NOC of my bike got expired. I have not reregistered it. How to get Non utilization certificate as I am going back to my home state?

As your NOC got expired, you need to get a Non utilization certificate from RTO in your migrated state. Non utilization certificate is an official statement from the RTO stating that your vehicle is not re-registered in that state. This is because, as per the RTO records of your home state, your vehicle is in migrated state.Also, you would be able to sell your vehicle or transfer your vehicle to another state, only after submitting Non-utilization certificate. Process involved in applying for Non Utilization certificate is as follows.

1. Submit a letter requesting Non-utilization certificate to RTO in the migrated state, along with the following documents.

• ID proof 

2. Pay the road tax in the migrated state

After obtaining the Non utilization certificate, proceed to the RTO where your vehicle is registered and submit the same documents as mentioned above along with Non-Utilization certificate that you got from the migrated state.
