Documents for nationalize vehicle

What documents are needed to nationalize a vehicle?

Will a Texas Notorized Bill of Sale be accepted?  Or do I have to wait 30 days for the Texas Title to arrive
after purchase of vehicle, before attempting to Nationalize?

I plan on purchasing a used SUV, Boat, Motor, & trailer.   Any info will be appreciated.

They want a title document

and if it were purchased in canada where there is no such thing?
if they are new,there will be a bill of sale and the car and trailer will be registered and licensed in the province of purchase.is all. i don't know about the boat other than bill of sale.

For Canadians provincial insurance or registration document

as far as i know only bc,saskatchewan and manitoba have provincial insurance.
what if one were to get jalisco state plates through certain connections at the federal and state without nationalizing a vehicle which is already here? have you heard of this being done successfully?

At one time, about 8 years ago, I bought a car in TX and needed a TIP.  At that time Banjercito required title papers.  I was given an official letter, in Spanish, by the Texas DOT stating that I was the owner of the vehicle and my title was being processed.  The Banjercito officer glanced at the letter, like he has seen it before, and issued the TIP.  

That still might be available and acceptable on the Mexican side of the border for nationalization.  Check with CBP to see if they will accept a similar letter for the USA side of things.

Nationalizing wuz the Easy Part.... getting Jalisco Plates wuz The Nightmare....

Spencer & His Crew saved the day.... ( after a couple of attempts )

Thanx Again....
