
Distinguish a temporary payment delay, a claim dispute and inability to pay. A debtor may dispute one invoice because of alleged defects while paying other due liabilities. Conversely, one payment after filing does not automatically resolve a broader payment crisis.
