How to Deregister Vehicle Plates in the State of Mexico

Vehicle owners in the State of Mexico (Edomex) must complete a crucial administrative step: deregistering their license plates. This process is mandatory if you sell your vehicle, change your residence, or if the car is stolen or deemed a total loss due to an accident. Failing to deregister means you legally remain responsible for the vehicle, potentially incurring significant debts and facing severe penalties if the car is involved in any illicit activity.

The requirements for deregistering plates vary depending on the specific situation. Generally, you will need official identification, your CURP (Unique Population Registry Code), and proof of ownership, such as the original invoice and a legal document proving ownership, especially if there's a change of owner. Previous license plates or a document proving their absence are also required. For representatives, a power of attorney and their own official identification are necessary.

If the vehicle was stolen, destroyed, or declared a total loss, you must present a formal police report or an investigation file initiated with the Public Ministry, or a claim report from the insurance company. The cost for deregistering plates in Edomex varies by vehicle type. As of December 31, 2026, the fees are MXN $722.00 for private service vehicles, MXN $1,012.00 for commercial cargo vehicles, and MXN $966.00 for trailers.
