Car sold but not transferred by the buyer in his name-remedy

There’s more to buying or selling used vehicles than shaking hands and accepting (or writing) checks. There’s a protocol to follow, requiring you submit specific forms to the Department of Motor Vehicles (DMV). These forms are then processed and filed to legally complete the title transfer.

1)I think the transfer forms have a validity of 30 days from the date of signature.

2) If that is already over one can/ should  complain to the Police Stations of both the buyer and the  sellor ( I did ) setting out the facts and keep a record of the same as well as followup.. In my case, the SI called the buyer to my residence and the Scooter was left back in my possession till registration was transferred by the buyer.

Thanks  Hardeep ji

Can u tell me which law governs this validity thing? Is it tthe Motor Vehicles Act?
