I already said this once, but I'll try again: Courts only consider the facts introduced into evidence. If no one introduces a fact, it doesn't exist.
In this one case, maybe it wouldn't be such a bad idea for the court to go double-check the documents. Seems straightforward, right? Does that mean that all courts now must verify all documents submitted in all cases? Whoa, that's a big new mandate. Are you willing to fund it?
And what if the low-level bureaucrat doing the search misses something that costs you your house? You can't sue the government, and there are no other avenues for doing your own research because the court does it all. I thought you wanted the government to have less authority, because they can't do anything right?
Pick your argument, please. You just switched sides again.
It's always been possible for someone to go to court with fabricated documents and claim title to a house they don't own. Small-time operators still do this all the time. The disincentive is that eventually the rightful owner shows up with authentic paperwork, and the crook is prosecuted.
What's happening now is that the banks are the ones coming to court with fabricated documents. Except they get to call their junk docs "clerical errors" and nothing happens. Except that it sometimes costs the real owners thousands of dollars and months of their lives to get it fixed ... if they ever can get it fixed.
