Latin American courts are, like pretty much all institutions in the region, mostly corrupt, nationalistic, petty and resentful of the United States.
They see American parents and don't want to do anything to help them because the American government has the power to help them itself if it really wanted to.
I see government agencies and courts in Mexico doing all sorts of work in my case... but they are all, literally, working very hard to avoid actually doing anything. They do more work and research to not do real work than they would need to do if they just did their job in the first place. It's retarded and would almost be funny if it didn't involve abducted children. Every single motion, procedure, request etc, that I make is met by officials who try their very best to avoid admitting it, then try their best to have it dismissed, with the flimsiest of reasons, and then do everything they can to avoid working on it (much less resolving it,) including all sorts of interesting games and tricks, for as long as possible hoping that, if they delay long enough the situation will resolve on its own... and since the "situation" is that a Mexican parent (usually a mother) gets to keep their abducted child in Mexico (or Brazil, or any other Hague country for that matter) for at least as long as they don't resolve the case, they have no motivation or desire to see the case resolved. Just the opposite, they are perfectly comfortable with maintaining the status quo since its the resolution they'd like to see anyway.. even, and especially, if the law doesn't support the child staying, and will work hard to make no decision if the only decision the law supports is the one they don't like.
These agencies/institutions see Americans and are:
1.) Not inclined to help and don't want to be seen as helping a foreigner and being a traitor.
2.) Enjoy "teaching" Americans something or other because we need some sort of lesson
3.) Feel like if they are going to do a "favor" for rich Americans they should be getting more out of it and are holding out on working on the matter until they actually do get something out of it. What might they get out of it if they drag their feet and wait for the US Government to actually get involved? Mostly money. Lots of money. The US gives trillions of dollars in Foreign Aid and assistance every year for the things "we" actually care about.
