Regarding Personnel Loan

Dear sir,
I joined a private company in feb 2015 and have previous experience of 9 years,after one moth of joining the company changed its name.and my salary slip contains new name but old name in appointment letter.meanwhile I was in need of a personnel loan so I applied in a bank, The bank officials told me that my company name is differs in there database and on my documents ,they have old name in it,so they suggested to ask my HR to change new name of company in Bank.so my concern is can I may ask to my HR to send a letter to concern bank to change its name?please suggest.

Change of name procedure involves getting permission from Registrar of Companies.
Once that procedure is over and approved,then the company will obviously have to inform bank in writing along with approval letter for making change in bank a/c also.
Just talk to your HR and find out whether they have initiated procedure for change of name in bank a/cs also.

Take a clarificatory letter from HR under company seal about change of name.
Your appointment letter and present name of company differs.
This can easily be resolved.
