The proprietor of a registered charge or a person applying to be so registered, who is under an obligation to make further advances on the security of that charge, may apply to the registrar for such obligation to be entered in the register for the purposes of section 49(3) of the Act.

Except as provided in paragraph (3), the application must be made in Form CH2.

Form CH2 need not be used if the application is contained in panel F18 of Form CH1 F2..., or in a charge received for registration where the form of that charge has been approved by the registrar.

The registrar must make an entry in the register in such terms as he considers appropriate to give effect to an application under this rule.
