Mexico family trip pack: three documents, one set of answers

A grandparent is driving your child and the family truck to Mexico and neither parent is going. You would normally need three separate documents, each asking for the same names and dates again. This pack asks once and gives you three PDFs, in English and Spanish side by side: the child travel authorization, the medical authorization and the vehicle owner’s permission. It costs $29, against $35 for the three bought one by one.

Who this pack is for, and what each document does

It is for a trip where a child travels from the United States to Mexico with an adult who is not a parent, in a vehicle that belongs to someone else, usually a parent who stays home. If a parent travels with the child, you probably need less than this, and if the vehicle is yours and you drive it, you do not need the permission letter.

The travel authorization is the one with the strongest backing. CBP strongly recommends that a child traveling with an adult who is not a parent carry a letter authorizing the trip, naming the custody adults and giving their contact details, and highly advises notarizing it. [1] Mexico’s own migration rules about children concern those who leave Mexico, so for a foreign child entering we found no federal letter requirement. [2]

The medical authorization covers the gap between emergencies and everything else. In an emergency the General Health Law lets the accompanying relative authorize treatment and, if that is not possible, has the provider act at once to preserve life and health. [3] A fever or a sprained ankle is not an emergency, and this document lets the parents name who may consent to routine care, with the child’s allergies, medications and insurance on the same page.

The vehicle letter is the one to read carefully. Mexico’s customs agency lists the documents an importer must show for the temporary import permit, and an owner’s permission letter is not among them; insurers say drivers of a car that is not in their name could be asked for one. [4] [5] It records the owner’s consent, the driver and the vehicle identifiers, and it is not a replacement for the title, the permit or Mexican auto insurance. The Customs Law also limits who may drive a vehicle imported by a Mexican resident abroad, so check the driver’s citizenship first. [6]

If a lienholder or lessor is involved, it has to issue its own authorization, and we do not provide that letter. An airline, a border officer or an insurer decides what it accepts, and the pack promises nothing about that.

What you get

How it works

  1. Answer the questions below once. Add the second parent if both have parental authority and the second owner if two people are on the title.
  2. Look through the free, watermarked preview of all three documents. Nothing is stored to make it.
  3. Pay once ($29, no subscription) and download the three PDFs.
  4. Print them. The parents sign the first two, and the owners sign the vehicle letter, each in front of a notary public with photo ID.
  5. Give the originals to the traveling adult with the child’s passport, the vehicle title or registration, the temporary import permit and Mexican auto insurance, and keep copies. Mexico’s customs agency says the permit can be requested online 10 to 60 days before the trip. [4]

Is there a free official form?

No authority publishes a model for any of the three. CBP lists what a travel letter should contain, and the insurers’ guides list what a vehicle permission letter usually includes; this pack prints those items. [1] [5]

The temporary import permit itself comes from Banjercito and is requested separately. [4]

Medical authorization

What care the traveling adult may consent to. Insurance and doctor are optional: fill in each pair or leave it empty.

Vehicle owner (as on the title or registration)
Owner 1
Vehicle and driver

The traveling adult is the driver. Mexican law treats Mexican citizens driving a foreign-plated vehicle differently: read the notes on this page.

Letters I, O and Q are never used in a VIN.

If the vehicle has a loan or lease, its lienholder or lessor must give you its own letter. We do not provide that letter.

Frequently asked questions

Do I get three separate PDFs?

Yes. Each document has its own PDF, signature blocks and notary area, so you can sign them separately and hand each to whoever asks for it.

Is the pack cheaper than buying the three?

Yes: $29 for the pack against $35 for the same three bought separately ($14, $12 and $9). The documents are the same.

Does the traveling adult have to be the driver?

In this pack, yes: the adult who travels with the child is named as the driver of the vehicle. If someone else drives, buy the documents separately.

Can a Mexican citizen drive the vehicle with the owner’s letter?

The letter does not decide that. The Customs Law limits who may drive a vehicle imported by a Mexican resident abroad, and others only with the importer on board. [6] Check before you lend the vehicle.

Will Mexico require these documents?

We cannot say that it will. CBP recommends the travel letter, the General Health Law covers emergencies without one, and the customs agency’s list for the vehicle permit does not name a permission letter. [1] [3] [4]

Is this legal advice?

No. We are not a law firm and the documents come from fixed, versioned templates. For a custody dispute, a court order or a customs question about a specific vehicle, talk to a licensed professional.

What happens to the information I enter?

The preview stores nothing. After purchase your answers are encrypted and deleted with the PDFs 30 days after delivery.
