Most auction houses I've worked with have a system in place to check that the horses sold through them are not stolen. The slaughterhouse my uncle worked at also had a similar system, to ensure that the horses were being brought in by the real owners.
Unfortunately, unless the horse is microchipped or the theft is reported immediately to local authorities, there isn't a real easy way to say whether a horse has been stolen or not. 'Least not one that I've heard of.

And just because some slaughter houses mistreat their animals, doesn't mean every other one does as well.
