Rule 13(1) of Indian Arms Rules, 1962 is as follows:
13. Of retainers.—(1) When the owner of any arms or ammunition licensed in Form III
applies for permitting his agent, relative or employee to possess or carry any of the arms
or ammunition covered by the licence for sport, protection or display, on his behalf,
whether in attendance on him or not, and in circumstances different from those
mentioned in the proviso to Section 3, such agent, relative or employee may, if the
licensing authority considers it fit, be shown as a retainer by entering his name and other
particulars in Column 6 of the owner's licence in Form III.
Its not possible for me to add a retainer in my license now
