Choice of authorised representative: interim resolution professional must nominate eligible insolvency professionals to represent each creditor class. Regulation 4A requires the interim resolution professional to ascertain creditor classes, nominate three insolvency professionals per class who are not relatives or related parties and who are willing and eligible to act as authorised representatives, and to obtain their consent in Form AB of Schedule I. Nominees should ordinarily have registered addresses in the State or Union Territory with the most creditors in the class, with nearby jurisdictions permitted if adequate numbers are lacking.
