Registration of charges for debentures requires submission of particulars under Companies Rules Form No.10 1956. Form No. 10 prescribes the particulars required for the registration of charges for debentures under the Companies (Central Government's) General Rules and Forms, 1956, consolidating and substituting the earlier Form Nos. 10, 57 and 58; it operates as the formal instrument for recording and notifying charges created in respect of debentures for statutory registration.
