We had a guy come in who was being foreclosed on. For a house in California. That he didn't own, didn't live in, in fact - he'd never been to California. The guy just had the same name as the California homeowner, and the bank was like 'Alright, that matches up! Serve him the papers, Johnny!'
You'd think this could be cleared up by a friendly phone call, but the bank totally DNGAF. They wanted this guy to show up at the hearing IN CALIFORNIA and prove he wasn't the guy. No idea how it ended up (The guy just came in for a consultation, don't think he retained as that wasn't really our field) but we've had other clients in the same situation with foreclosure judgments for property they didn't own, that was owned by some person in the same area with a similar name. Not too many, but the banks seriously did not do any detailed research for a time when everything was foreclosing. It was a huge mess.
Like, people owning two properties, one in FC and the other current - the bank would lock them out of the current home. The bank would FC on the house but forget to notify the HOA, and two years down the road the former homeowner gets sued for non-payment of HOA fees...that the bank was responsible for when they took over ownership. Banks confirming they got the suggestion of bankruptcy (which will stop a foreclosure) and then just having the foreclosure sale anyway. I am so glad I'm not dealing with that anymore.
