OMG!! I gotta tell my BIL and sister that. They think that the four of us should buy property in Puerta Vallarta or Ixtapa. That situation you just described is really terrible. I thought Vincente Fox was supposed to be more of a modernist. Looks like Mexican is mexican is mexican huh? They make the rules to fit the situation and you don't want to end up in one of their jails.
If you managed to navigate through the 4 parts to the article, it is the best explanation of the situation I have yet seen. My Bro-in-law lost about a quarter million for his house and lots, he paid it out-of-pocket.
I am told the reforms since do more to preclude such from ever happening again. At the very lest, much of the PRI corruption (which is where the article places blame) has been cleared up since Mexico wants US money. however, I don't know and can't vouch for individual circumstances.
I suppose you would need an honest Mexican lawyer. Something where the banks can't simply cancel the "fideicomisos" would be nice.
