Non-migration certificate is used in case you want to get NOC cancellation done. If you have moved to another state with/without your vehicle and got you NOC issued for the new state from your old RTO but due to any reason you are not willing to register your vehicle to the new state, you need to take a Non-migration certificate form the RTO where you were willing to register your vehicle
You need to submit the Non-migration certificate to the old RTO as a proof that you have not registered your vehicle over there and you are looking forward to cancelling the NOC issued by them.
