This thread is created to discuss all issues related to RTO, likes transfer of vihicle,NOC, registration etc. Many rules are state specific. Only when one experience the situation one come to know that "this is the way the things gas to be done at this place". For example when I took the NOC from chennai the rule that I came to know from Chennai was that within 6 months One has to register it in other state. But in Goa the rule is that within one month it has to be reported to the concerned RTO. I need to know the procedure for cancelling the NOC at chennai. What I know is that one has to go there and give a letter that taken from the RTO to where the NOC is issued, saying that the vehicle is not registered in that RTO. So the former RTO will cancel the NOC. A certificate from Crimes division stating that the vehicle is not involved in the accident may also required(Not sure). Is there anything extra that is required for NOC cancellation. Do I have to take the car to previous RTO for NOC cancellation? If any one can provide information/contact about any agents who can do the work it will be really helpful. My car is reg in Chennai central Aynavaram. Thanks.
