Removal of Hyphothecation from RC Book

I live in Chennai, India. After paying all the dues to my car loan I wanted
to remove the hyphothecation from the RC book during last month.

In this regard I approached a driving institute and got the relevant info
on the same.

Wrote a detailed letter to the RTO for removal of hyphothecation from the
RC book. Along with it I attached the following

1) Rs.100/- paid and receipt.
2) Original RC book
3) Copy of the insurance
4) Form 35 from the bank/financier
5) NOC letter from bank/financier
6) Pollution certificate (from petrol bunk)

and went to the KK nagar RTO office during a week day after 10am and submitted
the papers. After 3 days visited the office around 4pm and collected my RC book
with hyphothecation removed.
