Important Things to Check Before Buying a TN31 Registered Vehicle

If you are planning to purchase a second-hand car or motorcycle registered under TN31, checking its number plate alone is not sufficient. You should verify the vehicle's documents and condition before completing the transaction.

Consider these important checks:

1. Verify the Original RC

Check the Registration Certificate and match its registration number with the number displayed on the vehicle.

2. Check Vehicle Ownership

Confirm that the seller is the registered owner or is legally authorised to sell the vehicle. Follow the prescribed ownership transfer process.

3. Review Insurance Validity

Check whether the vehicle has a valid insurance policy. Compare the registration number, engine details, and other relevant information with the policy documents.

4. Check Pending Traffic Challans

Verify whether any outstanding traffic violations or challans are associated with the vehicle.

5. Inspect the Chassis and Engine Numbers

Compare the chassis and engine numbers with the details mentioned in the RC. Any mismatch should be investigated before purchasing the vehicle.

6. Check Loan or Hypothecation Status

If the vehicle was purchased through financing, verify whether the hypothecation has been properly terminated after loan repayment.

These checks can help reduce the risk of purchasing a vehicle with incomplete documentation or unresolved legal and financial obligations.
