  **II.23. Recovery**
  
  **II.23.1**If an amount is to be recovered under the terms of the FWC, the contractor must 
  
  repay the contracting authority the amount in question. 
  
  **II.23.2. Recovery procedure**
  
  Before recovery, the contracting authority must*formally notify*the contractor of its 
  intention to recover the amount it claims, specifying the amount due and the reasons for 
  recovery and inviting the contractor to make any observations within 30 days of receipt. 
  
  If no observations have been submitted or if, despite the observations submitted, the 
  contracting authority decides to pursue the recovery procedure, it must confirm recovery 
  by*formally notifying*a debit note to the contractor, specifying the date of payment. The 
  contractor must pay in accordance with the provisions specified in the debit note. 
  
  If the contractor does not pay by the due date, the contracting authority may, after 
  informing the contractor in writing, recover the amounts due: 
  
  (a) by offsetting them against any amounts owed to the contractor by the contracting 
  
  authority; 
  
  (b) by calling in a financial guarantee if the contractor has submitted one to the 
  
  contracting authority; 
  (c) by taking legal action.
